摘要
以光催化材料为基础的高级氧化处理技术被公认为是处理水环境中有机污染物最具潜力的绿色方法之一。同时,“以废治废”逐渐成为“碳中和”背景下对污染治理的新要求,为提高环境治理水平和社会可持续发展能力,利用生物废弃物等转化为生物炭已成为当前研究热点。利用生物炭具有比表面积易调控、导电性能好以及表面官能团丰富等优势,将光催化氧化与生物炭吸附进行功能协同是一种极具发展前景的有机污染物去除研究体系。概括了生物炭/光催化复合材料的制备方法与工艺,分析了复合材料中生物炭和光催化材料二者功能间的相互影响。此外,通过阐述生物炭/光催化复合材料对污染物的去除过程,深入探讨了吸附-光降解的整体作用机制,并梳理了国内外针对最新重点管控新污染物清单的相关研究进展。最后针对复合材料界面关系、电子迁移性质、综合水体应用等方面,对生物炭/光催化复合材料提出了相关讨论和未来建议。
Advanced oxidation technology based on photocatalytic materials is widely recognized as a leading green method for effectively treating organic pollutants in aquatic environments.In the current era of“carbon neutrality”,the concept of“waste for waste”has emerged as a new imperative in pollution management.This trend underscores the importance of leveraging resources like bio-waste to produce biochar,thereby enhancing environmental management standards and promoting sustainable societal development.The integration of biochar′s unique surface modification capabilities,excellent electrical conductivity,and abundant surface functional groups with photocatalytic oxidation represents a promising strategy for organic pollutant removal.This article provided an overview of the preparation methods and processes involved in biochar/photocatalytic composite production,examining the functional interplay between biochar and photocatalytic materials within the composites.In addition,the paper delved into the adsorption-photodegradation mechanism,elucidating the pollutant removal process facilitated by biochar/photocatalytic composites and summarizing the latest domestic and international research advancements in managing emerging pollutants.Finally,the study offerd relevant insights,discussions,and future suggestions regarding the interface dynamics,electron migration properties,and integrated water treatment applications of biochar/photocatalytic composites,outlining directions for future research and development.
