Preparation method and application of copper-loaded molybdenum sulfide Cu-MoS2 catalyst

The invention provides a preparation method and application of a copper-loaded molybdenum sulfide Cu-MoS2 catalyst, Na2MoO4. 2H2O and thiourea are added into water to be dissolved, the solution is heated to 180-200 DEG C in a high-pressure kettle with a polytetrafluoroethylene lining, the temperature is kept for 24-36 hours under self-generated pressure, the MoS2 catalyst is prepared, the obtained MoS2 catalyst is dispersed into a methanol aqueous solution, a CuCl2 aqueous solution is added, the mixture is stirred for 30-50 minutes, and the copper-loaded molybdenum sulfide Cu-MoS2 catalyst is obtained. And then the Cu-MoS2 catalyst is placed under a full-spectrum illumination lamp of 300-500 W to be illuminated for 1-3 h, and the Cu-MoS2 catalyst is prepared. The preparation method is simple, and the Cu-MoS2 catalyst with a good crystal form can be obtained; compared with a pure molybdenum sulfide catalyst, the constructed copper-loaded molybdenum sulfide catalyst has the advantages that the number of active
