A Possible New C-N Phase Originated from Graphitic Carbon Nitride Loaded by Shock Wave
A possible new phase of carbon nitride was synthesized by shock wave using a precursor of mixture of graphitic carbon nitride (g-C3N4) with iron powder in a weight ratio of 10:90 at the flyer velocity of about 3.0 km/s driven by explosive detonation. The results of XRD and TEM indicate that the new phase possesses four weak diffraction peaks at 2=36.06 (d=2.489Å), 41.90(d=2.154Å), 60.88(d=1.520Å) and 72.98(d=1.295Å) besides a strong diffraction peak of graphitic carbon nitride at 2=27.70 (3.218 Å) and shows a few tube-like structures in a diameter of about 200300nm and in a length of about 10003000nm with the exclusive element composition of carbon and nitrogen identified by EDX characterization.
