The development of low-cost and highly efficient electrocatalysts for oxygen evolution reaction (OER)with good conductivity, high specific surface area and abundant oxygen vacancies is of great significancefor the future renewable energy conversion and storage system. Herein, Ag doped NiMoO4 materials onthe Ni foam (NiMoO4/Ag/NF) with rich oxygen vacancies were successfully prepared by hydrothermalstrategy and layer by layer assembly method. The Ag ions are doped in-situ to promote electron transferand compensate for the poor conductivity of metal oxides. The suitable air annealing treatment is used tocreate rich oxygen vacancies. The high specific surface area and one-dimensional characteristics of thecross mesoporous nanorod skeleton are responsible for the increased exposure of active centers andthe rapid charge transfer behavior. The NiMoO4/Ag/NF exhibits high activity for OER in alkaline solution(an overpotential of 275 mV at the current density of 20 mA cm2) and low Tafel slope (53.67 mV dec1),and a satisfying durability in 1.0 M KOH. This study provides an effective method for the preparation ofAg doped one-dimensional nanomaterials with excellent OER catalytic performance and electrochemicalstability.
