在这项工作中，我们研究了在控制量的含氯前体和二茂铁的存在下通过化学气相沉积（CVD）方法制备的碳纳米结构的形态和结构特性。我们报告观察到的结构从管状碳纳米管（CNT）的形态到平面的几层石墨在实验中涉及的二茂铁和二氯苯的混合物的热解。当使用中间量的二氯苯时，发现生长的CNT的壁中的不寻常的中间卷曲状机制。通过扫描电子显微镜（SEM）和透射电子显微镜（TEM）研究了这种形貌变化，发现在Fe3C纳米颗粒表面形成了与Fe3C纳米颗粒直接相连的平面少层类石墨烯结构。而通过X射线衍射和拉曼光谱技术分析所获得的结构的结构变化。
In this work, we investigate the morphological and structural properties of carbon nanostructures fabricated by means of chemical vapor deposition (CVD) methods in the presence of controlled quantities of Cl-containing precursor and ferrocene. We report the observation of a structural transition from tubular-like carbon nanotube (CNT) morphology into planar few-layers graphite in experiments involving the pyrolysis of ferrocene and dichlorobenzene mixtures. An unusual intermediate curling-like mechanism in the walls of the as-grown CNTs is found when intermediate quantities of dichlorobenzene are used. This unusual phenomenon vanishes for high quantities of dichlorobenzene, where the nucleation of planar few-layers graphene-like structures directly connected to micrometer-scale Fe3C particles is found. Such morphological variation is investigated by means of both scanning electron microscopy (SEM) and transmission electron microscopy (TEM), whereas the structural variation of the obtained structures is analyzed through X-ray diffraction and Raman spectroscopy techniques.
