Preparation method of cobalt phosphide-molybdenum disulfide nanosheet@carbon nano-tube

The invention relates to the filed of energy storage materials and discloses a preparation method of cobalt phosphide molybdenum disulfide nano-sheet @ carbon nano-tube, wherein sodium molybdate, polyether imide, thiourea and carbon nanotubes are used as raw materials and water is used as solvent to obtain binary compound molybdenum disulfide nanosheet @ carbon nano-tube through vacuum filtrationand drying of precipitates after high temperature treatment and cooling, cobalt sulfate molybdenum disulfide @ carbon nano-tube is obtained by the reaction of raw materials dissolved in ethanol and water with cobalt acetate and ammonia, and then ternary composite is obtained by grinding, calcining, washing and drying the product mixed with sodium hypophosphite. The synthesis of ternary composite with high catalytic activity by this cheap and environmentally friendly method has high efficiency and yield and produces products with large specific surface area, multi-active sites for hydrogen evolution, and higher electro
