Preparation of Nitrogen‐Rich Nanolayered, Nanoclustered, and Nanodendritic Carbon Nitrides

Only C and N atoms are present in the high-nitrogen compound 4,4′,6,6′-tetra(azido)azo-1,3,5-triazine (TAAT), which is thus an ideal precursor for carbon nitrides. Controlled pyrolysis of TAAT afforded novel nitrogen-rich carbon nitrides in the form of nanolayers (C2N3), nanoclusters (C3N5), and nanodendrites (C3N5, see SEM image). The pyrolyses occur at low temperature and without applied pressure and require no vacuum systems, extraction, carbonization, or purification.
