摘要
近年来,光催化技术成为处理水中有机污染物的有效途径之一。木质素基生物炭载光催化复合材料将木质素基碳材料作为光催化剂载体,通过吸附-光催化联用技术降解水体有机污染物,展现出良好的应用前景。木质素基碳材料的结构和理化性质可以提高光催化剂的吸光性能、降解活性、可分离性和稳定性。本文结合近年来木质素基生物炭载光催化复合材料在降解水体中有机污染物方面的研究成果,介绍了复合材料中碳载体类型、复合材料制备和改性方法以及对废水有机污染物的降解机理,最后对复合材料在染料、抗生素、酚类等典型污染物中的应用及研究进展进行了总结及展望。
In recent years,photocatalytic technology has become one of the effective ways to treat organic pollutants in wastewater.Ligninbased biochar materials were used as photocatalyst carriers to degrade organic pollutants by the combined adsorption and photocatalytic tech⁃nology,showing good application prospects.The structural and physicochemical properties of lignin-based biochar materials could improve the light absorption,degradation activity,separability,and stability of photocatalysts.Therefore,this paper highlighted the types of biochar carriers and the methods of preparation and modification of the material,and emphasized the degradation mechanisms of organic pollutants in wastewater.Finally,the application and research progress of the composites for typical pollutants such as dyes,antibiotics,and phenols were summarized.
