D. Synnott, N. Nolan, D. Ryan, J. Colreavy and S.C. Pillai,     FOCAS Institute, Republic of Ireland

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 ...
