Palladium nanoparticles stabilized on mesoporous cerium oxide nanoparticles catalyze the reduction of substituted nitroaromatics in presence of sodium borohydride as reductant. A modified two‐step methodology was developed for the synthesis of Pd/CeO 2 nanoparticles. First the support CeO 2 was synthesized by conventional precipitation method using ammonium oxalate as precipitant and Pd/CeO 2 nanoparticles were prepared by hydrothermal treatment. The nanoparticles exhibit excellent catalytic activity and chemoselectivity for the reduction of nitroaromatics towards corresponding amine derivatives at room temperature. A kinetic study suggests that the reaction follows pseudo‐first order rate equation. Thus, synthesized catalyst represents significant role for the reduction of nitroaromatic compounds to value added amino compounds.
