11.01 Active nanostructured electro-catalysts for engergy
The main goal of this project capitalizes upon recent discoveries and new fundamental understanding in the field of electrocatalysis to develop nanostructured materials capable to catalyze the H2 fuel generation/consumption with the efficiency never achievable before. Specifically, so-called near-surface alloy nanoparticles with concave shapes will be engineered and implemented in membrane electrode assemblies of electrolysers and fuel cells. Those devices are crucial in sustainable energy provision using renewable energy sources. This target requires efforts of scientific teams with broad interdisciplinary expertise in chemistry and physics, material science and engineering. Therefore, this project brings together two groups at TUM. The group of Prof. Bandarenka (Physics of Energy Conversion and Storage) at the Department of Physics will use its expertise in the electrocatalysis using model electrodes to fundamentally understand the reaction mechanisms from which novel catalyst concepts can be developed to optimize the catalyst performance, while the group of Prof. Gasteiger (Technical Electrochemistry) at the Department of Chemistry will engineer them to have in actual electrolysers and fuel cells.
