摘要
综述了近年来认同度较高的3类活化机制,即自由吸附、表面活化自由基氧化、非自由基氧化机制,分析对比了活性炭、生物炭、碳纳米管、石墨烯、纳米金刚石等碳材料的催化特性。分析了不同活化机制和表面改性方法之间的联系,讨论了元素掺杂、金属负载、高温退火、酸碱处理4种改性方式对表面形貌控制和官能团调控的实际运用,旨在强化碳材料的活化性能及催化稳定性,提高重复使用性能,提出了对碳活化过硫酸盐机制研究和材料改性发展方向的展望。
Three types of activation mechanisms with high recognition in recent years,namely free adsorption,surface activated radical oxidation and non-radical oxidation mechanisms,were reviewed,and the catalytic properties of carbon materials such as activated carbon,biochar,carbon nanotubes,graphene and nano diamond were analyzed.The relationship between different activation mechanisms and surface modification methods was analyzed.The practical application of four modification methods of element doping,metal loading,high-temperature annealing and acid-base treatment on surface morphology control and functional group regulation was discussed.The purpose is to strengthen the activation performance and catalytic stability of carbon materials and improve the reusability.The development direction of carbon activated persulfate mechanism and material modification was proposed.
