摘要
With the purpose to investigate the effect of heating temperature on the visible-light photocatalytic activities of carbon-doped TiO2, TiO2 photocatalysts doped with different amounts of carbon were synthesized through heating the dried gel at different temperatures from 70 to 350 degrees C. XRD, XPS, UV-Vis analysis were used to characterize the photocatalysts. The photocatalysts are all of anatase phase with specific surface areas higher than 240 m(2)/g. Carbon could be doped into TiO2 after drying the gel at 70 degrees C. The concentration of doped carbon changes with the rising of calcination temperature. The photocatalyst calcination at 300 degrees C shows the highest photocatalytic activity under visible light irradiation, which is just a comprehensive result of physical properties of the photocatalysts.
