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.The effects of H2O to synthesizing SWCNTs by decomposing CH4 in Ar at 800℃ were studied by TEM and Raman scattering.
