Further studies on microstructural characterization and hydrogenation behaviour of graphitic nanofibres

摘要

The present study is aimed at microstructural characterization and hydrogenation behaviour of graphitic nanofibres (GNF) prepared by ethylene gas. The GNF were prepared by thermal cracking of ethylene gas at a temperature of ～600 deg. C for time durations of 2 h. The structural characterizations have been evaluated by X-ray diffraction and transmission electron microscopy. It was found that the typical length of GNF was in the range of ～1 to ～6 μm and most of GNF sample exhibits coil like configuration.
