800℃下在氩气中分解甲烷合成单壁碳纳米管反应中水的作用

摘要

@@ The effects of H2O to synthesizing SWCNTs by decomposing CH4 in Ar at 800℃ were studied by TEM and Raman scattering. It is shown that the water induced into the reacting gas (the relative humidity is about 5% at room temperature)increased the percentage composition of the SWCNTs in products. Preliminary analyses indicate that the water is involved in the purification course of the SWCNTs.
