(Invited) Molecular Mechanisms of Oxygen Evolution and Water Splitting at Elevated Temperatures

Abstract

High-temperature electrolysis employing oxygen-ion-conducting solid electrolytes is a promising method to synthesize fuel. However, the molecular reaction mechanisms at the gas/electrode interface is not well-understood. In recent years, a variety of in-situ characterizations and density-functional theory calculations have elucidated the reaction mechanisms. In this talk, I will present a comprehensive understanding of oxygen-evolution and water-splitting reactions on perovskite and fluorite oxides at the molecular level.
