The invention discloses a method for preparing a porous carbon-loaded tungsten carbide composite material, which belongs to the field of material science and technology. The material is highly dispersed and uniformly loaded tungsten carbide nanoparticles on a carbon skeleton with a large network of pore structures. The specific preparation method is: using metal nitrate, tungsten source, fuel and soluble organic carbon source as raw materials, the precursor of tungsten oxide and other metal oxides uniformly embedded in the carbon matrix is obtained through the solution combustion synthesis reaction, and the synergistic coupling pore-forming effect is used. , after subsequent high-temperature carbonization and pickling to remove oxides, the specific surface area is as high as 1000m 2 / g or more porous carbon-supported tungsten carbide materials. The raw materials of the present invention are easy to obtain, the process is simple, and the requirements for equipment are low. The prepared porous carbon-supported tungsten carbide powder material has fine particles, narrow particle size distribution, good dispersibility, high specific surface area and pore volume, and uniform loading of tungsten carbide particles. It is not easy to fall off, and as a platinum-substituting catalyst, it can significantly reduce the cost of electrocatalysts, and at the same time improve its hydrogen evolution catalytic performance, and has good industrial application prospects.
