The nanoparticles of TiO2 modified by iron and carbon were prepared by sol-gel followed by solvothermal method at relatively low temperature. The structure and properties of catalysts were characterized by XRD, SEM IR, BET and particle size distribution. The results showed that the synthesized particle sizes were about 33nm and anatase was a predominant phase in the structure of the synthesized Fe-C-TiO2. In addition, initial results from UV-Vis and HPLC chromatogram suggested that the mineralization of Rhodamine B (RhB) was almost completed after 3 hours of irradiation. The kinetics of RhB photodegradation was found to follow the first-order rate law and could be described in terms of a modified Langmuir-Hinshelwood model. Degradation rate was fast at RhB conce.ntration of 40 mg/L, whereas, it was significantly low at higher concentration of RhB. The validity of the model was also proved with other researchers'results.
