摘      要：In order to solve the crisis of energy depletion and protect the beautiful natural environment,the development of efficient,cost-effective and stable hydrogen evolution reaction(HER)electrocatalyst has attracted great attention,but it is still an urgent challenge to fabricate an abundant and low cost *** this article,a novel HER catalyst with heterogeneous structure interfaces was in situ synthesized by multi-step electrodeposition method,and the mechanism of the enhancement of its electrocatalytic activity was elucidated by the combination of density functional theory(DFT)calculation and *** initial overpotential is only 83 mV and the Tafel slope is only 58.5 mV/dec,which is better than most of other reported CoP-based *** the meantime,DFT calculations show that the incorporation of MoO_(3)and rGO leads to electron redistribution among different components,which ensures efficient adsorption and activation of H_(2)O molecules and hydrogen ***,this work will contribute to the understanding of the mechanisms associated with heterojunctions and provide guidance for the rational design of a hybrid catalyst.
