Abstract

Hydrogen is a feedstock in many chemical processes and can also be used as an energy carrier to store, move, and deliver energy produced from other sources. Recently, hydrogen is of interest for storing renewable electricity and helping address the intermittent nature of electricity generation from renewable sources.1 Water electrolysis plays a pivotal role in achieving a green hydrogen economy by sourcing electricity from intermittent renewable sources. However, the efficiency of the electrolysis process is limited by the sluggish oxygen evolution reaction (OER) kinetics,2-5 whereas the kinetics of the hydrogen evolution reaction (HER) are more facile. My work focused on tailoring oxide electrodes by controlling their composition, strain and crystallographic orientation to enhance the intrinsic activity of the OER. Furthermore, the stability of these electrodes driving the OER and availability of low-cost earth-abundant materials has been focused on to eventually develop active, stable and relatively inexpensive OER electrocatalysts.
