【Abstract】 The semiconductor-TiO2 photo-catalytic process is a very efficient technique for photode grading the environmentally relevant organic pollutants and purifying water and air. The necessary char acteristics for a photocatalytically active semiconductor and some factors effecting the photocatalytic ef ficiency, such as the particulate mineral phase, the surface modification, as well as the reactor/reaction conditions have been discussed. Some of other novel application of TiO2 photocatalysis has also been briefly reviewed.更多还原
