“…Another negative aspect is the difficulty to deposit the catalyst on a conductive substrate for PEC devices, which still involves many steps and poor performance. [172] For developing 2D materials, it can help to search for catalysts by inverse design [165] in other areas, such as more efficient 2D membranes, [166] porous catalytic materials, [16,[167][168][169] metal-organic frameworks, [170] and batteries. [171] The 2D-nanocatalyst synthesis could be improved by using computational chemistry.…”

Due to their catalytic characteristics, including highly accessible active sites, excellent charge separation properties, great capability for adsorption of CO2 and H2O due to abundant surface defects, and adjustable electronic features, non‐oxide two‐dimensional nanomaterials have received great attention in areas like water splitting and carbon dioxide (CO2) reduction. There are diverse non‐oxide 2D semiconductors reported in literature, among them this review inspects closely the two‐dimensional transition‐metal dichalcogenides (TMDC), MXene materials, graphitic carbon nitride catalysts, metal‐organic frameworks (MOFs), and the heterojunctions of those. This investigation is expected to stimulate new research to improve the design and possible applications of 2D materials by strategies that involve controlling the structural, optical, and electronic properties impacting the catalysts’ activity, selectivity, and stability for successful application in the CO2 reduction or other catalytic reactions.

“…Type I and II heterostructures that have electronic structures with straddling (Type I) and staggered gap (Type II), have been widely investigated in photocatalysis 128,129 . Building up Type I/II heterostructure is an effective approach to promote the OWS performance of GCN by introducing a new electronic structure due to the Fermi level differences and enhancing the built‐in electric field in the space charge region to increase the charge separation 130 .…”

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.

“…With the development of industry and ever-increasing consumption of global fossil energy, clean and renewable energy resources such as wind, solar, and tidal energy have received widespread attention. 1,2 However, the development of indirect and discontinuous clean energy is restricted due to natural conditions and geographical distribution, while the inexpensive and efficient energy storage systems should be developed to fully use the renewable energy. 3,4 The rechargeable lithium-ion batteries have the advantages of high energy density, long cycle life, and lightweight characteristics, which endow them with wide commercial applications in portable electronic devices, electric vehicles, and so forth.…”

Biomass-derived carbon (BDC) is viewed as one of the most promising anode candidates for sodium-ion batteries (SIBs) owing to its natural abundance, low cost, and sustainability. However, fabrication of BDC with a preferred microstructure and morphology for high-performance sodium storage still remains a dilemma. Herein, we report using natural parasol fluff as a biomass precursor to highlight the significant role of the tubular structure for achieving high electrochemical performances with BDC. Different from high-temperature pyrolysis (over 1000 °C) commonly used for BDC, the interconnected porous carbon framework with a well-maintained tubular structure was prepared in a mild calcination temperature of 500 °C with the aid of KOH activation and Co 2+ -assisted graphitization. The as-prepared material with a large interlayer spacing (0.405 nm) and abundant self-doping heteroatoms demonstrates its excellent performance as the anode of SIBs by delivering a reversible capacity of 359.0 mA h g −1 at 30 mA g −1 . Impressively, its full-cell capacity reaches 257.2 mA h g −1 at 30 mA g −1 , which is among the highest values for carbon-based full-cell assembly. In addition to offering a potential industrializable BDC choice, this work highlights the significance of the tubular structure and provides tactics for screening of biomass precursors as well as the design of high-performance carbonaceous materials.
