Abstract:
Self-cleaning and anti-bacterial activities of the photocatalyst titanium dioxide make it a superior compound for use in the ceramics and glass industry. Photocatalytic products have been on the market since 2001. Photocatalysis is a photochemical process that semiconductor materials such as titanium dioxide undergo when irradiated by light of a certain wavelength. A major drawback in commercializing conventional TiO2 photocatalysts for ceramic applications is the large band gap of these materials which restricts its usefulness to outdoor environments. Titanium dioxide ...
