Abstract
The development of a highly active and stable oxygen evolution reaction (OER) electrocatalyst is desirable for sustainable and efficient hydrogen production via proton exchange membrane water electrolysis (PEMWE) powered by renewable electricity yet challenging. Herein, we report a robust Pt/Ru-codoped spinel cobalt oxide (PtRu–Co3O4) electrocatalyst with an ultralow precious metal loading for acidic overall water splitting. PtRu–Co3O4 exhibits excellent catalytic activity (1.63 V at 100 mA cm–2) and outstanding stability without significant performance degradation for 100 h operation. Experimental analysis and theoretical calculations indicate that Pt doping can induce electron transfer to Ru-doped Co3O4,…
