Efficient carbon nanotube sponges production boosted by acetone in CVD-Synthesis

A high production of nitrogen-doped carbon nanotube sponges (N-CNS) was obtained at 1020 °C with 4 h of growth in an aerosol-assisted chemical vapor deposition experiment modified with two independent sprayers feeding the reactor. Sprayer-1 contained a solution made of benzylamine, ferrocene, and thiophene; sprayer-2 contained a solution made of ethanol-acetone, ferrocene, and thiophene. N-CNS is more thermally stable than nitrogen-doped and undoped MWCNTs and they are super hydrophobic with interesting solvent absorption properties.336
