The photocatalyst industry has broad prospects for development due to the favorable conditions upstream and downstream of the industrial chain.

Photocatalyst, also known as photocatalyst, refers to the general name of semiconductor materials with photocatalytic function. Photocatalyst materials that have been developed include SiO2, TiO2, SrTiO3, SnO2, SnO3, ZnS, Fe2O3, ZrO2, ZnO, CdS, WO3, etc. Among them, TiO2 (titanium dioxide) is the most commonly used photocatalyst material, and titanium dioxide photocatalysts prepared from this material…
