Photocatalytic nanocoatings in coatings


Photocatalytic self-cleaning coatings are a significant market for nanoparticulate titanium dioxide (TiO2). The market in Japan alone is valued at over $1 billion per annum.  Self-cleaning coatings based on photocatalysts are currently suitable mainly for exterior use for inorganic surfaces and coatings, but photocatalytic materials operating at the wavelength of visible light are also widely
