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.
