“…have been developed to convert the LDHs into 2D sheets through delamination. − These 2D sheets, due to high surface area, rich active sites, and excellent visible absorption, can induce various photochemical reactions. The face-to-face interaction of LDHs with carbon nitride to make the vdW heterojunction has been found to boost photocatalytic performance. − The potential of such a combination has already been traversed by Song et al Within a short span, a few more reports have emerged on the 2D/2D heterojunction/close contact of carbon nitrides and LDHs. − …”

The surging demand for energy and staggering pollutants in the environment have geared the scientific community to explore sustainable pathways that are economically feasible and environmentally compelling. In this context, harnessing solar energy using semiconductor materials to generate charge pairs to drive photoredox reactions has been envisioned as a futuristic approach. Numerous inorganic crystals with promising nanoregime properties investigated in the past decade have yet to demonstrate practical application due to limited photon absorption and sluggish charge separation kinetics. Two-dimensional semiconductors with tunable optical and electronic properties and quasi-resistance-free lateral charge transfer mechanisms have shown great promise in photocatalysis. Polymeric graphitic carbon nitride (g-C3N4) is among the most promising candidates due to fine-tuned band edges and the feasibility of optimizing the optical properties via materials genomics. Constructing a two-dimensional (2D)/2D van der Waals (vdW) heterojunction by allies of 2D carbon nitride sheets and other 2D semiconductors has demonstrated enhanced charge separation with improved visible photon absorption, and the performance is not restricted by the lattice matching of constituting materials. With the advent of new 2D semiconductors over the recent past, the 2D/2D heterojunction assemblies are gaining momentum to design high performance photocatalysts for numerous applications. This review aims to highlight recent advancements and key understanding in carbon nitride based 2D/2D heterojunctions and their applications in photocatalysis, including small molecules activation, conversion, and degradations. We conclude with a forward-looking perspective discussing the key challenges and opportunity areas for future research.

“…Furthermore, another study found that the photocatalytic degradation of 2,4 dinitrophenol NiFe LDH and S-doped graphitic carbon nitride with NiFe LDH (SGCN/NiFe LDH) exhibited 55 % and 98 % degradation efficiencies, respectively. In this case, the S dopant increased the number of active sites, and SGCN/NiFe LDH decreased the electron-hole recombination of the NiFe LDH [25] .…”

“…g-CN has also been used as one component in heterojunctions and multicomponent photocatalyst for water treatment. 847 Among the various systems those combining g-CN and TiO2 as well as MOFs have been intensively investigated. The current state of the art can be summarized indicating that issues of sunlight efficiency and stability of modified TiO2 forms have not been yet satisfactorily solved and there is ample room for improvement.…”
