Abstract
Abstract Improving the alkaline hydrogen evolution reaction (HER) efficiency is essential for developing advanced anion exchange membrane water electrolyzers (AEMWEs) that operate at industrial ampere‐level currents. Herein, we employ density functional theory (DFT) calculations to identify Ni‐RuO 2 as the leading candidate among various 3d transition metal‐doped M‐RuO 2 (where metal M includes Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn). The incorporation of Ni atoms facilitates the partial reduction of RuO 2 , resulting in the formation of a Ni−Ru/RuO 2 interface having a significant built‐in electric field (BIEF) during electrochemical reactions. The resulted BIEF enhances electron transfer across the…
