Abstract: A simple two-step hydrothermal method and annealing process are used to prepare heterostructured Co3O4@CoMoO4 arrays on nickel foam.Thanks to its 3D heterostructure and synergy effect,Co3O4@CoMoO4 has a higher specific surface area and better electrocatalytic oxygen evolution performance than Co3O4/NF.The as-prepared Co3O4@CoMoO4/NF presents excellent oxygen evolution stability,achieving a low overpotential of 253 mV at 50 mA cm-2 with a Tafel slope of 64 mV dec-1 in 1 M KOH solution.Therefore it has good application prospects as catalysts for oxygen evolution reaction.
