摘　　要：综述了不同纳米金属催化剂在对氯硝基苯(p-CNB)选择性加氢制备对氯苯胺中的研究进展,探究了p-CNB的加氢反应历程,重点探讨了不同金属活性组分及与载体间的相互作用对催化剂性能的影响。Ni基催化剂价格低廉,被广泛应用于工业生产,Pt基催化剂可以最大限度的减少脱氯,Au基催化剂具有较高的选择性,而载体与金属纳米粒子间的电子转移及金属纳米粒子表面缺陷位点对催化性能有至关重要的作用,最后对纳米金属催化剂的应用前景进行了展望。The process of selective hydrogenation of p-chloronitrobenzene(p-CNB)to p-chloraniline by different nanometer metal catalysts were reviewed.The hydrogenation process of p-CNB was investigated.And the influence of interaction between active metal components and support on catalytic performance was discussed.Ni-based catalysts are widely used in industrial catalysis due to their low cost.Pt-based catalysts can minimize dechlorination and catalysts of Au have the highest selectivity.The electron transfer between the support and metal particles and the defect sites on the surface of the metal nanoparticles,play crucial roles in the catalytic performance.Finally,the application prospects are proposed.
