The design of the structure and catalytic function of electrocatalysts is an important core technology to solve the energy crisis. To realize the construction of ideal electrocatalysts, it is necessary to understand the structure-activity relationship between the internal structure (physical structure, electronic structure, electrochemical structure, etc.) of the active sites in electrocatalysts and the heterogeneous electrocatalytic performance from a comprehensive perspective. Obviously, the internal structure of electrocatalysts mainly depends on the actual coordination environment of their active sites. Generally, the coordination environment of the active site covers many aspects, such as coordination number (C.N.), bonding type, steric hindrance, bond length and bond angle, density of active center, etc. By establishing a structure-activity relationship between the coordination environment and the heterogeneous electrocatalytic performance, the design of the ideal coordination environment model of the active site is guided. Moreover, according to the type of catalyst and the location of the active site, the appropriate coordination environment control strategies were proposed for the active site at the bulk catalyst, the heterointerface, the carrier, as well as the electrocatalytic reaction interface, respectively. In particular, the local coordination environment of electrocatalytic reaction interface, as an important factor that directly affects the electrocatalytic performance, is often neglected. Then, the visualization of the coordination environment of the active site is realized by electron microscopy, spectroscopy configuration and In-situ monitoring techniques. Finally, this work summarizes the optimization of the coordination environment for the heterogeneous electrocatalytic reaction, and puts forward personal perspectives on the current challenges. We believe that this work will achieve the directional construction of high-efficiency electrocatalysts guided by the coordination environment of active sites, pointing out the direction for developing new energy in the future.

电催化剂的结构和催化功能设计是解决能源危机的重要核心技术。要实现理想电催化剂的构建，就必须从全面的角度认识电催化剂活性位点内部结构（物理结构、电子结构、电化学结构等）与异相电催化性能之间的构效关系。显然，电催化剂的内部结构主要取决于其活性位点的实际配位环境。一般来说，活性位点的配位环境包括配位数（C.N.）、成键类型、立体阻碍、键长和键角、活性中心密度等多个方面。通过建立配位环境与异相电催化性能之间的结构-活性关系，可以指导设计理想的活性位点配位环境模型。此外，根据催化剂的类型和活性位点的位置，分别提出了活性位点在块体催化剂、异质界面、载体以及电催化反应界面的相应配位环境控制策略。其中，电催化反应界面的局部配位环境作为直接影响电催化性能的重要因素，往往被忽视。因此，本研究首先介绍了电催化反应界面的配位环境，然后通过电子显微镜、光谱配置和原位监测技术实现了活性位点配位环境的可视化。最后，这项工作总结了异相电催化反应配位环境的优化，并对当前面临的挑战提出了个人观点。我们相信，这项工作将实现以活性位点配位环境为导向的高效电催化剂的定向构建，为未来开发新能源指明方向。

Over the past few decades, selective halide recognition has garnered widespread attention due to its crucial roles in the environmental and biological processes. However, synthetic receptors capable of binding halides in aqueous media remains a key challenge in modern supramolecular chemistry. Consequently, there have been hitherto a number of reviews published, which mainly focus on specific halides recognition based on colorimetric and/or fluorometric methods. This review article provides a comprehensive overview and highlights the effective strategies, particularly on receptors designing principles, mechanism, extraction, and real time applications for the halides recognition. It is expected that this review could facilitate advancements in the design and synthesis of receptors for recognizing and extracting halides in water.

在过去的几十年中，选择性卤化物识别因其在环境和生物中的重要作用而受到广泛关注。

In this paper, we review the different confinement strategies of heterogeneous Fenton-like catalysts based on their important roles in catalyst design. Confinement effects can effectively promote the mass transfer ability and interference resistance of heterogeneous Fenton-like reaction processes, and modify the electronic state of the active site to enhance the Fenton-like reaction activity. In this paper, from the different confinement dimensions of the active center (including 3D, 2D, 1D and 0D), we review the effects of confinement strategies on the Fenton-like catalytic reaction in different dimensions. The influence of the morphology and type of confinement substrates on space-confined heterogeneous Fenton-like catalysts, as well as strategies for coordination modification of single-atom active sites on heterogeneous Fenton-like catalysts are described. Finally, we summarize and look forward to the challenges that still exist in the design of confinement strategies and future developing directions for heterogeneous Fenton-like catalysts.

Metal-organic frameworks (MOF) are promising electrocatalysts for the oxygen evolution reaction (OER). MOFs precatalysts undergo a structural reconstruction that results in the formation of transition metal hydroxyoxides (MOOH) during the OER process, which are widely regarded as the authentic catalytic species for OER. This review comprehensively summarizes the recent progress in the research field of MOF-based OER electrocatalysts in terms of structural reconstruction and analyzes in depth the intrinsic relationship between dynamic reconstruction mechanisms and structural activity. By studying two primary triggering factors for reconstruction: the manipulation of the electrochemical environment and the MOF structure, we aim to understand in detail the dynamic pathway of MOF reconstruction and its correlation with the OER catalytic activity in real time. In addition, this review also addresses the self-healing capabilities of reconstructed MOFs and the stability of their framework structures, providing important insights into the long-term performance of these catalysts. Finally, we propose a new direction for future research based on the current state of knowledge, aimed to better understanding how the microchemical environment affects catalytic activity during dynamic reconstruction, in order to facilitate the design and development of highly efficient MOF-based OER catalysts in the future and make it easier to navigate the future.

