摘要：

Influence on TiO2 Sol irradiated with UV was studied by UV-Vis absorption spectra, dynamic laser light scattering(DLS) and TEM. The results show that absorbance of TiO2 sol decreased in the visible region and increased in the near ultraviolet region, and the bandgap of TiO2 sol increased during the process of UV irradiation. Comparison of TiO2 sol without UV irradiation, average size of TiO2 sol particles irradiated with UV decreased and its size distribution was more homogenous, and its crystallite was improved and anatase TiO2 was formed at room temperature.
