Preparation method for NiCoP nano material

The invention discloses a preparation method for a NiCoP nano material. The preparation method comprises the following steps: dissolving a nickel salt and a cobalt salt into a beaker with deionized water in proportion, and stirring until the nickel salt and the cobalt salt are completely dissolved; then, heating and evaporating on the stirrer until the nickel salt and the cobalt salt are completely dried to obtain a product; putting the product into a muffle furnace, and roasting to obtain black powder; sufficiently mixing the black powder with a certain amount of phosphor salt, and heating in the presence of N2 in a high-temperature tubular furnace to react, thereby obtaining a NiCoP nano material crude product; respectively washing the NiCoP nano material crude product with deionized water and absolute ethyl alcohol in sequence, and putting the washed product into a vacuum drying oven, and drying, thereby obtaining the NiCoP nano material. The preparation method has the advantages of being low in energy consumption, low in cost, simple and convenient in reaction condition, high in safety coefficient, and the like.
