生物质基碳包覆纳米磁性颗粒的研究进展

Research Advances in Biomass-based Carbon Encapsulated Magnetic Nanoparticles

碳包覆纳米磁性颗粒(CEMNPs)是一种具有核/壳结构的新型纳米复合材料,独特的理化性质使其在众多技术领域显示出巨大的应用潜力。随着全球化石能源的日渐枯竭,利用廉价、易获取、环境友好的生物质原料作为替代碳源已成为近年来CEMNPs材料的研究热点。综述了生物质基CEMNPs的制备方法、反应机理以及在电化学、催化、吸附等领域中的应用,最后展望了其发展方向和趋势。

Carbon encapsulated magnetic nanopartieles （CEMNPs） are regarded as a novel nanocomposite with a core/shell structure, which displays great potential in many technical fields due to their excellent physical and chemical properties. Biomass feedstock has been gradually used for CEMNPs preparation because biomasses are low-cost, easy to obtain and environmental friendly. This paper reviews the preparation methods, corresponding nucleation mechanisms and applications of biomass-based carbon encapsulated magnetic nanoparticles, and the applications in electrochemistry, catalysis and other fields are introduced as well.
