层状双氢氧化物-生物炭复合材料在废水处理中的应用

Application of layered double hydroxide-biochar composite in wastewater treatment

层状双氢氧化物-生物炭(LDH-BC)复合材料,作为一种新型生物炭基复合纳米材料,在废水处理中展现了优异的污染物吸附和催化降解性能。本篇综述全面系统地总结LDH-BC复合材料的相关研究进展,为日后研究方向提供指导。研究内容综述了LDH-BC复合材料合成方法,改性策略和复合材料在废水处理中的应用及机制。展望部分提出LDH-BC复合材料存在具体组分降解路径不清晰、复合污染物体系应用较少、缺少现场规模试验等问题,接下来应针对以上问题进行深化拓展以推动LDH-BC复合材料的研究与应用。

Layered double hydroxide-biochar(LDH-BC)composites,novel biochar-based composite nanomaterials that have been shown to be highly effective in adsorbing pollutants and catalyzing degradation in wastewater treatment.This review provides a thorough and organized overview of the current research on LDH-BC composites,which can be used to inform future studies.The research content provides a summary of the synthesis method of LDH-BC composites,the modification strategy,and the application and mechanism of the composites in wastewater treatment.It is suggested in the outlook section that LDH-BC composites have problems inadequate research such as unclear degradation paths of specific components,less application of composite pollutant systems,and lack of field scale tests.The next step is to explore the above shortages of research further in order to promote the research and application of LDH-BC composites.
