A novel N-doped carbon (CN) was prepared by the hydrothermal method using glucosamine hydrochloride as both carbon and nitrogen precursor, followed by a postsynthesis heat treatment. Pd@CN exhibited 9 times higher activity compared to that of commercial Pd@AC on hydrogenation of benzoic acid to cyclohexanecarboxylic acid. The influence of solvent and substituent were also investigated. Besides, the hydrogenations of various benzoic acids have been carried out over Pd@CN.
