Abstract
Rice-like TiO2 nanocrystals with high specific surface area are synthesized by a facile and mild solvothermal route without further thermal annealing. These nanocrystals are aggregated to form a secondary mesoporous structure. The TiO2 samples possess a large surface area of 269.9m2/g, which is approximately 5 times higher than what is observed for P25. It is found that solvothermal temperature alters the crystallinity, surface area and porous structure of the sample. Photocatalytic activity of TiO2 nanocrystals for degradation of gaseous benzene is significantly higher than that of P25. The 1D structure and high porosity contribute to the superior photocatalytic activity.
