Description

Preparation method and application of CuS/BiOBr heterojunction photocatalyst
Technical Field
The invention belongs to the technical field of photocatalytic materials, and particularly relates to a preparation method and application of a CuS/BiOBr heterojunction photocatalyst.
Background
With the great increase of greenhouse gas emissions, an environment-friendly solution is sought to solve the problem of excessive carbon dioxide gas, which has become a world hot spot. Among them, solar-driven photocatalysis is an optimal approach for its convenience and effectiveness. Generally, an excellent photocatalytic CO 2 reduction system requires high charge separation efficiency, good visible light utilization, and strong carbon dioxide adsorption capacity. However, CO 2 is particularly stable as a nonpolar molecule with high dissociation energy and is therefore extremely difficult to activate during photocatalysis.
CuS is widely used in the field of photocatalytic reduction of CO 2 due to its excellent electrical conductivity and strong visible light absorption capability. However, some disadvantages greatly inhibit the activity of the photocatalytic reduction CO 2, namely high recombination efficiency of photo-generated carriers, low carbon dioxide adsorption and low solar energy utilization rate and high carrier recombination rate. Therefore, the synthetic heterojunction is an effective method for improving the utilization rate of CuS solar energy and reducing the recombination of electron hole pairs. The method introduces CuS/BiOBr to form a heterojunction, can improve the photo-generated electron-hole separation efficiency, thereby improving the photo-catalytic activity, and has not been reported in the related art as a photo-catalyst for reducing CO 2.
