    Abstract: PROBLEM TO BE SOLVED: To ensure high selectively by doping iridium with at least one kind of element selected from among Mn, Co, Fe, Ni, Cu and Ru. SOLUTION: This catalyst contains iridium by 0.3-12wt.%, especially O. 5-7wt.% of the amt. of the carrier material and at least one kind of metal selected from among Mn, Fe, Co, Ni, Cu and Ru by 1-100wt.%, especially 5-50wt.% of the amt. of the iridium. It is produced by suspending a carrier in water, adding a soln. of salts of the required metals and reducing the salts with a water-soluble reducing agent at 0-100 deg.C. When this catalyst is used, a substd. arom. nitro compd. can be converted into the corresponding arom. amine by hydrogenation with high selectivity without producing a dehalogenated product and other undesirable by-product.
