Summary: | The invention relates to a preparation method of a snowflake-shaped cuprous sulfide/molybdenum sulfide/platinum heterostructure with a near-infrared photothermal enhanced electro-catalytic hydrogen production effect, and the snowflake-shaped cuprous sulfide/molybdenum sulfide/platinum heterostructure is constructed by a two-step hydrothermal method and an electrochemical deposition method. The condition that the cuprous sulfide/molybdenum sulfide composite material with the mass of 45 milligrams is added into cuprous sulfide is a catalyst with the best performance and shows photo-thermal enhanced electro-catalytic hydrogen evolution performance under near-infrared irradiation is determined. After a small amount of platinum is electrochemically deposited, a Schottky barrier is formed between platinum nanoparticles and molybdenum sulfide nanosheets, and the photothermal effect and hydrogen evolution performance of the composite material are further enhanced. The cuprous sulfide/molybdenum sulfide/platinum as an |
