- Abstract
Crystalline carbon nitride nanocones with intact appearances and the minimum apex diameter of 2–3 nm have been grown vertically on Co-covered Si substrates, using the direct-current abnormal glow discharge plasma-assisted chemical vapor deposition method. The abnormal glow discharges for growth of carbon nitride nanocones were carried out in the ambience of mixtures of methane and nitrogen, with a total pressure of 30 Torr and a CH4/N2 pressure ratio of 1/50. Energy-dispersive X-ray spectroscopy and selected-area electron diffraction results indicated that the as-grown carbon nitride nanocones have the atomic [C]:[N] ratio of nearly 3:4 and the crystallinity close to the β-C3N4 structure. Based on the characterizations and analyses for the as-grown carbon nitride nanocones, two main growth ways with different Co-layer thicknesses are presented.
