Titanium tetrabutoxide is used as raw material. Sol - gel process and technique freeze - drying are applied to prepare nanocrystalline In2O3 - TiO2 with well-proportioned size. XRD, LDPSA, SEM, UV are used to characterize the powder samples, and the connection between physical characters of the complex semiconductor with different concentration of indium and its photocatalytic activity is discussed. The photocatalytic activity isevaluated by the photocatalytic decomposition of methyl orange and butylrhodamine, which are different structure materials. It is found that the complex semiconductor can be helpful to photodegrade different structure pollutants and the photocatalytic activity of n(In)/n(TiO2) = 0.1% sample is the best, whose photocatalytic activity is improved when it is used to decrease COD of printing and dyeing wastewater.
