Abstract The selective hydrogenation of nitroarenes is a key transformation for the production of aromatic amines, which are primary intermediates in the synthesis of pharmaceuticals, agrochemicals, and dyes. However, most reaction processes require toxic organic solvents and suffer from poor selectivity in the presence of other reducible groups. Herein, we report a successful example of nanoclusters of ultrafine Pd supported on N‐modified ordered mesoporous CMK‐3 carbon (Pd/N‐CMK‐3) prepared by a facile two‐step impregnation route with aqueous solutions of 1,10‐phenanthroline and H 2 PdCl 4 that hydrogenated various nitroarenes highly efficiently and selectively to the corresponding aromatic amines with hydrogen in the absence of solvent. The Pd/N‐CMK‐3 catalyst could be recovered easily for multiple recycling reactions without a loss of catalytic performance.
