As we all know, supported metal catalysts have attracted much attention because of their unique structure and better performance in certain catalytic reactions. Studies have shown that highly graphitized carbon promotes the reduction of nitrobenzene by enhancing electron transfer . Carbon materials have the advantages of flexibility for tailoring the pore structures and the potential for modification of the catalytic surface sites via introducing heteroatoms . Up to now, there have been several developed methods to modify the properties of carbon materials via activation with varied regents or doping with nitrogen, sulfur, phosphorus, etc . According to the report, N modification is expected to increase the activity and selectivity of the catalyst by introducing more anchor sites, adjusting the electronic structure of the central metal, and interacting with the active center of protons . The existence of N species in carbon materials changes the electronic state of carbon atoms and causes the graphite structure in carbon materials to expand and produce defect sites. These defect structures are essential for giving carbon materials superior catalytic activity and stability to selectively reduce nitrobenzene to aniline .
