As a photocatalyst, when TiO2 is irradiated by ultraviolet light, redox reaction occurs under the excitation of ultraviolet energy, and strong oxidative hydroxyl radicals and superoxide anion radicals are formed on the surface, which can dissociate harmful substances in the air (various Organic compounds and some inorganic substances) and microorganisms are decomposed into harmless carbon dioxide and water, so as to achieve the purposes of air purification, sterilization and deodorization.
