摘　　要：NH_(2)-MIL-125(Ti)具有较大的比表面积和孔隙率、均匀的孔道分布以及功能可调节性等优点,在光催化领域具有重要的应用前景,但同时也存在光生电子-空穴复合快和可见光利用率低等缺点。首先,介绍了钛酯的类型、反应物浓度、反应溶剂体积比和晶化时间对NH_(2)-MIL-125(Ti)晶体形貌的影响;接着,总结了提高NH_(2)-MIL-125(Ti)光催化活性的方法;然后,综述了国内外NH_(2)-MIL-125(Ti)光催化剂的应用现状;最后,提出了NH_(2)-MIL-125(Ti)光催化剂的发展方向。NH_(2)-MIL-125(Ti)shows great application prospect in the field of photocatalysis because of its large specific surface area,high porosity,uniform pore channel distribution and functional adjustability.At the same time,it also displays disadvantages of fast photo-generated electron-hole recombination,low utilization rate of visible light,and so on.In this review,the effects of titanium ester type,reactant concentration,reaction solvent volume ratio,and crystallization time on the crystal morphology of NH_(2)-MIL-125(Ti)were firstly introduced,followed by summarization on the methods for photocatalytic activity improvement of NH_(2)-MIL-125(Ti).Then,the application status focused on NH_(2)-MIL-125(Ti)photocatalysts at home and abroad were further discussed.Finally,the development directions of NH_(2)-MIL-125(Ti)photocatalysts were proposed.
