Hydrogenation of 4-Nitrophenolto catalyzed by Ag loading MIL-101(Cr)-NH2
Ag/MIL-101(Cr)-NH2 catalyst was prepared by immersion reduction of MIL-101(Cr)-NH2 synthesized by hydrothermal method.The catalysts were characterized by XRD,N2 adsorption-desorption isotherms and TEM.The catalytic performance of Ag/MIL-101(Cr)-NH2 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)-NH2 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)-NH2 catalyst has exhihited good catalytic performance for hydrogenation of 4-NP.
