摘　　要：利用简单浸渍法制备出一系列Pd/MIL-101催化剂,并通过粉末XRD等表征催化剂。在40℃、0.1 MPa H2、无碱的条件下,利用Pd/MIL-101多相催化苯乙酮加氢生成α-苯乙醇,研究发现,负载量为2.04wt%的Pd/MIL-101催化剂在相同的反应条件下,可以在更短的时间内将苯乙酮完全转化,且选择性在96%,进一步通过时间和转化率曲线也能证明,在各个时间段,2.04wt%的催化剂催化苯乙酮加氢反应的速率是最快的,也就是催化活性最高。Pd NPs embedded on MIL-101 obtained by the incipient wetness method. Pd / MIL-101 catalysts were characterized by Power-XRD to investigate the crystal structure. Pd / MIL-101 were tested as heterogeneous catalysts for reduction of acetophenone to α-phenethyl alcohol under a mild conditons. A study of the influence of Pd loading on the catalytic activity has established that Pd / MIL-101 of different Pd loading exhibits different behavior in terms of conversion and selectivity for the reaction. The catalyst of Pd loading was 2. 04wt% exhibited the highest activity. The difference of such catalysts were studied by the curve of time and conversion. It showed that 2. 04wt% Pd loading catalyst has the highest catalytic performance.
