Tóm tắt

The nanoparticles of nitrogen and carbon co-doped TiO2 were prepared by sol-gel method and then followed by hydrothennal treatment. The amount of dopants and synthesize conditions were investigated and optimized. X-ray diffraction patterns demonstrated that anatase is of a major crystalline phase in the modified TiO2 structure. SEM images indicated the fonnation of homogeneous nano particles. The intensity of light absorption in 400-600 om of the modified TiO2 was increased comparing to unmodified TiO2. suggesting a higher performance of photocatalytic activity under visible light. The photocatalytic activity of the catalyst on Rhodamine B (RhB) degradation was investigated under visible light irradiation. The degradation efficiency of N and C co-doped TiO2 on RhB was significantly enhanced as compared to bare TiO2.
