摘　　要：生物炭在环境修复中具有很大的应用潜力,但是原始生物炭表面的活性位点较少,有必要通过改性提升其活性。金属材料具有良好的催化活性,将其负载到生物炭上,有助于增加生物炭的吸附位点、提升表面活性,促进生物炭对污染物的高效去除。该文梳理了金属负载生物炭材料的制备方法及其对生物炭理化性质的影响,归纳了金属负载生物炭活化过硫酸盐氧化、光催化氧化、电催化氧化、类芬顿技术、臭氧催化氧化、超声催化去除有机污染的催化作用机理,并对未来的研究工作进行了展望,以期为生物炭在环境污染修复中的高效应用提供借鉴。The biochar has shown a great potential in environmental remediation;however,there is fewer active sites in the raw biochar,so the modification is necessary to enhance its activity.Metal materials can be loaded on biochar to increase adsorption sites,improve surface reactivity,and facilitate the efficient removal of pollutants.In this article,the preparation methods of metal loaded biochar and their effects on the physico-chemical properties of biochar were reviewed.In addition,catalytic mechanisms,including persulfate activation,photo-catalytic oxidation,electro-catalytic oxidation,Fenton-like processes,ozone catalytic oxidation and ultrasonic catalysis for the removal of organic pollutants were summarized.Further⁃more,future research in this area is prospected.It is expected that the overview could provide insights for the effective applica⁃tion of biochar in environmental remediation.
