摘要
作为经济、易得的含碳材料,生物质炭已应用于高级氧化领域。以硫酸根自由基为基础的高级氧化工艺是降解有机污染物的有效方法之一。本文综述了过硫酸盐的特点及其氧化降解有机污染物的反应原理,重点分析了生物质炭材料的非金属改性(氮掺杂、硼掺杂和硫掺杂)、金属改性、表面修饰等改性方式对其活化过硫酸盐降解有机污染物的影响,讨论了生物质炭基催化剂对典型有机污染物的降解效果与机理,并展望了生物质炭基材料在活化过硫酸盐降解有机污染物领域的技术挑战和发展前景。
As an economical and readily available carbon-containing material,carbon derived from biomass had been used in advanced oxidation fields.The advanced oxidation process based on sulfate radical was one of the effective approachs to degrade organic pollutants.In this review,the characteristics of persulfate and the reaction principle of oxidative degradation of organic pollutants were reviewed.The effects of non-metallic modification(nitrogen doping,boron doping and sulfur doping),metal modification and surface modification on the degradation of organic pollutants by persulfate activated by biochar materials were analyzed.The activation properties and mechanism of different kinds of biochar-based materials on persulfate,as well as the degradation effect and mechanism of the carbon-based materials on typical organic pollutants were discussed.Finally,the technical challenges and development prospects of carbon-based materials in the field of activated persulfate degradation of organic pollutants were proposed,in order to provide the reference for the research on persulfate degradation of organic pollutants.
