| Résumé : |
The environmental problem is a major concern these days. There are many conventional ways to eliminate from them like adsorption and incineration, but these methods just transfer the pollutant from one phase to another, hence permanent disposal is still a problem. A new developing technology, based principally on semiconductor material irradiated by light of suitable energy are used. Among them TiO2 Photocatalysis process have received large attention these days, which is much cheaper, the reaction is quite fast and no side reactions are produced. TiO2 is either suspended or supported on inert surface, but recently Kon Corporation has developed TiO2 solution which can be coated like film. TiO2 photocatalysis is nowadays usedfor various activities like Anti-fogging effect, Water treatment, Self-cleaning effect, Air-cleaning effect and Anti-bacterial effect. The commercial success of TiO2 photocatalysis has made the paint industries to upgrade itself from a polluter industry to a pollution preventing industry. |
