Using sunlight to drive chemical reactions via photocatalysis is paramount for a sustainable future.Among several photocatalysts,employing layered double hydrides(LDH) for photocatalytic application is most straightforward and desirable owing to their distinctive two-dimensional(2D) lamellar structure and optical attributes.This article reviews the advancements in bimetallic/trimetallic LDHs and various strategies to achieve high efficiency toward an outstanding performing photocatalyst.Firstly,the tuning of LDH components that control the electro nic and structural properties is explained.The tu ning obtained through the adoption,combination,and incorporation of different cations and anions is also explained.The progress of modification methods,such as the adoption of different morphologies,delamination,and defect engineering towards enhanced photocatalytic activities,is discussed in the mainstream.The band engineering,structural characteristics,and redox tuning are further deliberated to maximize solar energy harvesting for different photocatalytic applications.Finally,the progress obtained in forming hierarchical heterostructures through hybridization with other semiconductors or conducting materials is systematically disclosed to get maximum photocatalytic performance.Moreover,the structural changes during the in-situ synthesis of LDH and the stability of LDH-based photocatalysts are deliberated.The review also summarizes the improvements in LDH properties obtained through modification tactics and discusses the prospects for future energy and environmental applications.

With the increasing demand for energy, various emerging energy storage/conversion technologies have gradually penetrated human life, providing numerous conveniences. The practical application efficiency is often affected by the slow kinetics of hydrogen or oxygen electrocatalytic reactions(hydrogen evolution and oxidation reactions, oxygen evolution and reduction reactions) among the emerging devices. Therefore, the researchers devote to finding cost-effective electrocatalysts. Non-noble metal catalysts have low cost and good catalytic activity, but poor stability, agglomeration, dissolution, and other problems will occur after a long cycle, such as transition metal oxides and carbides. Transition metal nitrides(TMNs) stand out among all kinds of non-noble metal catalysts because of the intrinsic platinum-like electrocatalytic activities, relatively high conductivity, and wide range of tunability. In this review, the applications of TMNs in electrocatalytic fields are summarized based on the number of metals contained in TMNs. The practical application potentials of TMNs in fuel cell, water splitting, zinc-air battery and other electrochemical energy storage/conversion devices are also listed. Finally, the design strategies and viewpoints of TMNs-based electrocatalyst are summarized. The potential challenges of TMNs-based electrocatalyst in the development of electrocatalytic energy devices in the future are prospected.

With the continuous deepening of China’s internationalization process and the expansion of foreign exchanges, bilingual, even multilingual public signs have emerged in colleges and universities in response to the rising number of foreign students and teachers. While English public signs have become increasingly prominent, the English translation quality of public signs varies greatly. Guided by such translation strategies as literal translation, free translation and translation modification, this paper investigates and analyzes the current situation of English translation of public signs in colleges and universities based on field investigation and inductive analysis, so as to discover the existing problems in the English translation of public signs and carry out studies on its improvement methods to promote the standardization of English translation of public signs in colleges and universities.

Metal‐organic frameworks(MOFs)have attracted considerable attention as promising next‐generation active electrode materials for lithium‐ion batteries(LIBs)or sodium‐ion batteries(SIBs)because of ultrahigh specific surface area,uniformly distributed pores,and tunable structure.However,there are some disadvantages inevitably far from meeting commercial requirements,such as low conductivity,inconvenient electron transmission,and unsatisfactory circulation stability.In this review,a comprehensive summary of MOFs‐based electrode materials is presented and discussed.First,the general Li^(^(+))/Na^(+)storage mechanism in MOFs‐based electrode materials,including conversion‐and insertion‐type reactions,are summarized with details of active inorganic/organic ligands.Second,MOFs as anode materials for LIBs/SIBs are emphasized and improved on the electrochemical performances.Furthermore,very few research literature on MOFs‐based cathode materials is also discussed.Finally,opinions and prospects on the current challenge of MOFs‐based electrode materials are provided for future research directions.

Potassium-ion batteries(PIBs)have been considered as promising candidates in the post-lithium-ion battery era.Till now,a large number of materials have been used as electrode materials for PIBs,among which vanadium oxides exhibit great potentiality.Vanadium oxides can provide multiple electron transfers during electrochemical reactions because vanadium possesses a variety of oxidation states.Meanwhile,their relatively low cost and superior material,structural,and physicochemical properties endow them with strong competitiveness.Although some inspiring research results have been achieved,many issues and challenges remain to be further addressed.Herein,we systematically summarize the research progress of vanadium oxides for PIBs.Then,feasible improvement strategies for the material properties and electrochemical performance are introduced.Finally,the existing challenges and perspectives are discussed with a view to promoting the development of vanadium oxides and accelerating their practical applications.
