Formation of Multilayer Carbon Nanotubes from Plant Raw Material for Modification of Carbon-Containing Refractories

Promising technology is presented for obtaining multilayer carbon nanotubes from renewable plant raw material: Sphagnum moss and Katerina SV strain maize waste. It is shown that with mechanochemical treatment of amorphous carbon, synthesized by pyrolysis from brown Sphagnum, there is formation of carbon nanotubes. The yield of nanotubes is from 19 wt.% after 7 h mechanical activation and up to 75 wt.% after 27 h. With treatment of amorphous carbon obtained from maize waste the yield of nanotubes with the same mechanical treatment duration is 11 and 42 wt.%.
