Carbon Micro/Nano Spring Structures in the Absence of Sulphurous Promoter by CCVD Method
Abstract:Carbon microcoils are generally prepared by catalytic chemical vapor deposition of acetylene, using Ni as the catalyst and thiophene as the promoter. In this work, a new catalyst has been developed on purpose to avoid the introducing of noxious and unpleasant thiophene during the reaction process. The products obtained at temperature of 740 °C were pure, regular and had perfect morphology. Scanning electron microscopy and Raman spectroscopy were employed to characterize the asprepared carbon microcoils.
