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.

“…To further enhance the electronic properties and sensing performance of binary nanocomposite, the surface decoration with graphitic carbon nitride (g‐C 3 N 4 ) was done. Graphitic carbon nitride (g‐C 3 N 4 ) is highly stable form of carbon nitrides with remarkable properties and peculiar structure [32, 33]. The uniqueness in structure and properties has received considerable attention in plethora of applications like photocatalysis, water splitting, fuel cells and in electrochemical sensors [34, 35].…”

Development of nanocomposite based electrochemical sensors for detection of toxic chemicals describes an environmentally benign strategy for monitoring the health of ecosystem. Herein, we reported in situ preparation of graphitic carbon nitride (g‐C3N4) decorated Ag2S/NiFe2O4 nanocomposite sensor by facile precipitation method. The electrochemical studies demonstrated efficient electrocatalytic activity of ternary nanocomposite pasted glassy carbon electrode (g‐C3N4@Ag2S/NiFe2O4/GCE) for selective detection of formaldehyde. Moreover, fabricated sensor exhibit rapid amperometric response with excellent selectivity, remarkable sensitivity (1681 μA mmol L−1 cm−2) and lower detection limit (LOD: 1.63 μmol L−1). It is noteworthy to mention that sensor exhibits good operational and long‐term storage stability.

“…7 It is worth noting that other solid state gas sensor technology has been tried for the detection of illegal drugs such as ephedrine, tramadol, nalbuphine, agomelatine, methamphetamine, cocaine, and also for the detection of doping. [8][9][10][11][12][13] Detection dogs are trained to target substances that have a detectable odour, which may be a substance other than the drug itself, such as a drug by-product. 14,15 Indeed, drugs oen have very low vapour pressures, which somewhat limits the chances of successful direct detection.…”
