Preparation of sphere-shaped nanoscale carbon nitride polymer

The carbon nitride polymer of the previously unknown sphere-shaped structure was prepared both by a template-directed solid-state and solution phase syntheses from cyanuric chloride or fluoride and lithium nitride. The obtained polymer powder was characterized by SEM/EDAX, TEM, XRD, TGA, XPS, (C-13) MAS NMR, LD/MS, FTIR. UV-visible, and Raman spectroscopy. Modification of the surface area of the template used demonstrated the possibility of producing the carbon nitride spheres with the particle sizes ranging from 20 pm to 50 nm. According to TEM data, the spheres are hollow and the material is shown to be essentially amorphous by powder XRD.
