摘要
生物炭是生物质热解和碳化后产生的高含碳物质。氮掺杂生物炭改善了生物炭的性能,使其在吸附降解有机污染物等方面的应用前景更为可观,引起了学者的广泛关注。而氮掺杂生物炭对有机污染物的吸附降解性能受多种因素影响,如生物炭的制备条件及其性质等。详细讨论了生物质原料和掺杂方式等因素对氮掺杂生物炭性质的影响,总结了氮掺杂生物炭吸附和降解有机污染物的影响因素及机理,并提出了氮掺杂生物炭的未来研究方向。
Biochar is a carbonaceous substance produced with pyrolysis and carbonization of biomass.Nitrogen doped biochar improves the performance of biochar and has a more promising application prospect in the adsorption and degradation of organic pollutants,which has attracted extensive attention of scholars.The adsorption and degradation performance of nitrogen doped biochar for organic pollutants is affected by many factors,such as the preparation conditions and properties of biochar.This paper discusses in detail the effects of biomass raw materials and doping methods on the properties of nitrogen doped biochar,reveals the influencing factors and mechanism of its adsorption and degradation properties for organic pollutants,and puts forward the future research direction of nitrogen doped biochar.
