摘要 以钛酸丁酯和Fe(NO3)3·9H2O为原料,采用水热法制备了Fe掺杂的纳米TiO2。利用XRD,TEM和UV-Vis对样品进行了表征,并研究了不同催化剂用量和pH值等因素对光催化降解次甲基蓝的影响。结果表明:Fe掺杂的纳米TiO2吸收带红移,吸收强度增大,在碱性条件下具有更好的光催化性能,催化剂最佳用量为1.0g/L。

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.
