Abstract

Graphitic carbon nitride (g-C3N4) has been proposed as a promising two-dimensional semiconducting materials and has shown the various applications in the field of photocatalyst due to its thermally stable and...

Ultrasonic-assisted synthesis of porous S-doped carbon nitride ribbons for photocatalytic reduction of CO2

“…Traditional graphitic carbon nitrides (GCN) made by direct calcination of precursors, on the other hand, are constantly constrained by their bulky structure, uncontrolled band gap, and rapid charge carrier recombination, which limits the active species and useful catalytic sites [10] . Several strategies have recently been devised to enhance the performance of bare GCN, including doping with non-metal [11] , [12] or metal elements [13] , [14] , as well as creating composites with other semiconductors [15] , [16] . However, when exposed to people and the environment, carbon nitrides that have been doped with metals like Zn, Cu, Pb, Ni, etc.…”

Solar light‐assisted rod‐shaped CPTF @ FACC photocatalyst: An efficient platform for oxygenation reactions and coenzymes regeneration

“…1 The solar energy conversion via mimicking natural photosynthesis route is an efficient pathway that develops a sustainable artificial system for coenzyme's regeneration that is, reduced form of nicotinamide adenine dinucleotide (NADH) or its phosphorylated form (NADPH). [27][28][29][30][31] The regenerated coenzyme's act as a hydrogen and electron donor in solar energy-based enzymatic reactions. [32][33][34] However, the high cost of coenzyme's preventing the production of novel energy in the field of industrial enzymatic application, this is because NADH/NADPH itself oxidized into NAD + /NADP + during the enzymatic reaction.…”

“…Moreover, solar light‐assisted artificial photocatalysis is broadly employed in the field of energy conversion and storage 1 . The solar energy conversion via mimicking natural photosynthesis route is an efficient pathway that develops a sustainable artificial system for coenzyme's regeneration that is, reduced form of nicotinamide adenine dinucleotide (NADH) or its phosphorylated form (NADPH) 27‐31 . The regenerated coenzyme's act as a hydrogen and electron donor in solar energy‐based enzymatic reactions 32‐34 .…”

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

“…5,14 Hence, g-C 3 N 4 -based photocatalysts are most useful in applications such as separation and gas storage, 15 sensing, catalysis, energy storage, and optoelectronics. 16–19 Various light-harvesting materials, including organic dye-based polymeric materials, 20,21 nitrogen-containing polymeric materials, and polymer-based nanomaterials, have been investigated for catalytic reactions. 4,22–25 Nitrogen-containing polymeric materials have garnered considerable attention due to their excellent solar light-harvesting photocatalytic ability compared with other, more expensive materials, and chemical stability and extraordinary biocompatibility.…”