As emerging platforms, nanoporous-based biosensors have potentially useful applications for sensitive and selective detection of various analytes. The integration of nanoporous materials (e.g., nanocarbons, mesoporous, metal–organic frameworks (MOFs), and MOF-based nanocomposites, etc.) with various transduction techniques, such as electrochemical, optical, and mass-sensitized, has led to the development of biosensors for a wide spectrum of applications in healthcare, environmental monitoring, and food safety. These biosensors take advantage of the unique properties of nanoporous materials, such as tunable pore size and selective surface chemistry with high surface area, and enhance the interaction between the analyte and the recognition element. Overall, biosensors based on nanoporous material have very low limits of detection and appropriate linear range.

Industrialization has significantly compromised air quality, environmental health, and human well-being. Therefore, it is highly necessary to develop efficient and cost-effective strategies to resolve the issue of environmental pollution while promoting sustainable energy production. Catalysts play a crucial role in the synthesis and conversion of valuable chemicals by providing more active sites that accelerate catalytic reactions, leading to proper activity and selectivity. However, challenges such as catalyst stability, cost-effectiveness, high surface area, reusability, and low loading amount need to be addressed. In this regard, metal organic frameworks (MOFs) could be an intelligent choice due to their tunable structure through altering metal centers and organic ligands along with their structural flexibility, high specific surface area, and diversity. These porous materials have found extensive application in heterogeneous catalysis and environmental remediation thanks to their low cost, abundance in nature and feasible preparation routes. Among first-row transition metal-based MOFs like vanadium (V)- and manganese (Mn)-containing structures have gained popularity in environmental remediation and catalysis due to their different redox states, stability, cost-effectiveness. As limited number of review articles have addressed V and Mn-containing MOFs compared to other first-row transition metals like Ni, Co, Cu and Fe, this review aims at exploring recent advancements in the V- and Mn-based MOFs, their composites, and derivatives within heterogeneous catalysis, highlighting applications in oxidative fuel desulfurization, CO₂ reduction, epoxidation, hydroxylation, oxidation of organic compounds, and environmental remediation, including the adsorption and elimination of organic dyes and CO₂ capture and conversion. Also, the review emphasizes the structure-performance relationship, offering new insights for overcoming existing challenges and advancing the field.

工业化严重损害了空气质量、环境健康和人类福祉。因此，在促进可持续能源生产的同时，极有必要制定高效且具有成本效益的战略来解决环境污染问题。催化剂通过提供更多的活性位点来加速催化反应，从而获得适当的活性和选择性，在有价值化学品的合成和转化过程中发挥着至关重要的作用。然而，催化剂的稳定性、成本效益、高表面积、可重复使用性和低负载量等挑战亟待解决。在这方面，金属有机框架（MOFs）可能是一个明智的选择，因为它们可以通过改变金属中心和有机配体来调整结构，同时还具有结构灵活、比表面积高和多样性等特点。这些多孔材料成本低廉，在自然界中含量丰富，制备方法可行，因此在异相催化和环境修复领域得到了广泛应用。在第一排过渡金属基 MOFs 中，含钒（V）和锰（Mn）结构的 MOFs 因其不同的氧化还原状态、稳定性和成本效益而在环境修复和催化领域广受欢迎。与镍、钴、铜和铁等其他第一排过渡金属相比，研究含钒和锰 MOFs 的综述文章数量有限，因此本综述旨在探讨钒基和锰基 MOFs 及其复合材料和衍生物在异相催化领域的最新进展，重点介绍其在氧化燃料脱硫、二氧化碳还原、环氧化、羟基化、有机化合物氧化和环境修复（包括吸附和消除有机染料以及二氧化碳捕获和转化）中的应用。此外，该综述还强调了结构与性能之间的关系，为克服现有挑战和推动该领域的发展提供了新的见解。

Therefore, it is highly necessary to develop efficient and cost-effective strategies to resolve the issue of environmental pollution while promoting sustainable energy production. Catalysts play a crucial role in the synthesis and conversion of valuable chemicals by providing more active sites that accelerate catalytic reactions, leading to proper activity and selectivity. However, challenges such as catalyst stability, cost-effectiveness, high surface area, reusability, and low loading amount need to be addressed. In this regard, metal organic frameworks (MOFs) could be an intelligent choice due to their tunable structure through altering metal centers and organic ligands along with their structural flexibility, high specific surface area, and diversity.
