| Abstract: | Catalytic deactivation is one of the key factors to affect photocatalytic degradation directly in the practical application. In this paper, the study and progress of deactivation and regeneration of photocatalyst in environmental pollution control in recent years were briefly reviewed. Especially,the effect of water vapor on the photocatalytic oxidation in gas-phase was discussed.; |
