Graphitic carbon nitride: Synthesis, characterization and photocatalytic decomposition of nitrous oxide
Original language description
Graphitic carbon nitride (g-C3N4) was synthetized by condensation of melamine at the temperatures of 400-700 oC in air for 2 hours and resulting products were characterized and finally tested for the photocatalytic decomposition of nitrous oxide. The characterization methods were elemental analysis, UV-Vis diffuse reflectance spectroscopy, photoluminescence, Fourier transform infrared (FTIR) and Raman spectroscopy, measurement of specific surface area, X-ray powder diffraction (XRD), scanning and transmission electron microscopy. The XRD patterns, FTIR and Raman spectra proved the presence of g-C3N4 at above 550 oC but the optimal synthesis temperature of 600-650 oC was found. Under these conditions graphitic carbon nitride of the overall empirical composition of C6N9H2 was formed. At lower temperatures g-C3N4 with a higher content of hydrogen was formed but at higher temperatures g-C3N4 was decomposed. At the temperatures above 650 oC, its exfoliation was observed. The photocatalytic experiments showed that the activity of all the samples synthetized at 400-700 oC was very similar, that is, within the range of experimental error (5 %). The total conversion of N2O reached about 43 % after 14 hours.
