Pure TiO2, Ce-doped and Ce/Si-codoped TiO2 nanoparticles with different Ce contents were synthesized by using a sol-gel-hydrothermal method. The as-synthesized samples were annealed at 400 °C. Their crystallization was investigated by Raman spectroscope. The result showed that Ce-doping and Ce-Si codoping decreased the crystallization. The interfacial and fractal properties were investigated by synchrotron radiation small angle X-ray scattering (SAXS). The results indicated that Ce-doping induced the Porod negative deviation, and the fractal properties showed TiO2 nanoparticles codoped by Ce-Si were rougher than these of the pure TiO2 and Ce-doped TiO2. This rough surface of the nanoparticles was helpful to improve the photocatalytic activity.
