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1MPa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。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.
