Catalytic activity of individual cobalt oxide nanoparticles determined
Precious metal-free nanoparticles could serve as powerful catalysts in the future, for example for hydrogen production. To optimize them, researchers must be able to analyze the properties of individual particles. A new method for this has been suggested by a team from the Center for Electrochemistry at Ruhr-Universität Bochum (RUB) and the Institute of Inorganic Chemistry at the University of Duisburg-Essen (UDE). The group developed a method using a robotic arm that allows them to select individual particles under an electron microscope and place them on a nanoelectrode for electrochemical analysis. The method is described in the journal Angewandte Chemie, published online in advance 19 November 2020.
