Recent advances in visible-light graphitic carbon nitride (g-C₃N₄) photocatalysts for chemical transformations

Abstract

Graphitic carbon nitride (g-C3N4) has emerged as a new research hotspot, attracting broad interdisciplinary attention in the form of metal-free and visible-light-responsive photocatalysts.

Synthesis and characterization of CuO@S-doped g-C3N4 based nanocomposites for binder-free sensor applications

“…54,55 This overall analysis is in line with previous reports. 19,40,[51][52][53] Cu 2p, 3s and 3p peaks were clearly detected for the CuO@Sdoped g-C 3 N 4 NC and pure CuO samples in Fig. 9c and d.…”

“…15 Scientific research to improve the structures, precursor effects, band gap, poor visible light absorption, high electron–hole pair recombination and low surface area of g-C 3 N 4 is ongoing. 16–20…”

“…15 Scientic research to improve the structures, precursor effects, band gap, poor visible light absorption, high electron-hole pair recombination and low surface area of g-C 3 N 4 is ongoing. [16][17][18][19][20] Up to date most groundbreaking research studies focused on modifying the inherent and morphological characteristics of g-C 3 N 4 -based nanomaterials in the context of powder suspensions for articial photosynthesis and environmental remediation. However, a detailed study of the synergistic effect of g-C 3 N 4 and dopants (metals, nonmetals, and metal oxides), which is crucial for improving its activity, reveals its own challenge as visible-light-responsive photocatalyst.…”

“…22 Thus computational techniques have been applied for the study of Sdoped g-C 3 N 4 14,23 and P-doped g-C 3 N 4 . 11,24 Even though there are ongoing efforts to enhance the performance of g-C 3 N 4 for multifunctional applications, 19,20,[25][26][27][28] there is still a need for precise and reliable information on the full structural characterization, pore sizes, morphology, crystallinity, photoluminescence, formation energy, charge analysis, band gap, environmental applications and other features of S-doped g-C 3 N 4 based NCs. Therefore, we hereby report a straightforward procedure for producing CuO@S-doped g-C 3 N 4 semiconducting hetero-structured NCs.…”

Visible light-induced photoredox catalyzed C–N coupling of amides with alcohols

“…35–37 a – d In presence of visible light, an organo-photoredox catalyst has the unique ability to activate air oxygen, a green and natural oxidizing agent, for organic reactions involving SET. 38,39 On the basis of above mentioned previous work, related studies on C–N coupling and in continuation of our work 40–58 on visible light induced photoredox catalysed synthesis, we have proposed eosin Y catalyzed visible-light-induced synthetic protocol for the formation C–N bond in N -monoalkylated product from easily available benzamides and benzyl alcohol (Scheme 1). To the best of our knowledge, this is the first example of photoredox catalysis for the synthesis of N -benzylbenzamide.…”
