This invention discloses a sunflower-shaped tungsten oxide / indium zinc sulfide heterojunction. The tungsten oxide / indium zinc sulfide heterojunction consists of tungsten trioxide located within a central sphere and indium zinc sulfide distributed as nanosheets on the sphere's surface, forming a three-dimensional sunflower shape. Using glucose as a raw material, this invention first prepares uniformly sized carbon spheres via a hydrothermal method. Then, using the synthesized carbon spheres as a template and WCl6 as a precursor, hollow WO3 spheres are obtained through in-situ hydrolysis combined with high-temperature calcination. Finally, using the synthesized hollow WO3 spheres, indium chloride, indium chloride, and thioacetamide as starting materials, the three-dimensional sunflower-shaped tungsten oxide / indium zinc sulfide heterojunction is prepared using a water bath method. The WO3 / ZnIn2S4 heterojunction material of this invention has a larger specific surface area than pure WO3, which is beneficial for exposing more active sites. The three-dimensional heterojunction constructed in this invention can effectively inhibit the free diffusion of CO2 molecules, increase the local CO2 concentration on the catalyst surface, and is more conducive to the adsorption and activation of CO2 molecules.
