“…The g‐C 3 N 4 materials can also be used as the electrode materials for electrochemical sensing. Zhang et al modified a GC electrode with g‐C 3 N 4 nanosheets for the electrochemical detection of Hg 2+ . It was reported proposed that there is a strong affinity between the g‐C 3 N 4 nanosheets and Hg 2+ through its –NH and –NH 2 groups.…”

Graphitic carbon nitrides (g-C N ) are a class of 2D polymeric materials mainly composed of carbon and nitrogen atoms. g-C N are attracting dramatically increasing interest in the areas of sensing, imaging, and therapy, due to their unique optical and electronic properties. Here, the luminescent properties (mainly includes photoluminescence and electrochemiluminescence), and catalytic and photoelectronic properties related to sensing and therapy applications of g-C N materials are reviewed. Furthermore, the fabrication and advantages of sensing, imaging and therapy systems based on g-C N materials are summarized. Finally, the future perspectives for developing the sensing, imaging and therapy applications of the g-C N materials are discussed.

“…Therefore, it is of great importance to research and develop sensitive sensing strategies for the recognition and detection of Hg 2+ in biological and environmental systems. Traditionally reported approaches available to monitor Hg 2+ in aqueous samples include atomic absorption spectrometry [5,6], atomic fluorescence spectrometry [7-9], inductively coupled plasma-mass spectrometry [10,11], fluorometry [12][13][14][15][16] and electrochemical analysis [17][18][19][20][21][22]. Recently, liquid crystal based sensor system and resonance Rayleigh scattering aptasensor are also be used to detect Hg 2+ [23,24].…”

“…Zhang et al reported a sensitive electrochemical sensor for trace mercury (Hg 2+ ) detection using g-C 3 N 4 nanosheets (~8-nm thick) ( Figure 4a) as an enhanced sensing platform. [75] The prepared g- poly(BPE)/g-C 3 N 4 composites were used in the simultaneous detection of Cd 2+ and Pb 2+ . [76] The conduction path on the surface of the working electrode was improved by the combination of poly(BPE) and g-C 3 N 4 , which provided a strong conjugating effect, promoting the adsorption of metal ions.…”

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.
