Electrocatalysis for Sustainable Energy Conversion
With global efforts for carbon neutrality, establishment of sustainable energy cycles including production of renewable electricity and energy conversion into useful chemicals gains immediate attention. In this regard, it is crucial to design novel catalysts that exhibit high performance in target electrocatalytic reactions, such as hydrogen evolution reaction (HER), oxygen reduction reaction (ORR) and CO2 reduction reaction (CO2RR).
Our research focuses on understanding fundamental mechanisms governing the catalytic interfacial reaction, activation, and degradation processes. By monitoring of physicochemical changes with in situ techniques combined with TEM, XRD and Raman spectroscopy, we directly monitor structural changes of catalysts during electrochemical reactions.
