- Abstract
WO3, a visible light reaction catalyst, absorbs light at a wavelength of 470 nm and has many advantages, such as strong stability, long life, non-toxicity, low cost, and suitable band edges. In this review, the photocatalytic mechanism of WO3 in water pollution treatment is introduced, as well as a systematic summary, and some main strategies for improving the photocatalytic activity of WO3 in water pollution treatment are introduced, for example surface and morphology control, synthetic heterojunctions, and doping element. Finally, the main conclusions and prospects of WO3-based photocatalysts are pointed out. It can be expected that this review can provide guidance for designing low-cost, high-efficiency new WO3-based photocatalysts in the process of water pollution treatment and can meet the application prospects of efficient utilization of solar degradation in the field of environmental purification.
