Holey cnt synthesis
Nettetgeneration through the nanotube walls. The holey carbon nanotube products exhibited enhanced surface area, pore volume, and oxygen-containing functional groups, which … NettetOriginal accounts of carbon nanotube synthesis are well known for the heterogeneity of reaction products produced (multiwalled species, and for the single walled tubes, mixtures subsequently identified as semiconducting, metallic, and insulating structures) (Iijima, 1991 ). In terms of inner width, SWCNTs possess a range of 2 to 30 nm.
