Porous carbon supported nano metal catalysts play an extremely important role in the industrial catalysis field. In recent years, with the development of the nitrogen doped porous carbon materials, the high catalytic activity and long term stability of the nitrogen doped porous carbon supported metal catalysts attract special attention. However, the design of high catalytic activity and high selectivity nitrogen doped porous carbon supported nano metal catalysts and understanding the intrinsic catalytic mechanism is still a big challenge. In this project, in search for a suitable catalyst for the chemoselective hydrogenation of aromatic compounds for example benzoic acid and derivatives, new nitrogen doped hierarchically porous carbon will be designed and synthesized at first, these functional carbon materials were then be used as supports for the deposition of nanometals and the as made catalysts will be used as heterogeneous hydrogenation catalysts for the chemoselective hydrogenation of aromatic compounds. The research will focus on the interaction between the nitrogen doped carbon supports and the nano metal and the improvement of the mass transport induced by the hierarchical pores. The intrinsic relationship between the carbon structure and the catalytic activity will be finally given after evaluating by both experiments and theoretical calculations. The realization of this project would provide important guidance for the new catalysts design and synthesis.
