Abstract: The influence of the baked temperature for TiO2 ultrafine particles on the photocatalytic oxidation reaction of SO2 was investigated. The photocatalytic activity of TiO2 baked at 320 ℃ is higher than that at other temperatures(480 ℃, 550 ℃). It may be explained by the surface state of TiO2, increasing the content of surface hydroxyl is helpful to enhance the photocatalytic activity. According to the experimental results, the first order kinetic reaction and the mechanism of the reaction were suggested, also the rate constants and half-life time were reported.
