New method for synthesis of oxygen-doped graphite-like carbon nitride from pyridine

New method for synthesis of oxygen-doped graphite-like carbon nitride from pyridine Simple method for single-stage synthesis of O-doped carbon nitride (O-C3N) with a C/N ratio of 3.46 and high content of oxygen (11.1 wt %) is suggested. Carbon nitride is formed in the reaction flow of pyridine pyrolysis products, carried by this flow away from the high-temperature (1050°C) reaction zone, and localized in the low-temperature (<70°C)zone of the reaction space. The mass spectra of the thermolysis products of the thus synthesized O-C3N show not only molecules (HCN, C2N2, and CO) and nitrogen-carbon fragments (CN+, C4N2 +, and C2N+), but also carbon and nitrogen atoms.

Abstract

Simple method for single-stage synthesis of O-doped carbon nitride (O-C3N) with a C/N ratio of 3.46 and high content of oxygen (11.1 wt %) is suggested. Carbon nitride is formed in the reaction flow of pyridine pyrolysis products, carried by this flow away from the high-temperature (1050°C) reaction zone, and localized in the low-temperature (<70°C)zone of the reaction space. The mass spectra of the thermolysis products of the thus synthesized O-C3N show not only molecules (HCN, C2N2, and CO) and nitrogen-carbon fragments (CN+, C4N2 +, and C2N+), but also carbon and nitrogen atoms. O-C3N x was studied by the methods of X-ray diffraction and chemical analyses, temperature-programmed desorption/mass spectrometry, and IR and XPS spectroscopies.
