The core idea behind Solidec is deceptively simple but technically demanding. Rather than manufacturing chemicals in enormous facilities and shipping them across continents, the company builds generators that can sit directly at the point of use, converting readily available feedstocks into the molecules a business needs, when it needs them. The technology gives businesses greater control over their chemical supply chains while reducing the storage, transportation, waste and carbon emissions that come with conventional distribution. According to the company, its initial commercial focus is hydrogen peroxide, one of the most widely used oxidizers in the world, with a platform capable of producing additional chemicals including formic acid, acetic acid and syngas.

Hydrogen peroxide is a revealing choice for a first product. The compound is indispensable to pulp and paper bleaching, textile processing, wastewater treatment, mining and semiconductor manufacturing, yet nearly all of it is produced in a centralized, energy-intensive anthraquinone process that involves hydrogenation and oxidation steps followed by extraction and concentration. The resulting solution, often shipped at relatively dilute concentrations for safety reasons, carries an enormous logistical burden: vast quantities of water are transported alongside the active chemical, and the product can decompose during storage, generating waste and hazard. An electrochemical route that synthesizes hydrogen peroxide directly from air, water and electricity at the customer’s site eliminates much of that burden, producing the chemical only in the quantities required and only at the moment it is needed.

The climate logic of distributed chemical generation extends well beyond a single compound. The global chemical industry is among the largest industrial emitters of carbon dioxide, and a substantial share of those emissions is embedded not in the reaction chemistry itself but in the movement of products: compression, refrigeration, packaging, trucking, ocean freight and the construction of depots. Decentralized generators that run on electricity, particularly when that electricity is increasingly supplied by renewable sources, can drive those embedded emissions toward zero while simultaneously insulating buyers from the price volatility and disruption risks that have repeatedly roiled chemical markets in recent years. In effect, Solidec is proposing to do for chemicals what distributed solar did for electricity generation.

The platform approach is what gives the company its ambition. Because the underlying electrochemical architecture can in principle be tuned to different target molecules, the same core technology that produces hydrogen peroxide could produce formic acid, a chemical used in leather tanning, agriculture and as a promising liquid hydrogen carrier; acetic acid, the key ingredient in vinyl acetate and countless industrial solvents; or syngas, the carbon monoxide and hydrogen mixture that serves as the feedstock for fuels, plastics and fertilizers. If the platform scales as envisioned, a single product line could address multiple multi-billion-dollar markets, each with its own concentrated production footprint and supply chain fragility.

Ryan DuChanois, founder and chief executive officer of Solidec, said the award carries significance well beyond its monetary value. Winning the Wilkes Climate Innovation Prize means a great deal to the team, he noted, adding that the company is thrilled to join the Wilkes community. He explained that the award will help Solidec deploy its chemical generation systems with its early customers, producing low-carbon chemicals on site for buyers who currently have them trucked in. That last phrase captures the company’s beachhead strategy: rather than competing for new customers in unfamiliar markets, Solidec is targeting businesses that already depend on regular deliveries of these chemicals and simply want a cleaner, more reliable way to obtain them.

The Wilkes Climate Innovation Prize, now in its latest annual cycle, was established to identify and accelerate top global ideas for combating climate change. Its designers emphasize that the prize supports solutions with genuine potential for impact but facing significant uncertainty, where traditional funding pathways or market adoption routes remain limited. Eligible solutions can be technological, policy-driven, operational, financial or hybrid in nature. Beyond the headline award itself, the Wilkes Center describes its broader mission as building an innovation ecosystem around high-potential climate solutions, connecting founders with the mentorship, networks and visibility needed to make measurable progress toward real-world deployment.

The competitive process behind this year’s award was notably rigorous. Solidec emerged from a pool of 504 total submissions, which an expert panel narrowed to nine finalists before selecting the winner. Judges evaluated candidates across five dimensions: climate-system impact and relevance; plausibility and clarity of the proposed solution; differentiation and quality of insight; clear co-benefits beyond carbon reduction; and team expertise and organizational capability. The breadth of the applicant pool is visible on an interactive world map published by the Wilkes Center, which plots the geographic origins of this year’s applications and underscores how widely distributed climate innovation has become.

Three other ventures received recognition alongside the winner. Gyre Energy, a runner-up, combines physics-based artificial intelligence, thermal energy storage and automated controls to reduce cooling costs and energy consumption for cold storage facilities, data centers and buildings, a segment of the economy whose energy demand is growing rapidly in the age of artificial intelligence. The second runner-up, WoodSyn, develops biogenic construction composites based on wood-wool cement technology, transforming restoration timber into durable building materials that store carbon over their lifetime. FABUMIN received an honorable mention as a circular food-technology company that converts legume cooking water, known as aquafaba, into a functional plant-based powder capable of replacing egg ingredients in food applications while reducing water waste, costs and environmental impact.

