摘要：By hetero atom doping, a nitrogen-doped porous carbon was synthesized and applied to catalytic oxidation removal of NO. The synthesis conditions and NO removal process conditions of the modified carbon material were investigated, including calcination temperatures, impregnation amount, NO inlet concentration (100-500 ppm) and catalytic reaction temperature. The results showed that the dicyandiamide impregnation solution concentration of 0.5 M, and the calcination temperature of 600 degrees C performed the best in the preparation of structurally stable nitrogen-modified carbon. Due to the formation of a large number active centers of pyridine nitrogen (N-6) groups and graphitic nitrogen (N-Q) groups, the optimal conversion rate of NO could reach 67.2%. Graphic
