Abstract: Energy and environment, as two hot issues in the world today, have attracted people’s attention.To solve these two problems, photocatalytic technology has been favored by researchers.Among them, bismuth oxyhalide (BiOX, X=Cl, Br, I) stands out in the field of photocatalysis because of its special layered structure, suitable band gap width, and excellent photoelectric properties. Based on the structure and properties of bismuth oxyhalide, research on its modification is introduced. By means of morphology control, semiconductor compounding, ion doping and surface modification, the active site exposure, transmission and separation efficiency of photo-generated carriers and light absorption performance of bismuth oxyhalide and its composites are improved. At the same time, the applications of modified bismuth oxyhalide in the fields of energy and environment are listed, and the limitations of different modification methods are discussed, in order to provide a reference for the application of bismuth oxyhalide.
