Abstract: Research progress of catalysts for hydrogenation of dinitrotoluene to diaminotoluene was reviewed. Research achievements of (Pd+Pt)/C，Raney-Ni，supported Ni-based，Ni based amorphous alloy and Urushibara Ni based catalysts were introduced. By comparing the advantages and disadvantages of catalysts above-mentioned in production cost，preparation process and performance for dinitrotoluene hydrogenation，Ni amorphous alloy catalysts exhibited the advantage of low price，high hydrogenation performance，and similar catalytic activity and selectivity with (Pd+Pt)/C industrial catalyst at 1 MPa，so it was the first alternative catalyst for industrial noble metal and Raney-Ni catalyst. Urushihara nickel catalyst had the advantages of simple preparation process，low price and similar hydrogenation performance with Raney-Ni catalyst，with the potential for commercialization.

摘要： 综述了二硝基甲苯液相加氢合成甲苯二胺催化剂的研究进展，并介绍了(Pd+Pt)/C等贵金属催化剂、雷尼镍催化剂、负载型镍基催化剂、非晶态镍催化剂和漆原镍催化剂的最新研究成果。通过对比上述各催化剂在生产成本、制备工艺及催化二硝基甲苯加氢性能等方面的优缺点，发现非晶态镍催化剂不但价格低廉，而且在1 MPa低压二硝基甲苯液相加氢的反应中表现出与(Pd+Pt)/C工业催化剂相似的活性和选择性，是替代二硝基甲苯液相加氢贵金属和雷尼镍工业催化剂的首要选择；漆原镍催化剂制备工艺简单，价格低廉，且在众多的加氢反应中表现出与骨架镍催化剂相似的催化性能，也具有较大的工业化潜质。
