【 摘 要 】

Pure TiO2 and a series of Al-Fe-Cu tri-doped TiO2 were synthesized by using in-situ hydrothermal method. The synthesized materials were characterized using X-ray diffraction (XRD), Fourier Transform Infrared (FTIR) and Scanning Electron Microscope (SEM). The photocatalytic activity of the samples was evaluated for degradation of methylene blue (5mgL-1) in aqueous solution under uv-visible light (λ = -1, 1626.911630.53 cm-1 and 503.30-530.93 cm-1, respectively. The degradation rate of Al(1mmol)-Fe-Cu tri-doped TiO2 showed the highest photocatalytic degradation with 93% compared to pure TiO2, Al(2 mmol)-Fe-Cu tri-doped TiO2 and Al(3mmol)-Fe-Cu tri-doped TiO2 were calculated as 76%, 85% and 80%, respectively. Hence, it can be seen that, the amount of Al ion-doping have influence on the photocatalytic degradation.
