Controlled synthesis of novel chromium nitride dendritic and bundle-like nanocrystals via solvent-free route at low temperature
By controlling the supersaturation, cubic CrN with novel dendritic and bundle-like nanostructures was synthesized via the solvent-free reaction of CrCl3 and NaNH2 at 250 degrees C. On the basis of the characterization of the obtained products by XRD, XPS, TEM, HRTEM, and FESEM, the possible formation mechanism of CrN with different nanostructures is proposed here.
