Abstract

Abstract: The BixTiOy-TiO2 composite film electrode was prepared using solvent thermal and adhesion method with polyvinyl alcohol. The as-prepared BixTiOy-TiO2 and film electrode were characterized by XRD, UV-Vis, photoluminescence(PL), SEM, and EDS. The bacteria in simulated ballast water was removed by photoelectrocatalysis. The effects of impressed voltage, light source and number of use of electrode on the disinfection efficiency of photoelectrocatalysis were investigated. UV-Vis experiments show that absorption of BixTiOy-TiO2 composite materials in visible light region is greater than that of pure TiO2. PL experiments prove that light quantum efficiency of composite materials is higher than that of pure TiO2. The photoelectric catalysis experiments of simulated ballast water containing 106 CFU/mL bacteria show that the sterilization efficiency reaches 100% under 20 W germicidal lamp irradiation for 2 min. The impressed voltage is 9 V and the electrode contact area with solution is 140 cm2. Sterilization efficiency remains the same when the same electrode is used repeatedly 20 times.

Key words: BixTiOy-TiO2 composite film, photoelectric catalysis, simulated ballast water, sterilization
