Creation of safety and comfort in living environment by photocatalysis

Decomposition of organic compounds and hydrophilic conversion catalytically proceed on titanium dioxide (TiO ) surface under ultraviolet (UV) light. However, the applications of the photocatalytic reactions have been restricted to UV light intensity. Hence, photocatalytic materials sensitive to visible light have been developed to obtain the photocatalytic e ects, such as bactericidal, self-cleaning and air-cleanup e ects, under light condition in indoor space. We have recently designed and fabricated e cient photocatalysts sensitive to visible light, Cu(II)-grafted TiO and WO . TiO , Visible light Interfacial charge Abstract
