Abstract :
Carbon nitride nanotubes have been rapidly synthesized using high-frequency induction heating equipment in less than 3 minutes. The diameter of synthesized carbon nitride nanotubes is about 1.5-2 nm. Both X-ray photoelectron spectra and EDX analysis give its formula of CN nanotube. The carbon nitride nanotubes grown under this condition have better field-emission characteristics with low turn-on and threshold fields of 1.1 and 3.8 V/mum, respectively. The reason could be that carbon nitride nanotubes synthesized by high-frequency inducting heating with high heating rate have more ldquobamboo-likerdquo structure with many open ends and high purity.
