“…DPCN and NiFe‐LDH were prepared separately through calcination of urea in an atmosphere of Ar and H 2 at 550 and 540 °C, and by hydrothermal treatment with a Ni‐ and Fe‐based nitrate solution at 150 °C for 20 h. The DPCN/NRGO/NiFe‐LDH aerogel was then synthesized by using the hydrothermal method in a Teflon‐lined autoclave at 180 °C for 6 h. g‐C 3 N 4 and NiFe‐LDH were encapsulated and anchored within a 3D interconnected N‐doped graphene skeleton (Figure a). Zhan and co‐workers prepared a 3D graphene‐Co 2 Al LDH‐g‐C 3 N 4 (GR‐LDH‐g‐C 3 N 4 ) nanocomposite through hydrothermal treatment (160 °C for 6 h for GO‐LDH hydrogel) following a calcination–recovery (calcined GR‐LDH containing melamine powder at 600 °C for 3 h) procedure (Figure b) . The doping of g‐C 3 N 4 into the GR‐LDH network can increase catalytically active sites and stability, as well as achieve enzyme capture.…”

Solar‐driven photocatalysis with graphitic carbon nitride (g‐C3N4) is considered to be the most promising approach for the generation of H2 from water, the degradation of organic pollutants, and the reduction of CO2. However, bulk g‐C3N4 exhibits several drawbacks, such as a low specific surface area, high defect density, and fast charge recombination, which result in low photocatalytic performance. The construction of 3D porous hydrogels for g‐C3N4 through nanostructural engineering is a rapid, feasible, and cost‐effective technique to improve the adsorption capability, stability, and separability of the hydrogel composite; to increase the number of active sites; and to create an internal conductive path for facile charge transfer and high photocatalytic activity. This minireview summarizes recent progress in photocatalytic water splitting and dye degradation by using g‐C3N4‐based hydrogels, with respect to state‐of‐the‐art methods for synthesis, preparation, modification, and multicomponent coupling. Furthermore, comprehensive outlooks, future challenges, and concluding remarks regarding the use of g‐C3N4‐based hydrogels as highly efficient photocatalysts are presented.

“…Superior sensitivity and specificity of electrochemical sensors can only be achieved when there are well-covered recognition molecules or labels as bridges for electron transfer between electrodes and target molecules. Up to date, redox proteins such as hemoglobin (Hb) ( Figure 1a) 39,43,44,45,46,50,52,53,54,61,62,63,64,73,74 and myoglobin (Mb) 40,47,48,51,55,56,57,58,59,60,65,66,67 Enzymes are recognized as highly-selective biological catalysts that can dramatically reduce a specific biochemical process by lowering the threshold of activation energy. For example, horseradish peroxidase (HRP, MW 40000 Da) derived from the roots of horseradish 83 , has been applied in the fabrication of electrochemical biosensors by detecting reduction current of TCA in solution 41,68 .…”

Irreversible organ damage or even death frequently occurs when humans or animals unconsciously drink contaminated water. Therefore, in many countries drinking water is disinfected to ensure harmful pathogens are removed from drinking water. If upstream water treatment prior to disinfection is not adequate, disinfection by-products (DBPs) can be formed. DBPs can exist as wide variety of compounds, but up till now, only several typical compounds have drinking water standards attributed to them. However, it is apparent that the range of DBPs present in water can comprise of hundreds of compounds, some of which are at high enough concentrations that can be toxic or potentially carcinogenic. Hence, it becomes increasingly significant and urgent to develop an accessible, affordable and durable sensing platform for a broader range and more sensitive detection of DBPs. Compared with well-established laboratory detection techniques, electrochemical sensing has been identified as a promising alternative that will provide rapid, affordable and sensitive DBPs monitoring in remote water sources. Therefore, this article provides a review on current state-of-the-art development (within last decade) in electrochemical sensing to detect organic DBPs in water, which covered three major aspects: (1) recognition mechanism, (2) electrodes with signal amplification, and (3) signal read-out techniques. Moreover, comprehensive quality assessments on electrochemical biosensors, including linear detection range, limit of detection (LoD) and recovery, have also been summarized.

“…Zhan et al prepared a g-C 3 N 4 NP-decorated graphene assembly and Co 2 Al layered double hydroxide nanosheets (GR-LDH-C 3 N 4 ) by a simple hydrothermal method and subsequent calcination-recovery process. [183] Then, the conductive composite and chitosan (CTS) were used to immobilize hemoglobin (Hb) on a carbon ionic liquid electrode (CILE) to generate a biosensor for the detection of trichloroacetic acid (TCA). This bioelectrode exhibits a wide linear detection range from 0.2 to 36.0 mM with a low LOD (0.05 mM).…”

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.
