The invention discloses a porous carbon/phosphorus doped molybdenum disulfide composite material derived from natural agar for hydrogen production by water electrolysis, wherein a catalyst has a hierarchical structure of molybdenum disulfide and porous carbon matrix composite, and the preparation has high dispersibility and controllable morphology. The invention has the advantages that the natural agar is used as the carbon source, namely, a novel utilization mode of biological raw materials is provided, and the process is simple; through heteroatom doping, molybdenum disulfide structural defects are caused, and the overall conductivity of the material is improved. The catalyst of the invention shows excellent catalytic activity of water electrolysis hydrogen evolution under acidic condition, and is expected to replace the currently used noble metal such as platinum base and the like. |
