摘　　要：生物炭具有碳含量高、比表面积大、孔结构发达和吸附性能好的优点,其在土壤质量改良、环境污染修复和固碳减排等领域应用广泛。针对生物炭自身体积密度小、固液分离难及长效性和稳定性亟待进一步提高等实际问题,将生物炭与金属材料、光催化剂和黏土矿物等结合,制备对污染环境具有更高修复效能的生物炭复合材料备受关注。通过系统综述生物炭基复合修复材料的制备方法及环境污染控制应用,分析了其对环境中有机污染物的去除机理,提出了生物炭材料的未来研发趋势,以期为高效生物炭基复合修复材料制备及其实际应用提供新思路。Biochar has the advantages of high carbon content,large specific surface area,well-developed pore structure and good adsorption performance.It is widely used in the fields of soil quality improvement,environmental pollution remediation,carbon sequestration and emission reduction.In view of the practical problems such as low volume density of biochar itself,difficulty in solid-liquid separation,and urgent need to further improve its long-term effectiveness and stability,the biochar composites with higher remediation efficiency for polluted environment were prepared by combining biochar with metal materials,photocatalysts and clay minerals,which attracted much attention.Through a systematic review of the preparation methods and environmental pollution control applications of biochar-based composite materials,and the removal mechanism of organic pollutants in the environment was analyzed,and the future research and development trend of biochar materials was put forward,so as to provide new ideas for the preparation and practical application of high-efficiency biochar composite materials.
