New multimetallic catalytic systems for the selective hydrogenation of nitric acid to hydroxylamine were developed by investigating the promoter effect of one or more additional metals from Group 8 to 11 on Pd/C (combined with GeO2). Among various multimetallic catalytic systems investigated here, Pd + Ni/C, Pd + Ni + Fe/C, and Pd + An + Fe/C (combined with GeO2) were found to be particularly effective systems, which provided much higher catalytic activity as well as higher selectivity than those of not only the non-doped Pd/C system but also the Pd + Fe/C system developed recently.
