摘　　要：以羧酸盐取代羧酸对苯二甲酸为有机配体水热合成MIL-101(Cr),可以解决对苯二甲酸难溶于水而堵塞微孔道的问题。通过N_2吸附、X线衍射(XRD)、透射电子显微镜(TEM)等方法对以羧酸盐为有机配体合成的MIL-101(Cr)进行表征。结果表明:未纯化的MIL-101(Cr)微孔结构非常清晰,BET比表面积(S_(BET))达到2 600m^2/g;产品颗粒均匀,为60 nm的小粒径晶体,远小于传统水热法产品的粒径;以羧酸盐为有机配体合成的MIL-101(Cr)无需复杂的后续纯化过程,即可得到高纯度的产品,收率达70%。The hydrothermal synthesis of MIL-101（Cr） with terephthalate instead of terephthalic acid as organic ligands can solve the problem that the terephthalic acid was insoluble in water and hinder the micropore of the materials.The product synthesized with terephthalate was characterized by N 2 adsorption,X-ray diffraction （XRD） and transmission electron microscope （TEM）.Results showed that the microporous structure of MIL-101（Cr） without purification was open and BET specific surface area （ S BET ） was 2 600 m 2/g.The particle size of the product was about 60 nm,which was much smaller than the sizes of the samples synthesized by conventional hydrothermal method.MIL-101（Cr） synthesized with carboxylate as organic ligand did not require complex purification procedures to obtain the pure product.The yield of the product was about 70%.
