摘　　要：基于过氧单硫酸盐(PMS)的高级氧化工艺(AOPs)在高效去除难降解有机污染物的领域中具有广阔的应用前景。生物炭是可再生或废弃生物质碳化的固体产物,水热碳化是生物质资源化的低耗能过程,它的主要产物是水热生物炭(HC)。由于HC具有丰富的表面官能团,同时在制备过程中其表面组成和结构较易进行优化调控,HC作为一类新兴碳基功能材料用于催化活化PMS的AOPs过程对于难降解有机污染的高效去除提供了新的途径。文中从HC的生物质来源、合成方法及其活化PMS的机制、影响因素和应用等方面,阐述了HC/PMS体系去除水环境中难降解有机污染物的研究进展,并提出了该研究领域中亟需解决的问题和HC催化活化PMS研究的未来发展方向。Advanced oxidation processes(AOPs)based on peroxymonosulfate(PMS)has a broad application prospect in the field of efficient removal of persistent organic pollutants(POPs).Biochar is the solid product of carbonization from renewable or waste biomass.Hydrothermal carbonization process has the advantage of low energy consumption,and its main product is hydrothermal biochar(HC).Because HC has abundant surface functional groups,and its surface composition and structure are easy to be optimized and regulated in the preparation process,HC has been considered as one kind of emerging carbon-based functional materials.HC materials can provide a new way for the efficient removal of POPs by catalyzing the AOPs of activated PMS.In this paper,the research progress of HC/PMS system for POPs removal in water environment is summarized and reviewed.From the aspects of HC biomass sources,synthesis methods,the mechanism,influencing factors and applications of PMS catalytic activation,the urgent problems to be solved in this research field are deeply discussed.The future development and research suggestions of HC in catalysis field are put forward.
