Astonishing effect enables better palladium catalysts
(Vienna University of Technology) The taste of the chocolate cake's icing should not depend on whether it is served on a porcelain or a silver plate. Similarly, for chemical reactions on the surface of large precious metal grains, the substrate (the so-called support) should not play a crucial role. Experimental studies performed at TU Wien led to surprising findings. Chemical processes on palladium grains, which are also used for exhaust gas catalysts, changed significantly when they were placed on specific support materials.
