Abstract
A simple and efficient method to prepare large and uniform palladium particles supported on oxygen-poor activated carbon is reported in this paper. Heat-treatment of Pd/C under H2 atmosphere removes the most oxygen-containing groups from the activated carbon, and results in large and uniform Pd particles with their average size about 17 nm. This catalyst was used for the solvent-free selective hydrogenation of o-chloronitrobenzene to o-chloroaniline (o-CAN). The large palladium particles improve the selectivity of o-CAN up to 99.8 %, and the oxygen-poor activated carbon exhibits a lipophilicity to decrease the resistance to the mass transfer of reactants. This catalyst shows great potential industrial application for the green and efficient synthesis of o-CAN.
