摘　　要：溶剂热合成技术是一种有效合成复合材料的技术。在本研究中,通过溶剂热法制备了不同比例复合的TiO_(2)@MIL-101(Cr)复合材料。并利用这些材料进行可见光光催化燃油脱氮(吡啶)。对所得催化剂采用XRD、FT-IR、SEM、TEM、BET和DRS进行表征。通过活性实验结果可以得到,20%TiO_(2)@MIL-101(Cr)具有良好的催化活性,在可见光光照4 h后,对吡啶的脱除率高达70%。最后,通过对HPLC-MS数据分析,得到一个光催化燃油脱氮的可能机理。Solvothermal synthesis technique is an effective method to create composite materials.In this paper,a series of TiO_(2)@MIL-101(Cr)were prepared by the solvothermal method for photocatalytic denitrification of pyridine in fuel under visible light irradiation.The products were characterized by XRD,FT-IR,SEM,TEM,BET,DRS and ESR.The result shows that 20%TiO_(2)@MIL-101(Cr)has high catalytic activity,the pyridine removal efficiency reaches values as high as 70%after irradiation for 240 min.Finally,we obtained the possible mechanism of photocatalytic denitrification according to the HPLCMS spectrometry results analysis.
