Synthesis of porous nitrogen doped carbon cage from carbide for catalytic oxidation

Nitrogen doped porous carbon cage materials are successfully synthesized using a chemical vapor deposition (CVD) method. Several carbides are selected as templates and in situ removed by CCl 4 . NaNO 3 is then used to create porous structure , and a very large surface area (SSA) (1224 m 2 g -1 ) could be obtained. The obtained materials can activate peroxymonsulfate (PMS) for degradation of various organic pollutants effectively. By NaNO 3 , the nitrogen doping styles could be regulated and the percentage of graphitic N and C O group could be increased, which will alter the PMS-based oxidation from a radical pathway to a non-radical dominated process. This study provides a novel way for synthesis of carbocatalysts, which should have great potential in environmental remediation.
