Effect of submicron particles of anthracite on the conditions of aerosol synthesis and properties of carbon nanotubes

The properties of single-walled carbon nanotubes (SWCNTs) obtained by the floating catalyst CVD method using ethyl alcohol and coal particles (anthracite and semi-anthracite) were studied. The structural and vibrational characteristics of the synthesis products are determined. It was found that the enrichment of the reaction mixture with anthracite particles increases the concentration of CO and CH4 in the reaction zone, which contributes to the growth of SWCNTs. Comparison of the Raman spectra shows an increase in the content of small-diameter semiconducting SWCNTs, while the set of chirality indices of the resulting nanotubes remains unchanged.
