Study on the Synthesis and Photocatalytic Performance of Modified TiO2 Supported by G‐C3N4 in the Degradation of 2,4‐Dichlorophenoxyacetic Acid

“…The pristine g‐C 3 N 4 (Figure 4B) exhibits a single characteristic diffraction peak located at 2‐θ position 27.5°, which corresponds to the (002) plane of the interlayer stacking of conjugated aromatic system of g‐C 3 N 4 (JCPDS Card No. 87–1526) [29, 30] . diffraction peaks of mod.TiO 2 and pristine g‐C 3 N 4 are visible in the XRD patterns for the mod.TiO 2 /g‐C 3 N 4 nanocomposites, indicating the coexistence of these compounds in the composites.…”

“…When stimulated with a suitable light source, [17,29,30] electrons in the valence band (VB) of g‐C 3 N 4 and mod.TiO 2 jump to the conduction bands (CB), resulting in a CB rich in electrons (e − ) and leaving behind in the VB holes (h + ). Due to E CB of g‐C 3 N 4 (− 1.12 eV) is more negative than that of mod.TiO 2 (−0.14 eV) therefore, the generated electrons in the CB of g‐C 3 N 4 can transfer down to the CB of TiO 2 , preventing these electrons (e − ) from recombining with the holes (h + ) in the VB of g‐C 3 N 4 .…”

“…Graphite carbon nitride (g‐C 3 N 4 ), a non‐metallic semiconductor material recently has attracted much attention because of its narrow bandgap (~2.7 eV), good mechanical durability, high chemical stability and being easy biodegradable [29,30] . However, the photocatalytic efficiency of g‐C 3 N 4 is hindered due to its low specific surface area (10–15 m 2 g −1 ) which is insufficient for visible ‐ light absorption, and rapid recombination of photoinduced electron–hole pairs.…”

Charting New Horizons: Unrivalled Efficiency and Stability in Perovskite Solar Cells

“…Other examples of HTLs include Spiro‐OMeTAD, PEDOT:PSS, and copper(I) thiocyanate (CuSCN), among others. [ 27 ]…”

“…Additionally, carbon‐based materials, such as carbon nanotubes (CNTs) or graphene, present opportunities for transparent conductive layers. [ 27,33 ] These alternatives aim to address issues related to material scarcity and enhance the overall sustainability of solar cell technologies. Comprehensive discussions on the advantages, challenges, and optimization strategies associated with the use of Cu, carbon, and other transparent electrodes in TSCs and bifacial solar cells contribute to advancing the field and optimizing next‐generation photovoltaic devices.…”
