  • The requirement to catalyst in practical water treatment was focused on in this study. Stability of TiO2 film fixed on fiber glass net after long term use was investigated by using photocatalytic degradation of phenol as probe reaction. Regeneration methods of TiO2 film after deactivation in tap water was also studied. It is showed that after being used for 50 times, the phenol removal rate decreases from 100% to 83% at 120 min of photocatalytic reaction. Nevertheless, the overall stability of the TiO2 catalyst made in this work is still acceptable. It is a feasible way to regenerate the TiO2 catalyst through soaking and UV photoreaction in distilled water.
