| 碳基材料具有较大的比表面积、良好的耐酸碱性、结构易于改性以及环境友好等特性，在催化活化过氧单硫酸盐（peroxymonosulfate, PMS）方面发挥了重要作用。理解碳基材料的结构和PMS活化机制对进一步设计高性能催化剂有着十分重要的指导意义。主要综述了N、B、P原子的单掺杂碳基催化剂及其研究现状，分析了不同杂原子掺杂碳基催化剂活化PMS的反应原理，详细阐释了杂原子掺杂改善反应活性的作用机制。此外，总结了不同类型杂原子掺杂CNT用于苯酚降解，并着重阐述了杂原子掺杂CNT活性改善的主要因素。最后，提出了当前杂原子掺杂碳基材料面临的一些挑战，给出了相关的解决建议并对该领域的发展进行了展望。 |
| 英文摘要: |
| Carbon-based materials play an important role on catalytic activation of peroxymonosulfate(PMS) due to their large specific surface area, good acid- and alkali-resistance, easy structural modification, and environmental friendliness. Understanding the structure of carbon-based materials and the activation mechanism of PMS is very important for the further design of high-performance catalysts. In this paper, the recent research of carbon-based catalysts including N, B and P atoms single-doped carbon materials is reviewed. The reaction principle of various heteratom-doped carbon-based catalysts to activate PMS is proposed, and the mechanism of heteratom-doped carbon-based catalysts to improve the reactivity is explained in detail. In addition, different types of heteroatom-doped CNT for phenol degradation were summarized, and the main factors for improving the activity of heteroatom-doped CNT were emphasized. Finally, some challenges faced by heteratom-doped carbon-based materials are put forward, relevant suggestions are given, and the development of this field is prospected. |
