“…A g-C 3 N 4 /graphene hybrid for sensing pentachlorophenol (PCP) was synthesized by Xia et al (Figure 10b). [146] As a fixed platform for the g-C 3 N 4 , graphene remarkably enhanced the ECL intensity of g-C 3 N 4 (approximately 4.7-fold). In addition, a coreactant can be produced in situ from oxygen reduction, leading to a further improvement in the ECL signal.…”

In recent years, graphitic carbon nitride (g-C 3 N 4) has attracted much attention due to its unique properties and excellent performance in the field of sensors, which has inspired the authors to compile this review. Although there are many reviews on the synthesis and applications of g-C 3 N 4 materials, a targeted, systematic, comprehensive summary of applications in sensors and the sensing mechanisms of g-C 3 N 4-based nanomaterials have not been published. In this review, the preparation methods and synthetic conditions for preparing g-C 3 N 4 with different morphologies, such as conventional bulk g-C 3 N 4 , g-C 3 N 4 nanosheets, and g-C 3 N 4 quantum dots, are introduced in detail. By reviewing recent advances in g-C 3 N 4-based nanomaterials in ion sensors, biosensors, gas sensors and humidity sensors, this study provides more comprehensive and in-depth information for the further design of g-C 3 N 4based sensors with enhanced performance. A brief outlook of g-C 3 N 4-based sensors is presented as the conclusion of this review.

Graphitic carbon nitride (g-C3N4) is a two-dimensional conjugated polymer that has attracted the interest of researchers and industrial communities owing to its outstanding analytical merits such as low-cost synthesis, high stability, unique electronic properties, catalytic ability, high quantum yield, nontoxicity, metal-free, low bandgap energy, and electron-rich properties. Notably, graphitic carbon nitride (g-C3N4) is the most stable allotrope of carbon nitrides. It has been explored in various analytical fields due to its excellent biocompatibility properties, including ease of surface functionalization and hydrogen-bonding. Graphitic carbon nitride (g-C3N4) acts as a nanomediator and serves as an immobilization layer to detect various biomolecules. Numerous reports have been presented in the literature on applying graphitic carbon nitride (g-C3N4) for the construction of electrochemical sensors and biosensors. Different electrochemical techniques such as cyclic voltammetry, electrochemiluminescence, electrochemical impedance spectroscopy, square wave anodic stripping voltammetry, and amperometry techniques have been extensively used for the detection of biologic molecules and heavy metals, with high sensitivity and good selectivity. For this reason, the leading drive of this review is to stress the importance of employing graphitic carbon nitride (g-C3N4) for the fabrication of electrochemical sensors and biosensors.
