摘要：

TiO2 microspheres were synthesized by the sol-gel method using the ionic liquid (IL) 1-vinyl-3-propylimidazolium iodide (VPIM+I-) as a reaction medium, then calcined at 500 A degrees C. The samples were characterized by X-ray diffraction, scanning electron microscopy, and ultraviolet-visible (UV-Vis) diffuse reflectance spectroscopy. The phase of TiO2 microspheres is anatase, and VPIM+I- is able to favor the growth of anatase phase and prevents the collapse of small pores. The photocatalytic activity of TiO2-IL was tested by degradation of 2-nitrophenol under UV light illumination. The photocatalytic activity of TiO2-IL was higher than that of samples prepared in the reaction medium without VPIM+I-.
