Abstract 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.

碳化物催化氧化合成多孔氮掺杂碳笼

摘要 使用化学气相沉积(CVD)方法成功合成了氮掺杂多孔碳笼材料。选择几种碳化物作为模板并通过 CCl4 原位去除。然后使用 NaNO3 创建多孔结构,可以获得非常大的表面积 (SSA) (1224 m2 g-1)。所得材料可以活化过硫酸盐(PMS),有效降解各种有机污染物。通过 NaNO3,可以调节氮掺杂方式,增加石墨 N 和 CO 基团的百分比,这将改变基于 PMS 的氧化从自由基途径到非自由基主导的过程。该研究为合成碳催化剂提供了一种新方法,在环境修复方面具有巨大潜力。
