Application of Carbon Catalysts in Catalytic Reactions

Due to its defect, some active sites were formed and some thermal catalytic reactions can be catalyzed by carbon materials. The surface structure and chemistry of carbon monolithic have been introduced firstly. The active surface sites are mainly the functional groups with heteroatoms, and then reactions catalyzed by carbon materials has been illustrated. Selective oxidation, advanced oxidation, reduction, activation of alkane, acid catalyzed reactions, electrically catalytic reduction and oxidation reactions can be catalyzed by carbon monolithic. The prepared methods of carbon catalysts, the reaction catalyzed by carbon, catalytic sites, catalytic results and mechanism have been briefly introduced. The pure carbon cannot be satisfied all the requirements of different catalytic reactions. They can be modified by doping, calcination and acid treatment to get different properties. It''s believed that with the further study of carbon catalysis, the application of carbon in catalysis will be more widely and can be industrialized near future.
