摘　　要：通过水热法制备出MIL-101(Cr)-NH_(2),以MIL-101(Cr)-NH_(2)为载体采用浸渍还原法得到Ag/MIL-101(Cr)-NH_(2)催化剂。通过XRD、N_(2)-吸附脱附曲线和TEM手段对催化剂进行表征。研究了Ag/MIL-101(Cr)-NH_(2)催化4-硝基苯酚(4-NP)加氢生成4-氨基苯酚(4-AP)的性能。结果表明,3wt%Ag/MIL-101(Cr)-NH_(2)样品的催化加氢性能高于其它样品,仅用4 min可将4-NP催化加氢全部转化为4-AP。因此Ag/MIL-101(Cr)-NH_(2)催化剂具有较好的催化4-NP加氢性能。Ag/MIL-101(Cr)-NH_(2)catalyst was prepared by immersion reduction of MIL-101(Cr)-NH_(2)synthesized by hydrothermal method.The catalysts were characterized by XRD,N_(2)adsorption-desorption isotherms and TEM.The catalytic performance of Ag/MIL-101(Cr)-NH_(2)for hydrogenation of 4-Nitrophenol(4-NP)to 4-aminophenol(4-AP)was investigated.The results showed that the catalytic hydrogenation performance of 3wt%Ag/MIL-101(Cr)-NH_(2)was higher than that of other samples,and the 4-NP could be fully converted to 4-AP by catalytic hydrogenation in only 4 min.Therefore,Ag/MIL-101(Cr)-NH_(2)catalyst has exhihited good catalytic performance for hydrogenation of 4-NP.
