Abstract

Photocatalytic reduction of CO₂ technology is an important solution to environment difficulties. Due to the shortcomings of photocatalyst itself, such as weak response to light, it is necessary to improve the photocatalyst to adapt to industrialization. In this paper, the photocatalyst Bi₂WO₆ /g-C₃N₄ was designed and prepared by one-step hydrothermal method, and its photocatalytic performance was tested through the photocatalytic reduction experiment of CO₂. Through the verification of various physical and chemical characterization methods, the excellent CO₂ reduction ability of Bi₂WO₆ /g-C₃N₄ composite photocatalyst was discussed. Due to the establishment of its Z-type heterostructure, this structure enhances the transmission speed of photogenerated carrier, reduces the recombination rate of electron hole pairs, improves the utilization rate of photons.
