Well-crystallized Nitrogen-rich Graphitic Carbon Nitride Nanocrystallites Prepared Via Solvothermal Route At Low Temperature

摘要

A solvothermal method has been successfully applied to prepare crystalline carbon nitride from C_3N_3Cl_3 and NaN_3 in CCl_4 at 180 C without any catalyst. The final product was a reddish brown powder. X-ray diffraction pattern indicated that the prepared powder was well-crystallized graphitic carbon nitride. The atomic N/C ratio determined by combustion method was 1.63, indicating a high nitrogen concentration. XPS and FTIR studies showed that graphite-like sp~2 bonded structure existed in the sample. Nanometer scale spherical particles and crinkly lamellas were found in the TEM morphologies.
