“…In recent years, the g-C 3 N 4 nanostructured materials have been studied for CO 2 photoreduction [92,165], due to their excellent stability, sufficiently negative CB energy and narrow band gap. Many strategies are reported to promote g-C 3 N 4 with condensed matter and molecular sensitizers [166,167], such as doping with metals [168,169] and non-metal [170][171][172], heterojunction construction [173][174][175][176] and Z-scheme composites employing co-catalysts [165][166][167]173,175].…”

Graphitic carbon nitride (g-C 3 N 4 ) is a promising material for photocatalytic applications such as solar fuels production through CO 2 reduction and water splitting, and environmental remediation through the degradation of organic pollutants. This promise reflects the advantageous photophysical properties of g-C 3 N 4 nanostructures, notably high surface area, quantum efficiency, interfacial charge separation and transport, and ease of modification through either composite formation or the incorporation of desirable surface functionalities. Here, we review recent progress in the synthesis and photocatalytic applications of diverse g-C 3 N 4 nanostructured materials, and highlight the physical basis underpinning their performance for each application. Potential new architectures, such as hierarchical or composite g-C 3 N 4 nanostructures, that may offer further performance enhancements in solar energy harvesting and conversion are also outlined.

“…After two decades, carbon nitride has established itself as an efficient proton reduction catalyst [7]. Carbon nitride (g-C 3 N 4 ) shows good efficiency on proton reduction in the presence of some co-catalysts such as Ni and Ni-P [8]. In the presence of co-catalyst, carbon nitride even can oxidize water [9].…”

Converting solar energy into storable solar fuels such as H 2 from earth abundant sourcewater-is a nice approach to find the solution of energy crisis and environmental protection. There are two half reactions; first, water oxidation into oxygen and proton and followed by proton reduction led to H 2 evolution from water. After two decades of continuous attempts, there have been several efficient water oxidation photocatalysts introduced, whereas the proton reduction photocatalyst were relatively less explored. Major portion of reported photocatalysts for proton reduction are mainly derived from either noble metals or precious metals. Carbon-based organic photocatalysts have become attractive recently. These organic materials have several advantages like light weight, cheap, well-defined structure-property relationship and the most attractive one is better batch to batch reproducibility. Here, the reported organic photocatalysts and their performance are summarized which in fact help others to get an idea about ongoing progress in this area of research and to understand the basic designing principle for efficient photocatalysts for fuel production.

“…The development of an active, scalable and stable photocatalyst remains one of the biggest challenges in modern day catalysis. Many families of semiconductors have been made and tested including oxide semiconductors such as TiO 2 , ZnO, WO 3 , BiVO 4 , [1][2][3][4] sulfide semiconductors such as CdS, ZnS, Mo x S y , [5][6][7] and nitride semiconductors such as GaN, InGaN, C 3 N 4 [8][9][10]. These semiconductors alone or in mixed forms including solid solutions and abrupt interfaced materials such as layer by layer growth or layer Abstract Both Pd and Au metal particles are used in photocatalytic hydrogen generation.…”
