Modified Titanium dioxide-based photocatalysts for water treatment: Mini review

Environmental Functional Materials, Год журнала: 2024, Номер 3(1), С. 1 - 12

Опубликована: Март 1, 2024

Titanium dioxide (TiO2), recognized for its affordability, low cost, high chemical stability, and eco-friendliness, has garnered extensive research attention in recent years. But because of the TiO2 band gap (>3.2eV) seriously limit use visible light, fast electron-hole composite often lead to poor photocatalytic activity quantum yield. Therefore, needs be modified. Modification can change broadband TiO2, enhance light absorption, thus affect important means efficiency. In this review, we introduce crystal form mechanism review some modification strategies including doping modification, construction heterojunctions, plane engineering defect engineering. Furthermore, application modified TiO2-based materials water treatment, removal dye contaminants, antibiotics, advanced oxidative sterilization, finally explore challenges prospects photocatalysts.
