摘      要：Exploring and designing a high-performance non-noble metal catalyst for hydrogen evolution reaction(HER)are crucial for the large-scale application of H2 by water ***,novel catalysts with NiMo nanoparticles decorated on reduced graphene oxide(NiMo@r GO)synthesized by a two-step hydrothermal method were *** characterization results showed that the prepared NiMo@r GO-1 had an irregular lamellar structure,and the NiMo nanoparticles were uniformly dispersed on the ***@rGO-1 exhibited outstanding HER performance in an alkaline environment and required only 93 and 180 mV overpotential for HER in 1.0 M KOH solution to obtain current densities of-10 and-50 mA·cm^(-2),*** tests showed that NiMo@rGO-1 had a certain operating stability for32 *** the same condition,the performance of NiMo@rGO-1 can be comparable with that of commercial Pt/C catalysts at high current *** synergistic effect between NiMo particles and lamellate graphene can remarkably promote charge transfer in electrocatalytic *** a result,NiMo@rGO-1 presented the advantages of high intrinsic activity,large specific surface area,and small electrical *** lamellar graphene played a role in dispersion to prevent the aggregation of *** prepared NiMo@rGO-1 can be used in anion exchange membrane water electrolysis to produce *** study provides a simple preparation method for efficient and low-cost water electrolysis to produce hydrogen in the future.
