Synthesis of carbon nitride nanotubes with the C3N4 stoichiometry via a benzene-thermal process at low temperatures

Abstract

In this communication, we first report the direct synthesis of high-quality carbon nitride nanotubes (CNNTs) with inner diameters of 50–100 nm and wall thicknesses of 20–50 nm with the C₃N₄ stoichiometry on a high-yield of 40% via a simple benzene-thermal process involving the reaction of C₃N₃Cl₃ with NaN₃ in a Teflon-lined autoclave at 220 °C without using any catalyst or template.
