Crystalline carbon nitride nanopowders and nanorods have been successfully synthesized at room temperature and pressure using the novel technique of pulsed laser ablation of a graphite target in liquid ammonia solution.The experimental composition and structure of the nanoparticles are consistent with the theoretical calculations for α-C3N4. A formation mechanism for the nanorods is proposed whereby nanoparticles are first synthesized via rapid formation of an embryonic particle, followed by a slow growth phase, eventually leading to formation of a one-dimensional nanorod structure.
