Abstract
Anatase mesostructured TiO 2 nanocrystalline was prepared in a mixture of 1-butyl-3-methyl-imidazolium tetrafluoroborate (BMIM +BF 4 −) ionic liquid and water by a low temperature hydrothermal method. The obtained materials were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and N 2 adsorption–desorption. The existence of BMIM +BF 4 − enhanced the polycondensation and crystallization rate, which encouraged the formation of anatase crystal. The TiO 2 particles were thermally very stable and thus resistant to anatase-rutile phase transformation during calcination at high temperatures. The anatase TiO 2 showed high photocatalytic activity in the degradation of p-chlorophenol than that of the commercially available TiO 2, Degussa P25. After 2 h reaction under the UV-irradiation of 250 W, the removing rate of p-chlorophenol was up to 96.3%.