The formal announcement took place on Wednesday, September 23, 2026, at an in-person event in New York City timed to Climate Week, hosted at the Explorer’s Club on East 70th Street, with a simultaneous watch party at the Wilkes Center’s L. S. Skaggs Applied Science Building in Salt Lake City. Solidec co-founder and chief technology officer Yang Xia and Wilkes Center managing director Fielding Norton were available for interviews at the event. For the startup, the $250,000 prize arrives at a pivotal moment, providing non-dilutive capital to support early customer deployments and, equally important, validation from a university-based institution that has made climate innovation its central mandate. For the broader climate technology community, the award signals growing confidence that decarbonizing the invisible plumbing of the industrial economy, the chemicals that flow through factories and treatment plants every day, deserves a place at the center of the climate agenda.

The material at the heart of the study is niobium pentoxide, or Nb2O5, a semiconductor widely produced in Brazil, which holds most of the world’s niobium reserves. Niobium oxide has long attracted attention as a photocatalyst because of its unusual surface chemistry: it hosts both Brønsted and Lewis acid sites that can chemisorb CO2, forming an unstable carboxyl intermediate that light-driven electrons can then reduce into fuels and oxygenated chemicals. Under aqueous conditions, Brønsted acid sites become dominant, anchoring CO2 through its carbon atom and enabling the cascade of reduction steps that ultimately yield products such as methanol, a potential liquid fuel, and acetic acid, an industrial feedstock.

But acidity alone is not the whole story. The team began by synthesizing a highly reactive form of Nb2O5 using the oxidant peroxide method, dissolving a niobium oxalate precursor in water and hydrogen peroxide, heating the mixture to form a gel, and then drying and gently calcining the solid at just 150 degrees Celsius. This mild treatment preserves a disordered, defect-rich structure bristling with reactive peroxo groups, which give the material its characteristic yellow color and high initial activity. The researchers then dispersed the powder in phosphoric acid solutions at concentrations of 0.1, 0.5 and 1.0 mol per liter for 48 hours, washing and drying the resulting phosphatized catalysts, labeled Nb-0.1, Nb-0.5 and Nb-1.0 according to the acid concentration used.

To quantify how phosphatization changed the surfaces, the team measured the concentration of acidic sites through indirect potentiometric titration in alkaline suspensions, a technique that probes the Brønsted acidity of these amphoteric oxides in water. The response to phosphatization was strikingly non-linear. Acidity rose from moderate values at low phosphoric acid concentration to a peak of 0.99 plus or minus 0.07 millimoles per gram at the intermediate treatment, then fell back slightly at the highest concentration. This optimum, the researchers found, reflects a delicate balance: phosphate groups both introduce new Brønsted acid sites and clear away organic residues left over from synthesis, but too much phosphate begins to clog the very pores and sites the reaction depends on.

An extensive characterization campaign using X-ray diffraction, infrared and Raman spectroscopy, X-ray photoelectron spectroscopy, nuclear magnetic resonance, X-ray fluorescence, electron microscopy, atomic force microscopy with infrared detection and nitrogen physisorption painted a consistent picture of what phosphatization actually does. The treatment stripped residual carboxylate and carbonate species from the surface, evidenced by declining carbon content in elemental analysis and changes in the oxygen 1s photoelectron spectra, while covalently anchoring phosphate tetrahedra to the niobia framework through Nb–O–P linkages. X-ray photoelectron spectroscopy revealed phosphorus in mixed plus-five and plus-three oxidation states at 133.2 and 134.1 electronvolts, confirming the formation of a surface niobium phosphate layer rather than a separate bulk phase. Crucially, the amorphous, pseudohexagonal TT structure of the underlying oxide, built from distorted NbO6 octahedra rich in catalytically useful defects, remained intact throughout.

The textural transformation was equally dramatic. The untreated control material showed weak, Type III nitrogen adsorption isotherms, a low surface area of 13.47 square meters per gram, and pores blocked by organic debris. After phosphatization, the isotherms shifted to Type II behavior and the surface area soared more than sixfold, reaching a maximum of 82.15 square meters per gram for the intermediate sample, whose surface roughness also dropped from 154 to 65 nanometers as measured by atomic force microscopy. At the highest acid concentration, however, excess phosphate accumulation drove the surface area back down to 41.62 square meters per gram, underscoring that more is not always better.

