Crystal Facet Regulation and Ru Incorporation of Co₃O₄ for Acidic Oxygen Evolution Reaction Electrocatalysis.

ABSTRACT: Acidic oxygen evolution reaction (OER) has long been the bottleneck of proton exchange membrane water electrolysis. Ru- and Ir-based oxides are currently state-of-the-art electrocatalysts for acidic OER, but their high cost limits their widespread application. Co₃O₄ is a promising alternative, yet the performance requires further improvement. Crystal facet engineering can effectively regulate the kinetics of surface electrochemistry and thus enhance the OER performance. However, the facet-dependent OER activity and corrosion behavior of Co₃O₄ have not been thoroughly studied. In this study, we systematically investigated the OER performance and crystal facet dependency of Co₃O₄. The results demonstrate that Co₃O
