Organic and inorganic sensitizers convert the energy of the incident photons into chemical energy, thus oxidatively transforming aquatic contaminants upon light irradiation under ambient conditions. Among photoactive reagents capable of photoactivating dioxygen to generate reactive oxygen species and oxidizing the aquatic pollutants, TiO2 semiconductor has been broadly applied as an environmental photocatalyst. Here, we briefly describe the characteristics of TiO2, photochemical events occurring in TiO2 photocatalysis, mechanisms underlying photocatalytic redox reactions, modification strategies, and applications for water treatment and disinfection.
