“…The reason why pCN-N/ZIS-Z has excellent photocatalytic degradation and hydrogen production performance is mainly due to the following: (1) nanosheets with porous structures expand the surface area of the catalyst and provide more active sites for photocatalytic reactions. (2) The construction of the Z-scheme heterojunction improved the separation efficiency of photogenerated charges. (3) Introduction of defect engineering and oxygen-doping tend to trap electrons on the surface of pCN-N/ZIS-Z to reduce interior charge recombination, thereby generating more active participators for photocatalytic reactions.…”

“…At present, many studies have reported that hydrogen is precipitated by electrolysis of water, but this method is energy-intensive and costly and is not conducive to mass production. Therefore, exploring low-cost, simple and environmentally friendly methods to produce hydrogen has become an important research topic [1,2]. At the same time, with the progress of human society and the development of the industrial age, the use of antibiotics has increased due to the emergence of a variety of new diseases, and the entry of antibiotics into water will pose risks to human health and ecosystems [3][4][5][6][7].…”

Graphitic carbon nitride (g-C3N4) with a porous nano-structure, nitrogen vacancies, and oxygen-doping was prepared by the calcination method. Then, it was combined with ZnIn2S4 nanosheets containing zinc vacancies to construct a three-dimensional (3D) flower-like Z-scheme heterojunction (pCN-N/ZIS-Z), which was used for photocatalytic hydrogen evolution and the degradation of mixed pollutants. The constructed Z-scheme heterojunction improved the efficiency of photogenerated charges separation and migration, and the large surface area and porous characteristics provided more active sites. Doping and defect engineering can change the bandgap structure to improve the utilization of visible light, and can also capture photogenerated electrons to inhibit recombination, so as to promote the use of photogenerated electron-hole pairs in the photocatalytic redox process. Heterojunction and defect engineering synergized to form a continuous and efficient conductive operation framework, which achieves the hydrogen production of pCN-N/ZIS-Z (9189.8 µmol·h−1·g−1) at 58.9 times that of g-C3N4 (155.9 µmol·h−1·g−1), and the degradation rates of methyl orange and metronidazole in the mixed solution were 98.7% and 92.5%, respectively. Our research provides potential ideas for constructing a green and environmentally friendly Z-scheme heterojunction catalyst based on defect engineering to address the energy crisis and environmental restoration.

“…In addition, HEIs are also expected to take the place of existing functional materials due to their novel performance characteristics. It is clear that HEIs can be used as low-temperature superconducting materials, hydrogen evolution reaction (HER) catalysts, magnetic materials, and hydrogen storage materials to replace NbTi, single Pt, ferrite, and other commonly used functional materials [164][165][166][167].…”

High-performance structural materials are critical to the development of transportation, energy, and aerospace. In recent years, newly developed high-entropy alloys with a single-phase solid-solution structure have attracted wide attention from researchers due to their excellent properties. However, this new material also has inevitable shortcomings, such as brittleness at ambient temperature and thermodynamic instability at high temperature. Efforts have been made to introduce a small number of intermetallic compounds into single-phase solid-solution high-entropy alloys as a secondary phase to their enhance properties. Various studies have suggested that the performance of high-entropy alloys can be improved by introducing more intermetallic compounds. At that point, researchers designed an intermetallic compound-strengthened high-entropy alloy, which introduced a massive intermetallic compound as a coherent strengthening phase to further strengthen the matrix of the high-entropy alloy. Inspired from this, Fantao obtained a new alloy—high-entropy intermetallics—by introducing different alloying elements to multi-principalize the material in a previous study. This new alloy treats the intermetallic compound as the main phase and has advantages of both structural and functional materials. It is expected to become a new generation of high-performance amphibious high-entropy materials across the field of structure and function. In this review, we first demonstrate the inevitability of intermetallic compounds in high-entropy alloys and explain the importance of intermetallic compounds in improving the properties of high-entropy alloys. Secondly, we introduce two new high-entropy alloys mainly from the aspects of composition design, structure, underlying mechanism, and performance. Lastly, the high-entropy materials containing intermetallic compound phases are summarized, which lays a theoretical foundation for the development of new advanced materials.

Proton exchange membrane (PEM) water electrolysis represents one of the most promising technologies to achieve green hydrogen production, but currently its practical viability is largely affected by the slow reaction kinetics of the anodic oxygen evolution reaction (OER) in an acidic environment. While noble metalbased catalysts containing iridium or ruthenium are excellent catalysts for the acidic OER, their practical use in PEM electrolyzers is hindered due to their low abundance and high cost. Most recently, metal-organic frameworks (MOFs) have been demonstrated as a perfect platform to facilitate the design of acidic OER catalysts with both high efficiency and cost-effectiveness. Here, we provide a timely and comprehensive overview of the recent progress on MOFbased acidic OER catalysts. The fundamental mechanisms of the acidic OER are first introduced, followed by a summary of the development of pristine MOFs and MOF derivatives as acidic OER catalysts. Importantly, a number of catalyst design strategies are discussed aiming at improving the acidic OER catalytic performance of MOF-based candidates. The integration of MOF-based catalysts into real PEM water electrolyzers is also included. Finally, future research directions are provided to achieve better MOF-based catalysts operational in acidic environments and PEM devices.
