摘　　要：采用沉淀法,在不同分散剂作用下制备了Pd/C催化剂,并对制备的催化剂进行表征分析。以邻硝基苯胺为原料,研究了Pd/C催化剂在硝基还原催化加氢反应中的性能。结果表明,在分散剂B的作用下所制得的5%Pd/C-B催化剂分散度较高,且在邻硝基苯胺加氢还原反应中表现出优越的催化性能。Precipitation method was used to prepare Pd/C catalyst using different dispersants,and the prepared catalyst was characterized and analyzed.Using o-nitroaniline as raw material,the performance of Pd/C catalyst in the hydrogenation reaction of nitro reduction was studied.The results show that the 5%Pd/C-B catalyst obtained under the action of dispersant B has a high degree of dispersion and shows excellent catalytic performance in the hydroreduction of o-nitroaniline.
