Graphitic carbon nitride C6N9H3·HCl: Characterisation by UV and near-IR FT Raman spectroscopy

摘要: The graphitic layered compound C6N9H3.HCl was prepared by reaction between melamine and cyanuric chloride under high pressure–high temperature condition in a piston cylinder apparatus characterised using SEM, powderX-ray diffraction, UV Raman near-IR Fourier transform spectroscopy with excitation. Theoretical calculations density functional methods permitted evaluation of the mode attachment H atoms to nitrogen sites structure better understanding X-ray diffraction pattern. Broadening FT spectra indicate possible disordering void within layers or it could be due electron–phonon coupling effects.
