英文摘要：

In order to obtain a catalyst with highly efficient photocatalytic degradation of sewage, mesoporous TiO2 hollow spheres were synthesized with the environmentally-friendly carbon spheres as the template which were made by hydrothermal reaction. The crystalline phase and morphology of the prepared samples were characterized by X-ray diffraction, Fourier transform infrared spectroscopy and Scanning electron microscope,etc. The results show that the samples are pure TiOz hollow spheres with the diameter of 200 nm, and that this hollow structure has high specific surface area, which consequently provides more effective reaction area. The mesoporous TiO2 hollow spheres can photodegrade the Rhodamine B （20 mg·L^-1） by 99. 597% under 35 minutes＇ UV irradiation. It is concluded that mesoporous TiO2 hollow spheres have excellent photocatalytic activity.
