In Situ Prepared NRCPFs as Highly Active Photo Platforms for in Situ Bond Formation Between Aryldiazonium Salts and Heteroarenes

Abstract

Covalent perylene frameworks (CPFs) with melamine linkages have newly received rising interest for a variety of applications because of nitrogen‐rich content and high stability. Herein, we account a new simple strategy to in situ attain nitrogen‐rich covalent perylene frameworks (NRCPFs) as highly active photo platforms for in situ bond formation between aryldiazonium salts and heteroarenes (C–H bond arylation) through the controlled photoredox route.

Photocatalytic oxygenation of sulfide using solar light and ingenious GQDs@AQ catalyst: Mechanistic and synthetic investigations

“…The zeta potential (ZP) and particle size (PS) were observed through the dynamic light scattering (DLS) technique. The ZP value of GQDs@AQ photocatalyst (−26.9 eV) is less positive than GQDs (−24.1 eV), which designates that the attachment of highly efficient GQDs with AQ as per described literature routes 27–29 . From the same technique, we measured the PS of the GQDs and GQDs@AQ photocatalyst (Figure 3), respectively.…”

“…30 There are various issues such as strains, defects, and coupling, which distress the position of the D and G bands. 29 However, it should be distinguished that both bands are shifting due to the generation of new amide bond groups and these changes are improved with an increase in the atomic ratio of N-C atomic in GQDs@AQ photocatalyst. 30,31…”

Supercharging green chemistry: Unleashing 1, 4‐NADH regeneration and unprecedented C(sp3)‐F bond activation via NiS‐NiO/S‐g‐C3N4 nanocomposite photocatalyst under solar light

“…These two variables, when combined, lead to the enhanced efficiency of the NiS‐NiO/S‐g‐C 3 N 4 nanocomposite photocatalyst for photocatalytic processes when compared to S‐g‐C 3 N 4 . Smaller particle size and a quicker charge transfer rate can result in improved photocatalytic activity, making the NiS‐NiO/S‐g‐C 3 N 4 nanocomposite photocatalyst a better choice for certain applications 44,45 …”

“…Smaller particle size and a quicker charge transfer rate can result in improved photocatalytic activity, making the NiS-NiO/S-g-C 3 N 4 nanocomposite photocatalyst a better choice for certain applications. 44,45 The zeta potential is a useful measure for determining the surface charge of particles or materials in a colloidal system. It can provide information regarding the stability of colloidal dispersions as well as insights into material surface characteristics.…”
