Abstract
Abstract Understanding the structure and dynamic process of interfacial water molecules at the catalyst‐electrolyte interface on acidic oxygen evolution reaction (OER) kinetics is highly desirable for the development of proton exchange membrane water electrolyzers. Herein, we construct a series of p ‐block metal elements (Ga, In, Sn) doped RuO 2 catalysts with manipulated electronic structure and Ru−O covalency to investigate the effect of electrochemical interfacial engineering on the improvement of acidic OER activity. Associated with operando attenuated total reflectance surface‐enhanced infrared absorption spectroscopy measurements and theoretical analysis, we uncover the free‐H 2 O enriched local…
