Finding the right balance for catalysts in the hydrogen evolution reaction

(University of Tsukuba) A collaboration led by the University of Tsukuba optimized the balance between the catalytic activity in hydrogen generation and stability of metal nanoparticles coated with different numbers of graphene layers. The team found that coating the catalyst nanoparticles with three to five graphene layers provided samples that displayed high catalytic activity in hydrogen evolution as well as high stability in acidic solution. These findings should aid the development of economical processes for large-scale hydrogen production.
