What Is Photocatalyst Example?

Various photocatalysts such as ZnO, ZnS, CdS, SrO₂, WO₃ and Fe-TiO₂ have been used for treatment of air pollutants. The most popular among them is TiO₂ due to its low cost, high stability, environmental friendliness. It is a semiconductor which is used for photo-induced redox reactions for degradation of VOCs.
