Abstract

Photo degradation of Naphthol Blue Black using TiO2 thin film has been studied. The thin film was prepared by dip-coating the pyrex tube into a sol-gel and subsequently be heated in furnace at 2°C/min until achieving 550°C. The results showed that the oxidative activity of the thin film can be enhanced by doping the Ag + ion and the addition of H2O2 in term of degradation of NBB. Further, higher degradation degree of NBB was observed as the thickness of the film increased. The process of degradation is conform the kinetics of pseudo first-order reaction with the rate constant, k, ranges from 0.0009 to the highest 0.0103 min-1.
