“…Compared with Nafion, the g−CN film blended by PEDOT-PSS showed superior PEC activities because the PEDOT-PSS binder is a wonderful conducting polymer and can act as a hole-transport layer. Recently, Tejasvi et al [ 95 ] synthesized stoichiometric g−CN thin films by radio frequency magnetron sputtering using a g−CN pellet as a target. Thin-film samples can be deposited on the borosilicate glass and TiO 2 nanotube array in Ar and N 2 plasma media.…”

“…Some other ex situ methods have also been developed to fabricate g−CN electrodes successfully, including anodic aluminum oxide (AAO) membrane deposition [90], direct growth [61], vacuum filtration deposition [91,92], electrospinning (ESP) [77], vacuum magnetic filtered arc ion plating (VMFAIP) [93], ionothermal (molten salt) deposition [94], radio frequency magnetron (RFM)−based sputtering [95], and so on. A microcontactprinting process was reported by Liu et al, who fabricated g−CN nanostructures by injecting cyanamide into an anodized aluminum oxide (AAO) membrane sandwiched between two substrates and subsequently calcinating at 550 • C for 4 h (Figure 8a).…”

Graphitic carbon nitride (g−CN), a promising visible-light-responsive semiconductor material, is regarded as a fascinating photocatalyst and heterogeneous catalyst for various reactions due to its non-toxicity, high thermal durability and chemical durability, and “earth-abundant” nature. However, practical applications of g−CN in photoelectrochemical (PEC) and photoelectronic devices are still in the early stages of development due to the difficulties in fabricating high-quality g−CN layers on substrates, wide band gaps, high charge-recombination rates, and low electronic conductivity. Various fabrication and modification strategies of g−CN-based films have been reported. This review summarizes the latest progress related to the growth and modification of high-quality g−CN-based films. Furthermore, (1) the classification of synthetic pathways for the preparation of g−CN films, (2) functionalization of g−CN films at an atomic level (elemental doping) and molecular level (copolymerization), (3) modification of g−CN films with a co-catalyst, and (4) composite films fabricating, will be discussed in detail. Last but not least, this review will conclude with a summary and some invigorating viewpoints on the key challenges and future developments.

The efficient monitoring of the environment is currently gaining a continuous growing interest in view of finding solutions for the global pollution issues and their associated climate change. In this sense, two-dimensional (2D) materials appear as one of highly attractive routes for the development of efficient sensing devices due, in particular, to the interesting blend of their superlative properties. For instance, graphene (Gr) and graphitic carbon nitride g-C3N4 (g-CN) have specifically attracted great attention in several domains of sensing applications owing to their excellent electronic and physical-chemical properties. Despite the high potential they offer in the development and fabrication of high-performance gas-sensing devices, an exhaustive comparison between Gr and g-CN is not well established yet regarding their electronic properties and their sensing performances such as sensitivity and selectivity. Hence, this work aims at providing a state-of-the-art overview of the latest experimental advances in the fabrication, characterization, development, and implementation of these 2D materials in gas-sensing applications. Then, the reported results are compared to our numerical simulations using density functional theory carried out on the interactions of Gr and g-CN with some selected hazardous gases’ molecules such as NO2, CO2, and HF. Our findings conform with the superior performances of the g-CN regarding HF detection, while both g-CN and Gr show comparable detection performances for the remaining considered gases. This allows suggesting an outlook regarding the future use of these 2D materials as high-performance gas sensors.

“…[33,116,122] Very recently, an original sputtering method using radio frequency magnetron (RFM) was used for the stoichiometric growth of photoactive C 3 N 4 thin films. [123] This method utilizes g-C 3 N 4 powder in the compact form to serve as the sputtering target. The thin-film deposition was carried out on different substrates, including borosilicate glass and TiO 2 nanotubular array, under two different plasma media, i.e., Ar and N 2 at various time durations.…”

Graphitic carbon nitride (g‐C3N4) is a metal‐free semiconductor that has been widely regarded as a promising candidate for sustainable energy production or storage. In recent years, g‐C3N4 has become the center of attention by virtue of its impressive properties, such as being inexpensive, easily fabricable, nontoxic, highly stable, and environment friendly. Herein, the recent research developments related to g‐C3N4 are outlined, which sheds light on its future prospective. Various synthetic methods and their impact on the properties of g‐C3N4 are detailed, along with discussion on frequently used characterization methods. Different approaches for g‐C3N4 surface functionalization, mainly categorized under covalent and noncovalent strategies, are outlined. Moreover, the processing methods of g‐C3N4, such as g‐C3N4‐based thin films, hierarchical, and hybrid structures, are explored. Next, compared with the extensively studied energy‐related applications of the modified g‐C3N4s, relatively less‐examined areas, such as environmental and sensing, are presented. By highlighting the strong potential of these materials and the existing research gaps, new researchers are encouraged to produce functional g‐C3N4‐based materials using diverse surface modification and processing routes.
