“…The band at 891░cm 1 occurs due to deformation of the polymer skeleton. The peak at 805░cm 1 is associated with the deformation of the tri-s-triazine ring (14,9). The IR spectra of CN-Cu and CN-Fe did not show any evident effect of either copper or iron on the characteristic bands, and are similar to the spectrum of CN (9).…”

“…The structure of graphite carbon nitride allows it to interact with ions and polar species, so it is possible to dope this material with fluorine, boron (6), iron (7), copper (8,9), manganese (10), nickel, or cobalt (11). The doping of carbon nitride enhances either the conversion or selectivity of the catalyst (9) by affecting its morphology, its response to visible light and its photocatalytic activity (12).…”

Polymeric carbon nitride was synthesized from urea and doped with Cu and Fe to act as cocatalysts. The material doped with Fe was a new composite material composed of Fe(III) oxides (acting as a co-catalyst) wrapped by the polymer layers and amorphous carbon. Furthermore, the copper doped material was described in a previous report. The photocatalytic degradation of the azo dye direct blue 1 (DB) was studied using as photocatalysts: pure carbon nitride (CN), carbon nitride doped with Cu (CN-Cu), and carbon nitride doped with Fe (CN-Fe). The catalysts were characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), by

“…The FTIR analysis correlates to previous reports on g-C3N4. 32,[45][46][47][48][49][50][51][52] The finger printing from 807 to 1650 cm -1 and from 3100 to 3500 cm -1 by FTIR analysis demonstrates that the materials synthesized are C3N4 structure type ( Figure 2). The peaks at 807 cm −1 are the characteristic breathing mode of the s-triazine ring system.…”

“…Essentially, carbon has two unique bonding configurations (C1, C2) whilst nitrogen adopts four unique configurations (from N1 to N4) in the carbon nitride structure. 45 This causes a splitting in the XPS signal for each configuration allowing investigation of structure. Both elements C and N, in the C3N4 graphitic structure, generate the signal due to the π to π* transition (shake-up) at around 293.8 eV and 404.2 eV respectively, as reported in Table 2.…”

An Investigation into the Stability of Graphitic C₃N₄ as a Photocatalyst for CO₂ Reduction

The increasing CO2 concentration in the atmosphere exerts a significant influence on global warming and climate change. The capture and utilization of CO2 by conversion to useful products is an area of active research. In this work, the photo-driven reduction of CO2 was investigated using graphitic carbon nitride (g-C3N4) as a potential photocatalyst. The photocatalytic reduction of CO2 was investigated with g-C3N4 powder immobilized on a glass support in a batch gas phase photoreactor. The experiments were carried out under UV-Vis irradiation at 70°C and an initial pressure of 2.5 bar. The only gas phase product detected during the irradiation of the g-C3N4 in the presence of CO2 was CO, and the rate of production was observed to decrease over time. Oxygen doped g-C3N4 was also tested for CO2 reduction but had lower efficiency that the parent g-C3N4. Repeated cycles of photocatalytic CO2 reduction showed a decline in the activity of the g-C3N4. In the absence of CO2 some CO generation was also observed. Characterization of used and unused materials, using FTIR and XPS, showed an increase in the oxygen functional groups following UV-Vis irradiation or thermal treatment. While others report the use of g-C3N4 as a photocatalyst, this work highlights the important need for replicates and control testing to determine material stability.
