在微波等离子体条件下,以乙炔炭黑/二茂铁为原料,低温合成纳米洋葱状富勒烯(Nano-structured Onion-like Fullerenes:NSOFs).采用HRTEM、Raman和XRD等分析方法对产物的形貌、尺寸、微观结构及其物相结构进行了表征.结果表明,以乙炔炭黑/二茂铁为原料可大量合成NSOFs,其外观呈准球状或多面体状、实心、直径分布均匀,最外碳层由闭合的、呈波浪状的石墨片构成.
Nano-structured onion-like fullerenes (NSOFs) were synthesized from C2H2 carbon black/ferrocene by microwave plasma. High resolution transmission electron microscope (HRTEM), Raman and X-ray diffraction (XRD) techniques were used to characterize the morphologies and structures of the products. Results indicated that NSOFs could be prepared from C2H2 carbon black/ferrocene. The particles displayed a clear polyhedral or spherical morphology, with cores and waving out layers.
