摘要：
Nanostructure rutile TiO2 was prepared in a carboxyl-containing ionic liquid, 1-methylimidazolium-3-acetate chlorine ([AcMIm]Cl), by using TiOCl2 Solution as a precursor at low temperature. The obtained nanostructure TiO2 was analyzed with fourier transform infrared (FIFIR), X-ray powder diffraction (XRD) and transmission electron microscopy (TEM). The as-prepared TiO2 present only rutile crystal phase and a novel flower-like morphology. The as-prepared rutile TiO2 shows better photocatalytic performance in the degradation of methyl orange. The template-directing performance of ionic liquid is due to the bidentate chelating complexation between the carboxylic functional group of ionic liquid and titania. (C) 2008 Elsevier B.V.