When the catalysts were put to work, the differences became unmissable. In a quartz reactor filled with CO2-saturated water and illuminated by ultraviolet lamps at 254 nanometers, the phosphatized catalyst prepared with 0.5 mol per liter phosphoric acid delivered the standout performance. It produced acetic acid at 267 plus or minus 49 micromoles per gram per hour and methanol at 181 plus or minus 33 micromoles per gram per hour, with the two products together accounting for 99 percent of everything detected. Selectivity reached roughly 59 percent for acetic acid and 40 percent for methanol, while carbon monoxide, a common and less useful byproduct that made up about 20 percent of the control’s output, was suppressed to below 0.1 percent. Formic acid and carbon monoxide lingered only as traces of around 0.2 percent, suggesting they act as fleeting intermediates on the modified surface rather than endpoint products.

The mechanistic explanation, the researchers propose, lies in how phosphate-modified Brønsted acid sites handle the reaction intermediates. On the untreated oxide, carbon monoxide formed during reduction is released prematurely, cutting the reaction chain short and limiting yields. On the phosphatized surface, carbonate and bicarbonate species adsorb more effectively, and intermediates such as the carboxyl radical are retained long enough to undergo the additional reduction and even carbon–carbon coupling steps needed to form methanol and the two-carbon acetic acid. Control experiments, including photolysis without catalyst, irradiation under visible light, and nitrogen bubbling in place of CO2, confirmed that the product formation genuinely depended on the photocatalyst, the ultraviolet light, and the presence of carbon dioxide.

Perhaps most importantly, phosphatization solved a chronic durability problem. Peroxo groups inherited from the oxidant peroxide synthesis route are highly reactive but tend to deactivate within the first reaction cycle, and the untreated control lost essentially all activity by its second run, while continuing to emit carbon monoxide. The phosphatized catalysts, by contrast, remained functional across four consecutive four-hour reaction cycles, retaining roughly half of their initial activity even as their yellow peroxo coloration faded to white. Post-mortem analysis showed that the characteristic Raman band of the Nb–O–P bond at 872 wavenumbers and the corresponding infrared phosphate bands survived the reaction, along with carbonate signatures near 2400 to 2500 wavenumbers that pointed to active CO2 adsorption on the spent surface. Although wavelength-dispersive X-ray fluorescence recorded a partial drop in the phosphorus-to-niobium ratio after cycling, from 0.24 to 0.11, the residual phosphate layer continued to supply the Brønsted acidity and structural stability that kept the catalyst alive.

The authors caution that the acidity measured by titration must be interpreted alongside surface composition, textural accessibility and catalytic performance, and that direct confirmation of the proposed surface intermediates will require in situ or operando spectroscopic studies. They also note that the bandgap of the semiconductor, between 3.04 and 3.10 electronvolts, barely changed with treatment, meaning the performance gains came entirely from surface engineering rather than optical tuning. Even so, the message of the work is clear and potentially far-reaching: by pairing an abundant, locally produced oxide with a cheap acid treatment, the team has shown that surface acidity, when combined with accessible texture and phosphate stabilization, is a strategic design parameter for artificial photosynthesis. As the world searches for ways to recycle carbon dioxide into fuels rather than merely capture it, a modest dip in phosphoric acid may prove to be one of the most elegant tricks in the playbook.

Writing in Nature Nanotechnology, a research group led by Xun Hong of the University of Science and Technology of China and Yadong Li of Tsinghua University describes a catalyst in which isolated copper atoms are anchored to two-dimensional boron nanosheets. The material, designated Cu-SAs/B, features copper atoms coordinated by four boron atoms, forming what the authors call Cu–B4 sites. When used to catalyse the direct oxidation of methane with hydrogen peroxide as the oxidant, this apparently simple single-atom catalyst converted methane to acetic acid with a selectivity of 97 percent, a figure that places it among the most selective systems yet reported for this transformation. Equally striking was the activity: 221.3 millimoles of product per gram of copper per hour, achieved without any addition of carbon monoxide, which many earlier approaches to acetic acid synthesis had required as a co-reactant.

The significance of the selectivity number is difficult to overstate. In direct methane oxidation, the desired partial oxidation products are typically more reactive than methane itself, so catalysts tend to over-oxidize them to carbon dioxide or to produce a mixed soup of methanol, formaldehyde, formic acid and other species. Producing a single C2 oxygenate in near-quantitative selectivity means the catalyst is not merely activating methane but orchestrating a precise sequence of bond-breaking and bond-forming steps. The carbon–carbon coupling step in particular is the chemical bottleneck: it requires two different carbon-containing intermediates to meet on the surface in the right form, at the right time, and to join together before they are lost to side reactions.

