Electrocatalysts can help to obtain chemicals from renewable raw materials or to use alternative energy sources. But testing new catalysts brings challenges.

Researchers at the Ruhr-Universit├Ąt Bochum (RUB) and the University of Duisburg-Essen have developed a new method of depositing catalyst particles to tiny electrodes. It is inexpensive, simple and quick to perform. In order to characterize catalysts and test their potential for various applications, researchers have to fix the particles to electrodes so that they can then be examined, for example, with transmission electron microscopy.
The new method is described by Dr. Tsvetan Tarnev and Professor Wolfgang Schuhmann from the Center for Electrochemistry at RUB with Steffen Cychy and Professor Martin Muhler, RUB Chair of Technical Chemistry,…
