Effects of Sputtering Atmosphere Oxygen Pressure on Photocatalytic Phenomena in Anatase Films

Thin anatase films were successfully sputter-deposited on a glass substrate at temperatures as low as 200°C. Photocatalytic activities, evaluated through the decomposition of acetic acid under UV irradiation, showed a strong dependence on oxygen pressure during sputtering and were found to have a close relationship with the oxygen vacancy concentration in the films. Possible explanations for the vacancy concentration of films and their photocatalytic activity have been discussed.
