中文摘要: |
近年来,生物炭在环境修复、固碳、土壤改良等方面的得到广泛应用,与纳米材料联合制备的新型生物炭纳米复合材料使原生生物炭的比表面积、孔隙结构、官能团、催化降解能力等方面都有了较大改善,具有更好的可持续性和高效性,对环境中有机污染物具有良好的去除能力。本文介绍了生物炭纳米复合材料的不同制备工艺,重点阐述了生物炭纳米复合材料对不同环境介质中有机污染物的去除机理及应用,为后续生物炭纳米复合材料在环境修复应用的工程化和商业化提供理论依据和技术参考。 |
英文摘要: |
Biochar has been widely used in environmental remediation, carbon sequestration, soil modification and etc. in recent years. Compared to the primary biochar, biochar nanocomposites, which are made from biochar and nanomaterials, have greatly improved surface area, pore structure, functional groups and ability of catalytic degradation, so they are more sustainable and efficient on removing organic pollutants. This paper introduces different preparation processes of biochar nanocomposites systematically and emphasizes the mechanism and application of biochar nanocomposites in the removal of organic pollutants in different environmental media. This work may provide some theoretical and technical supports for the engineering and commercialization of biochar nanocomposites in the field of environmental remediation in the future. |
