Study on Photocatalytic Performance of F-Doped Nanometer TiO2
F-doped TiO2 by hydrothermal synthesis method is prepared in this paper. By basis of sunlight and porous nickels as the carriers, the samples were characterized by Transmission electron microscopy (TEM), scanning electron microscopy (SEM), infra-red (FT-IR) and diffuse reflectance spectroscopy (UV-vis). The photocatalytic performances of the samples were estimated by degrading Rhodamine B. which indicates that the reaction of photocatalytic degradation of Rhodamine B follows the zero order kinetic law. The photocatalytic performances are increased by F-doped. And F optimum doping dosage is 2.0%. After calcination at 500°C, the photocatalytic performance of the sample has not been obvious improved.
