摘要/Abstract

摘要： 在射频等离子体条件下以煤为原料制备纳米洋葱状富勒烯(Nano-structured Onion—like Fullerenes:NSOFs).高分辨透射电镜(HRTEM)和X射线衍射(XRD)表征结果表明:以煤为原料可大量制备NSOFs,纯度较高,无碳纳米管伴随生成,外观呈准球状或多面体状,内中空,直径分布较均匀,石墨化程度很高,为低成本合成纯净的NSOFs提供了一条新途径.

关键词: 纳米洋葱状富勒烯, 射频等离子体, 煤, HRTEM

Abstract: Nano-structured onion-like fullerenes (NSOFs) was synthesized from coal by radio frequency plasma. High resolution transmission electron microscope (HRTEM) and X-ray diffraction(XRD) techniques were used to characterize the morphologies and structures of the products. Results indicate that NSOFs can be prepared from coal with high yield. The highly graphitized products contain no carbon nanotubes, the particles display a clear polyhedral or quasi-spherical morphology with hollow center and the method described here might be used to synthesize pure NBOFs at low costs.

Key words: nano-structured onion-like fullerenes, radio frequency plasma, coal, HRTEM
