Transition Metal Oxides in Oxygen Evolution

This lecture discusses the role of transition metal oxides, particularly Fe, Co, and Ni oxides, in the oxygen evolution reaction. It covers the discovery of the promotional effect of Fe on Ni oxide, the active sites in NiFeOx, and the challenges in proving the active element. Various electrocatalysts for oxygen evolution are benchmarked, highlighting the importance of standardized evaluation methods. The lecture also explores the catalytic activity of Fe-doped Ni oxides compared to Fe-free Ni-containing oxides, shedding light on the different active sites for the oxygen evolution reaction. Additionally, it delves into the fundamental chemistry of CO2 and its reduction, as well as the catalysis for the electrochemical reduction of CO2.
