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 CCl4. NaNO3 is then used to create porous structure, and a very large surface area (SSA) (1224 m2 g-1) could be obtained. The obtained materials can activate peroxymonsulfate (PMS) for degradation of various organic pollutants effectively. By NaNO3, 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. (c) 2020 Elsevier Ltd. All rights reserved.
