NiMo6-S-@HCS nanocomposite material and preparation method thereof, and application of NiMo6-S-@HCS nanocomposite material in electro-catalytic hydrogen production

The invention relates to a NiMo6-S-@HCS nanocomposite material and a preparation method thereof, and application of the NiMo6-S-@HCS nanocomposite material in electro-catalytic hydrogen production, in particular to a preparation method of a transition metal sulfide nanomaterial (hereinafter referred to as NiMo6-S-@HCS for short) which is used for electro-catalytic hydrogen production, grows on a hollow carbon sphere and takes heteropoly acid as a precursor, belonging to the technical field of nanomaterials. According to the NiMo6-S-@HCS nanocomposite material, the hollow carbon sphere is used as a substrate, and the nanomaterial formed by compounding of NiS and MoS2 directly grows on the carbon sphere; and the hollow carbon sphere is used as the substrate, and NiMo6 is vulcanized through a hydrothermal reaction and compounded with the hollow carbon sphere. The preparation method is simple and feasible in preparation process, low in cost and friendly to environment, can show excellent electrochemical activity
