“…Graphitic carbon nitride is a well-known organic semiconductor with distinct electronic, optical, and mechanical properties. Therefore, g-N 3 C 4 has high potential to be used in optoelectronic applications, as reported in the literature [ 18 , 19 ]. In the literature, the advantage of using g-N 3 C 4 as a polymer dopant was reported.…”

The present work considers the integration of g-C3N4 nanosheets into PVC/PVP polymer nanocomposites at ratios of 0.0, 0.3, 0.6, and 1.0 wt%. The XRD data scans showed semicrystalline structures for all PVC/PVP/g-C3N4 polymer blend films. The FTIR and Raman measurements revealed intermolecular hydrogen bonding between the g-C3N4 surface and the OH− groups of the PVC/PVP network. ESEM morphology analysis for PVC/PVP/g-C3N4 nanocomposite films displayed homogeneous surface textures. The data of TGA showed improved thermal stability as the decomposition temperature increased from 262 to 276 °C with the content of g-C3N4 (0.0–1.0 wt%). The optical absorbance data for PVC/PVP films improved after the addition of g-C3N4. The optical energy gaps showed compositional dependence on the g-C3N4 content, which changed from 5.23 to 5.34 eV at indirect allowed transitions. The refractive index for these blend films enhanced (1.83–3.96) with the inclusion of g-C3N4. Moreover, the optical susceptibility for these nanocomposite films increased as the content of g-C3N4 changed from 0.0 to 1.0 wt%. Finally, the values of the nonlinear refractive index showed improvement with the increased percentage of g-C3N4. When g-C3N4 was added up to 1.0 wt%, the DC conductivity improved from 4.21 × 10−8 to 1.78 x 10−6 S/cm. The outcomes of this study prove the suitable application of PVC/PVP/g-C3N4 in optoelectronic fiber sensors.

“…For a comprehensive review of the field, we refer the reader to some recent review articles as background reading on CN materials, [7][8][9][10] PEC, 1,4,5 and CN in PEC, [11][12][13][14][15] specifically, the sections describing harnessing CN as the active photoanode component (Figure 1A). Briefly, 2D graphitic CN, in its ideal form, is a polymer based on the tri-striazine unit (heptazine, highlighted in yellow in Figure 1B), with a tertiary amine (pink shading, Figure 1B) connecting three of these units.…”

Polymeric carbon nitride (CN) materials are promising low-cost photocatalysts that exhibit a combination of chemical and physical properties suitable for converting light into redox activity on their surface. In this perspective, we describe our experience with this family of materials as light absorbers that serve as an anode in photoelectrochemical cells toward water-splitting. We describe some of the CN deposition techniques and procedures established in our lab. The knowledge gained from powderbased photocatalysis is implemented in photoelectrochemical scenarios and is used to determine the merits and shortcomings of resulting layers. We show how the preparation methods are oriented based on these factors and how high photoelectrochemical water-splitting activity develops in photoanodes we developed where CN(s) act as photoabsorbers. Lastly, we present our view on the future prospects of this field.

“…26 Unlike graphite, g-C 3 N 4 consists only of covalently-bonded sp 2 -hybridized C and N atoms. 27 g-C 3 N 4 is a promising material in many fields such as photocatalysis, 28 optoelectronics, 29 and sensing 30 applications due to its physicochemical, electronic, and optical properties. 31 In general, bulk g-C 3 N 4 is produced through the pyrolysis of certain precursors such as melamine, dicyandiamide, thiourea, or urea.…”
