Abstract
Abstract Developing highly efficient acidic oxygen evolution reaction (OER) electrocatalysts is crucial for proton exchange membrane water electrolyzer. RuO 2 electrocatalysts, which followed a kinetically favorable lattice oxygen mechanism, perform a preferable intrinsic activity, but poor stability for acidic OER. Recent work often sacrifices the intrinsic activity of RuO 2 to enhance stability. The balance between the activity and stability of RuO 2 ‐based catalysts is still overlooked in current research. Here, we report a controlled method to introduce metallic Ru onto RuO 2 catalysts to form the Ru 4+ ─O─Ru 0 interfacial structure for decreasing the Ru 4+ oxidation state and promoting deprotonation…
