Abstract：Fe3+ doped nano-TiO2 were prepared by hydrothermal method using butyl titanate and Fe(NO3)3·9H2O as precursor.X-ray Diffraction(XRD),Transmission Electron Microscope(TEM) and UV-Vis Absorbance Spectroscopy were used to characterize the products.The photocatalytic activity of Fe3+ doped nano-TiO2 at the different amount of catalyst and pH values on the degradation of methylene blue(MB) were studied under 300W halogen tungsten light.The results show that the photocatalytic activity of Fe3+ doped nano-TiO2 is better at alkaline condition and the best amount of Fe doped nano-TiO2 is 1.0g/L.The band gap of Fe doped nano-TiO2 become narrow and the absorption red-shifted and the absorption intensities increased.At the same time,the recombination of e-/h+ was inhibited,so the photocatalytic activity of Fe doped nano-TiO2 are enhanced.
