文摘

A series of polyethersulfone-TiO₂ (PES/TiO₂) film photocatalysts were prepared by a phase inversion technique and subsequently used in the photodegradation of methyl orange dye (MO). The photoactivity of the films increased with increasing TiO₂ content up to 13 wt% (PT-13). The photodegradation of MO followed pseudo first-order kinetics and complete removal of MO was almost achieved in acidic conditions. The PT-13 film was found to retain its high degradation efficiency even after 5 cycles indicating the stability of the film photocatalyst.
