Photocatalytic self-cleaning coatings are a significant market for nanoparticulate titanium dioxide (TiO2). Nano-TiO2 surfaces (coated with 10-20nm layer of TiO2) are commercially available and have been used in (mainly in the Japanese and European markets) in water and air purification, self-cleaning glass, concrete products and a variety of coatings applications.
These coatings greatly benefit building maintenance, especially for skyscrapers, as they reduce the need for costly surface cleaning. Various types of surfaces with TiO2 can be covered to make them self-cleaning under sunlight as well as room light. Thus, surfaces based on paints, ceramics, glass, cementitious materials containing active photocatalytic titania nanoparticles have widespread applications to create environmentally clean areas within their proximity.
Self-cleaning photocatalytic coatings utilizing UV light are currently suitable mainly for exterior use for inorganic surfaces and coatings. Photocatalytic materials operating at the wavelength of visible light are also widely studied. Industries impacted by self-cleaning photocatalytic coatings include:
Self-cleaning architectural glass
Self-cleaning automotive glass
Roof coatings to to reduce pollution through the degradation of sulfur and nitrogen oxides)
Road and tunnel coatings.
Medical (self-disinfecting coatings)
Coatings for the elimination of VOCs and odors in public spaces.
Air purification (indoor)
Self-cleaning solar cell coatings.
Applications make use of the self-cleaning, anti-fogging, anti-microbial or water cleaving properties. In indoor environments, most surfaces, e.g.. ceramic tiles, windows glass or paper, are gradually covered with organic matter such as oils, dirt, and smoke residue and become fouled.
