Analysis of TiO2 photocatalysis in a pulsed discharge system for phenol degradation

Photocatalysis of supported TiO2 film photocatalyst in a pulsed discharge system for phenol degradation was studied in this paper. The obtained results revealed that the supported TiO2 film with anatase structure had preferable photocatalytic activity in the pulsed discharge system. Phenol degradation and main byproduct generation were better in the discharge/TiO2 system. The photocatalyst prepared with eight times dipping process had higher photocatalytic activity than other photocatalysts and testified a preferable photocatalyst condition in the pulsed discharge system. Furthermore, the supported TiO2 photocatalyst kept photocatalytic activity after using five times in the pulsed discharge system.
