High-entropy RuO2 catalyst with dual-site oxide path for durable acidic oxygen evolution reaction

Abstract Developing durable acidic oxygen evolution reaction catalysts is critical for industrial proton exchange membrane water electrolyzers. We incorporate high-entropy atoms (Co, Ni, Cu, Mn, Sm) into RuO2 (RuO2-HEAE) via annealing, achieving remarkably high stability (>1500 h at 100 mA cm− 2)...
