“…An-g-C 3 N 4 composite exhibited more negative value in comparison to DCA, which were attributed to the stability of synthesized complex due to the formation of triazine ring. 42,43 The morphological character of DCA and An-g-C 3 N 4 composite was investigated by using field emission scanning electron microscopy (FESEM). Figure 5 shows the FESEM images of DCA and An-g-C 3 N 4 composite.…”

Direct conversion of sunlight into value-added chemicals through artificial photosynthesis has been recognized as one of the most promising ways to address the global energy needs and to utilize the sustainable energy source. Even though the various semiconducting materials have been used for the solardriven production of chemicals, many experimental efforts have been still focusing on developing clean and reusable photocatalysts. In this study, we report the new metal-free graphitic carbon nitride (g-C 3 N 4 ) composite including anthracene moieties as a primary photosensitizer. The morphological and electronic structure of anthracene-based g-C 3 N 4 (An-g-C 3 N 4 ) composite were characterized by optical spectroscopies, electrochemical measurements, and theoretical calculations based on density-functional theory. The An-g-C 3 N 4 composite exhibited outstanding photocatalytic efficiency for the regenerations of NAD(P)H cofactors owing to the prominent charge-transferred character and the superb light absorption. This study demonstrates that the catalytic reaction employing the combination of An-g-C 3 N 4 photocatalyst and Z-scheme nature would be a suitable option for artificial photosynthesis.

“…Sunlight is a major source of energy on this earth which is used by plants in the formation of glucose by using carbon dioxide (17). Photocatalysts are working in the same manner in artificial photosynthesis using solar energy by converting NAD + into NADH and helping in CO 2 reduction (18,19). At the same time, researchers are utilizing this for solar fuel production (20) that ultimately stabilizes climate change.…”

To meet the energy demands artificial photosynthesis is playing the most promising role these days. Using sunlight directly in a manner that can provide useful chemicals is a sustainable means of generating energy. Studies are going on in this context to make better and effective photocatalyst. In this paper, we study the synthesis of flower-like graphene quantum dots-based fuschin (GQDF) photocatalyst from lemon , which is created by a green and sustainable process that is effective and environment friendly. The UV-visible spectra of prepared GQDF showed a high molar extinction coefficient. A flower-like GQDF photocatalyst has better catalytic efficiency for the selective creation and regeneration of the NAD(P)H cofactor. A newly designed flower-like GQDF photocatalyst is used as one of its most effective photocatalysts as they have several additional applications in the removal of CO 2 and aqueous contaminants like heavy metals.

“…Also, the optical properties of nanostructures are now being explored to facilitate photochemical NADH regeneration. [52][53][54][55] Through electrochemical methods, NADH is regenerated by the reduction of NAD + in a buffer solution at cathodic potentials on an electrode. It has advantages such as use of clean and renewable electrical energy and easy product isolation.…”

NAD is a cofactor that maintains cellular redox homeostasis and has immense industrial and biological significance. It acts as an enzymatic mediator in several biocatalytic electrochemical reactions and undergoes oxidation/reduction to form NAD + or NADH, respectively. The NAD redox couple (NAD + /NADH) mostly exists in enzyme-assisted metabolic reactions as a coenzyme during which electrons and protons are transferred. NADH shuttles these charges between the enzyme and the substrate. In order to understand such complex metabolic reactions, it is vital to study the bio-electrochemistry of NADH. In addition, the regeneration of NADH in industries has attracted significant attention due to its vast usage and high cost. To make biocatalysis economically viable, primary methods of NADH regeneration including enzymatic, chemical, photochemical and electrochemical methods are widely used. This review is mainly focused on the electrochemical reduction of NAD + to NADH with specific details on the mechanism and kinetics of the reaction. It provides emphasis on the different routes (direct and mediated) to electrochemically regenerate NADH from NAD + highlighting the NAD dimer formation. Also, it describes the electrocatalysts developed until now and the scope for development in this area of research.
