Determining the activity of noble-metal-free catalyst particles
(PHYSorg.com Nanotechnology)

Chemists have developed a new method with which they can characterize individual noble-metal-free nanoparticle catalysts. The particles could be a cheap alternative to precious metal catalysts for obtaining hydrogen from water by means of electrolysis. `In order to develop effective nanoparticles, we need to understand how the structure and activity of individual particles or small particle groups are related to each other,` says Professor Wolfgang Schuhmann of the Center for Electrochemistry at Ruhr-Universität Bochum. He describes a new measurement method for this purpose together with the researchers Tsvetan Tarnev and Dr. Harshitha Barike Ayappa from Bochum and Professor Corina Andronescu from the University of Duisburg-Essen and other colleagues in the journal Angewandte Chemie of 1 October 2019.