The key discovery of the new study is how this catalyst manages that feat, and the answer challenges the conventional wisdom that single-atom catalysts and cluster catalysts represent separate, static design strategies. Using in situ X-ray absorption fine structure spectroscopy, the researchers watched the catalyst while it was actually working under methane oxidation conditions. What they saw was that the isolated copper atoms do not stay isolated. Under the reaction environment, and specifically in the presence of hydrogen peroxide, the copper atoms dynamically aggregate into Cu4 clusters, and when the reactive conditions are removed, they disperse back into single atoms. This reversible switching between two distinct nuclearity states happens repeatedly, meaning the catalyst is not a fixed structure at all but a dynamic ensemble that reshapes itself on demand.

Each of those two states turns out to carry a distinct job in the reaction mechanism. Through a combination of in situ spectroscopic techniques, including diffuse reflectance infrared Fourier transform spectroscopy, the researchers established that the CH3* intermediate, the methyl fragment that results from the initial activation of methane’s carbon–hydrogen bond, is formed on the copper single atoms, while the CHO* intermediate, the formyl species, forms on the Cu4 clusters. The carbon–carbon bond of the acetic acid product is then created by the coupling of these two complementary intermediates: a methyl unit contributed by the single-atom state and a formyl unit contributed by the cluster state. In effect, the catalyst divides the labour across its own two switchable configurations, so that a reaction requiring two incompatible surface chemistries can proceed on a single material.

This division of labour resolves a long-standing dilemma in catalyst design. Single-atom catalysts, in which every metal atom is individually anchored to a support, maximize atom efficiency and often excel at breaking strong bonds, but they lack the adjacent metal atoms needed to hold and combine larger carbon fragments. Metal clusters and nanoparticles, by contrast, provide ensembles of atoms capable of multi-site chemistry, but they waste material in their bulk and frequently promote unwanted deep oxidation. Conventional approaches force designers to choose one or the other. The switchable copper-on-boron system sidesteps the trade-off entirely, because the same pool of copper atoms reorganizes into whichever geometry each step of the reaction requires, and then restores itself to the dispersed state for the next catalytic cycle.

The choice of support was essential to making this dynamic behaviour possible. Boron nanosheets, a two-dimensional form of the light element boron first realized experimentally in 2016, provide a lattice in which copper atoms can be trapped in well-defined Cu–B4 coordination sites, yet from which they can still migrate and reassemble when the chemical environment changes. The researchers verified the atomic structure of the catalyst with aberration-corrected electron microscopy and X-ray absorption measurements, confirming the isolated dispersion of copper in the resting state, and then used operando X-ray absorption spectroscopy, including simulations of the X-ray absorption near-edge structure, to track the emergence of the Cu4 clusters during the reaction. Density functional theory calculations performed by the team supported the mechanistic picture, showing how the switching is triggered by peroxide and how the methyl and formyl intermediates form on their respective sites and couple to yield acetic acid.

The practical implications reach well beyond a single reaction. Methane is both a vast energy resource and a potent greenhouse gas, and flaring, venting and leakage of associated gas from remote oil fields waste enormous quantities of it every year. A technology that could convert stranded natural gas directly into liquid acetic acid, one of the world’s most widely produced commodity chemicals and itself a precursor to vinyl acetate monomer and acetic anhydride, would change the economics of gas utilization. Because the reported catalyst operates without carbon monoxide co-feed, it removes one of the major complications of earlier routes, and the use of hydrogen peroxide as oxidant suggests compatibility with relatively mild reaction conditions. The authors note that independent replication of the methane oxidation experiments by collaborators confirmed the catalytic results, an unusually rigorous check for a field where reproducibility has often been a source of controversy.

More broadly, the work establishes what the researchers call a proof of concept for switchable nanocatalysts as a design principle. Instead of freezing a catalyst into a single, optimized static structure, chemists may increasingly build materials whose active sites reconfigure themselves in response to the reaction environment, accessing transient geometries that cannot exist under ordinary conditions. The reversible single-atom to cluster transition observed here echoes related dynamic behaviour seen in other atomically dispersed metal systems, but the new study is among the first to show a switchable catalyst in which each configuration performs a specific mechanistic role in a multi-step industrial reaction. If the concept can be generalized to other metals, supports and transformations, the shape-shifting copper atoms on boron may mark the beginning of a new chapter in catalysis, one in which the most useful catalyst is not the most stable structure but the most adaptable one.
