Chemists at Ruhr-Universität Bochum have developed a new method to tightly fix catalyst powders on electrode surfaces. Currently, the high physical stress induced on catalyst films by gas evolving reactions hampers the application of powder-based catalysts. The developed technique is potentially interesting for hydrogen production by water electrolysis. A team involving Dr Corina Andronescu, Stefan Barwe and Prof Dr Wolfgang Schuhmann from the Center for Electrochemical Sciences reports on this in the international edition of Angewandte Chemie.
