Abstract

Crystalline structure and surface features of metal oxide catalyst have important influence on catalysis, however, no research work has focused on the relationship between the oxygen evolution reaction (OER) catalytic activity and plane effect of Co₃O₄ nanocrystals. In this work, Co₃O₄ nanorods and nanocubes with different dominant exposed nanocrystalline planes ({110} and {100}) were synthesized to investigate the plane effects of Co₃O₄ nanocrystalline on the OER activity. Results show that the surface Co^{3 +} species of the Co₃O₄ crystal should be the active sites for OER catalysis.
