摘要
通过生物质废弃物资源化利用构建氮掺杂生物炭不仅符合绿色化学理念,而且在储能和环境治理方面具有较好的应用前景,其中前驱体类型是高性能氮掺杂生物炭合成的关键.壳聚糖作为自然界唯一富含氨基官能团的多糖分子是优异的氮掺杂生物炭前驱体,惰性气氛下基于热化学过程可在生物炭中实现原位氮掺杂.综述了壳聚糖基氮掺杂生物炭的制备方法及其在超级电容器、电催化、碳捕集和水处理方面的应用研究进展,分析了生物炭比表面积、孔径结构和含氮官能团等因素对其应用性能的影响,论述了壳聚糖基氮掺杂生物炭应用在不同领域的特性优势及面临的主要问题,可为构建高性能氮掺杂生物炭及拓展其潜在应用领域提供一定参考.
Abstract
Transformation of biowaste into N-doped biochar conforms to a concept of green chemistry and also shows good prospects in energy storage and environmental governance.Among them,the precursor type is the key point for the production of high-performance nitrogen-doped biochar.Chitosan,as the only sole polysaccharide with amine-based groups in nature,is an excellent precursor for nitrogen-doped biochar.In situ N-doped can be achieved in biochar through a thermo-chemical process under inert atmosphere.Recent developments on preparation methods of chitosan-based nitrogen-doped biochar and its applications,including supercapacitor,electro-catalysis,CO2 capture and water treatment,were discussed.The effects of surface areas,pore structures and nitrogen-containing functional groups of biochar on the application performances were analyzed.The characteristics,advantages and key issues faced in practical applications of nitrogen-doped biochar were discussed.It can provide certain references for designing high-performance nitrogen-doped biochar and broadening its potential applications.
