Abstract
Since the early applications in 1972 of photocatalysis by titanium dioxide by Fujishima and Honda [15], a rapid progress has taken place. The technology of TiO2 photocatalyst or photocatalysis has become very attractive in the development of construction materials and construction techniques for self-cleaning, air or water purification, and antibacterial functions. No further chemicals have to be used, only sunlight and rainwater. Photocatalyst technology is being applied on ceramic, glass and cementitious surfaces, as well as in paints. Exterior as well as interior applications exploit the benefits of TiO2 photocatalysis. Application of photocatalysis to the envelopes of buildings, road facilities and tunnels reduces air pollution, and thus contributes to an enhanced control of heat island phenomena in densely populated cities or heavy traffic areas.
