Among the many photocatalysts in use today, TiO2 is the most suitable for industrial use as it offers the most efficient photoactivity.
Two types of photochemical reaction occur on the surface of TiO2 when irradiated properly. One is the photo-induced redox reaction of adsorbed substances, and the other is the photo-induced hydrophilic conversion of the TiO2 itself. The combination of these two functions, which was first documented in the 1970s in Japanese laboratories, has opened up many new applications for TiO2, especially in building materials.
TiO2 photocatalysts impart unique cleaning properties. They are most often added to building and construction materials, like concrete and paints, to clean the surrounding air and to prevent the surfaces from soiling. Special applications on paper surfaces, plastic films and fiber products reduce odors, eliminate dirt on surfaces, and improve room air quality.
