Abstract

The photocatalytic activity of TiO₂-Cu²� thin film has been studied over Naphthol Blue Black (NBB) in aqueous solution. The thin film has been prepared by sol-gel dip-coating method and the photocatalytic degradation of NBB was carried out in a 400-mL cylindrical photoreactor. The results showed that the photoactivity of TiO₂thin film was enhanced by doping TiO₂-Cu²� ion into the film (as TiO₂₋Cu²� thin film) and also the addition of H₂O₂ into the system. On the other hand, it also found that higher thickness of the thin film has contributed to the higher degree of NBB degradation. The best experimental condition was comprised of 10-layer TiO₂-Cu²� thin film and 1 X 10-4 mol/L H₂O₂ with the existence UV radiation where 24% of the NBB in the aqueous solution was successfully degraded.
