Abstract

The preparation of TiO ₂ photo-catalyst films on alumina balls via low pressure metal organic chemical vapor deposition using titanium tetraisopropoxide and their photo-catalytic activity in bromothymol blue (BTB) decomposition using a microwave/UV/TiO ₂ photo-catalyst combined process system were investigated. The results indicate that the film structure strongly depended on the reaction temperature. Among the grown TiO ₂ films, anatase and rutile showed high photo-catalytic activities, whereas amorphous TiO ₂ films showed lower activities. The BTB decomposition rate increased with the microwave intensity and ozone injection rate. A significant synergistic effect was observed when hydrogen peroxide addition was combined with other elemental techniques.
