Rational design of a graphitic carbon nitride catalytic–biocatalytic system as a photocatalytic platform for solar fine chemical production from CO₂

Abstract

Solar light harvesting artificial nitrogen in-rich polymers with enhanced stability and unmitigated π-conjugation structure are highly enviable. Here we report that generating (formic acid) and regenerating (NADH/NADPH) from CO2 and...

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

“…The optical band gap of NiS‐NiO/S‐g‐C 3 N 4 nanocomposite photocatalysts was also confirmed using Tauc plot (shown in inset Figure 1). The suitability of the optical band gap of the NiS‐NiO/S‐g‐C 3 N 4 nanocomposite photocatalysts performs excellent result in the visible light for C(sp 3 )‐F bond activation and regeneration of selective 1,4‐NADH 37,40 . Furthermore, the NiS‐NiO/S‐g‐C 3 N 4 nanocomposite photocatalysts exhibit outstanding performance in visible light for the activation of C(sp 3 )‐F bonds and the regeneration of selective 1, 4‐NADH.…”

This NiS-NiO/S-g-C 3 N 4 nanocomposite photocatalyst is composed of three different materials: sulfur-doped graphitic carbon nitride (S-g-C 3 N 4 ), nickel sulfide (NiS), and nickel oxide (NiO).…”

Solar-powered CO2 marvel: ultrahigh graphene quantum dots covalently coupled with PhS unleash effective photocatalysis for valuable chemical transformation

“…By the absorption of UV-visible light (PhS), the changes occur in the localized orbitals around the chromophores, resulting in the production of electrons, which further transfer to the rhodium complex via GQDs. 16 Now, this reduced rhodium complex extracts the proton and transfers the electron and the proton to the NAD + , 17 therefore resulting in 1,4-NADH production. Here, the rhodium complex behaves as an electron mediator.…”

Aloe vera‐derived graphene‐coupled phenosafranin photocatalyst for generation and regeneration of ammonia and NADH by mimicking natural photosynthetic route

“…In aqueous SPB solution, the cationic form of ORC can be hydrolyzed readily. This prompt action generates a water-coupled ORC intermediate (A), which relates with anion (HCOO − ) 49,50 to yield an intermediate (B) by losing CO 2 . This mechanism leads to generation of an intermediate of the ORC (C), succeeded by reductive elimination to generate a complex (D).…”
