“…[301] The first principles calculations suggested that the introduction of heteroatoms such as B etc into arsenene can easily tune its electronic structure to accommodate the excellent catalytic activities toward HER and OER. [302] In summary, the electrocatalytic applications of Xenes have obtained insufficient concerns and required to be exploited. Furthermore, the relationship of structures and activities of Xenes can be deeply investigated for the rational design of pure Xenes with desired structures.…”

As an emerging subclass of 2D materials, Xenes (e.g., borophene, silicene, germanene, stanene, phosphorene, arsenene, antimonene, and bismuthene) consist of one single element and have opened the door for various important applications. Benefiting from their impressive characteristics, including ultrathin folded structure, ultrahigh surface–volume ratio, excellent mechanical strength and flexibility, Xenes are considered as promising electrode materials in the field of electrochemical energy with large capacity, high rate, and high safety. This review provides a comprehensive summary of selected properties, synthetic challenges, and the latest theoretical and experimental advances in the energy‐related applications of Xenes, including Li/Na ion batteries, Li–S batteries, electrocatalysis, and supercapacitors. Finally, the challenges and outlook of this emerging field are discussed.

“…The concentration of ZnSO 4 solution was 0.05 mol•l -1 , and the volume fraction of anhydrous ethanol was 25 %. Anhydrous ethanol was an additive, which weakens the hydrogen evolution reaction in the electrolyte solution [21,22], and maximizes the deposition of ZnO while ensuring a certain amount of OH -. The concentration of the electrolyte solution should be kept stable in order to reduce the experimental error, so the electrolyte solution was changed every 5 days.…”

For many years, researches have investigated concrete repair technologies including epoxy resin injection technology, bioremediation technology and self-healing technology. However, these repair methods have proven to be expensive and cumbersome to be carry out. A more recent technology electrochemical deposition, the focus of this paper emphases in a new way of healing concrete cracks that restores durability and mechanical strength of a concrete structure. Therefore, the emphasis of the research work reported here in is to prove the repair efficiency of the electrodeposition method by adding carbon fiber and graphene to the concrete. By analyzing the mass change of the concrete, total charge passed, crack width variation, ultrasonic waves, sediment composition and morphology, it was found that the cracks with width of 0.3-0.5 mm in samples healed within 20 days. The repair efficiency of samples mixed with carbon fiber and graphene were better than specimens without carbon fiber and graphene. Moreover, the mass increase rate of a concrete samples mixed with carbon fiber and graphene was 10.15 ‰, which is twice the mass of conventional concrete. The results of SEM and X-ray diffraction analysis showed that the samples mixed with carbon fiber and graphene produced more ZnO and that had a continuous compact structure.

“…Besides photocatalysis, the use of excess electricity generated from renewables to split water into oxygen and hydrogen is of great value as hydrogen molecule is considered as one of the cleanest energy suppliers. Very recently, DFT calculations have been carried out to investigate the electrocatalytic activity of pristine and functionalized arsenene for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) . The dopants, including B, N, O, Ge, Ga, and Se atoms, were demonstrated to enhance the catalytic activity by substituting one of the As atoms in arsenene.…”

Research efforts in the area of two‐dimensional (2D) arsenene‐based materials have been fueled up recently due to similarities in honeycomb atomic structures and differences in physical and chemical properties between arsenene and graphene. The pioneering prediction of monolayered arsenene in 2015 and successful synthesis of multilayered arsenene nanoribbons in 2016 have promoted intensive subsequent studies, especially in the theoretical aspect. Density functional theory computations not only revealed desirable fundamental band gap, structural stability, and high carrier mobility of various arsenene‐based materials but also suggested promising applications in future optoelectronic and thermoelectric devices, as well as in the quantum spin Hall devices via surface functionalization and modulation of interlayer interactions. With an aim to present a comprehensive review on the tunable electronic structures of 2D arsenene‐based materials, our focus is placed on the tailoring routes through surface functionalization to modify the electronic and optoelectronic properties of the arsenenes. An emphasis is also given to recent progress in designing topological states in arsenene monolayers. The challenges and outlooks are also laid out in aspects of experimental fabrication, device performance, and arsenene‐based chemical reactions.
