摘要：
Single-wall carbon nanohorns (SWCNHs) with different morphologies were generated by direct current arc-discharge between pure graphite rods in different atmospheres, including air, CO2 and CO in the arc-discharge process, the O-2 in the air reacted with carbon atoms and transformed into CO so that the formation of SWCNHs was a result of a combination of CO and N-2 The effect of different volume ratios of CO/N-2 on the formation of SWCNHs was examined and a mechanism for the formation of SWCNHs is proposed (C) 2009 Elsevier Ltd All rights reserved
