“…The energy density depends on the capacitance and the potential window by relation E ½CV 2 . Therefore, considerable efforts have been made to maximize "E" by enhancing "V" and "C." Among various types of electrochemical capacitors, 2D materials-based supercapacitors like graphene and MoS 2 , are gaining significant interest because of their intrinsic features, such as their high conductivity, low cost, flexibility, wide potential, window and fast redox reaction (Firmiano et al, 2014;Hao et al, 2014;Sun et al, 2015;Lv et al, 2016;Mehran and Baig, 2019;Muthu and Gopalan, 2019;Khan et al, 2020;Rani et al, 2020;Rathinamala et al, 2020;Zhao et al, 2021).…”

“…It is also demonstrated that 2D materials can be combined with effective photocatalysts to improve efficiency (Yang, 2017 ). The structures and properties of various nanocomposites are also studied comprehensively by density functional theory, and the theoretical results are verified by experiments (Zhao et al, 2021 ). Figure 2g shows that the change of reaction temperature and time used to prepare the material will affect the morphology of the material, different reaction conditions also have a certain degree of influence on the catalytic performance (Chen et al, 2017 ).…”

The successful preparation and application of graphene shows that it is feasible for the materials with a thickness of a single atom or few atomic layers to exist stably in nature. These materials can exhibit unusual physical and chemical properties due to their special dimension effects. At present, researchers have made great achievements in the preparation, characterization, modification, and theoretical research of 2D materials. Because the structure of 2D materials is often similar, it has a certain degree of qualitative versatility. Besides, 2D materials often carry good catalytic performance on account of their more active sites and adjustable harmonic electronic structure. In this review, taking 2D materials as examples [graphene, boron nitride (h-BN), transition metal sulfide and so on], we review the crystal structure and preparation methods of these materials in recent years, focus on their photocatalyst properties (carbon dioxide reduction and hydrogen production), and discuss their applications and development prospects in the future.

Photocatalytic overall water splitting (OWS) without using any sacrificial reagent to realize H2 and O2 production in the stoichiometric ratio of 2:1 is viewed as the “holy grail” in the field of solar fuel production. Developing stable, low cost, and nontoxic photocatalysts that have satisfactory solar‐to‐hydrogen conversion efficiency is of significance but challenging for realizing the large‐scale use of this sustainable technology. Among various photocatalysts, graphitic carbon nitride (GCN) has shown great potential as an ideal candidate to fulfill the breakthrough in this dynamic research field due to its attractive physicochemical properties. Herein, for the first time, the state‐of‐the‐art research progress of GCN for photocatalytic OWS is reviewed. We first summarize the basic principle of photocatalytic OWS along with the advantages/challenges of GCN introduced. The strategies that have been used to modulate the OWS activity of GCN are then reviewed, including cocatalyst investigation, morphology modulation, atomic structure modification, crystallinity engineering, and heterostructure construction. Toward the end of the review, the concluding remarks and perspectives for the future development are presented, with our expectation to provide some new ideas for the design of advanced OWS photocatalysts.
