Chemical sensor devices are rapidly developing due to the demand for healthcare, environmental monitoring, manufacturing industry and smart home. Unlike traditional materials, metal–organic frameworks (MOFs) exhibit excellent prospects in chemical sensing devices due to the designability of metals and ligands, tunable pore size and abundant functional sites. By integrating MOFs with devices, the excellent sensing performance of MOFs and the portability of devices have been combined, making them stand out in areas such as gas detection and disease diagnosis. Here, we summarize the basic methods for combining MOFs with devices, the sensing mechanisms and chemical sensor devices based on MOFs in recent years, including electrochemical, electronic, electromechanical and optoelectronic sensor and devices. Finally, inspired by previous studies, the drawbacks and future prospects of chemical sensing devices based on MOFs are presented.

Addressing water pollution with toxic metals offers a significant global One health challenge, aggravated by uncontrolled contamination consequential of urbanization and industrialization on a massive scale. Nanoremediation is an impending and economical solution for wastewater remediation, predominantly for heavy metal ions, notwithstanding concerns concerning the ecotoxicity of nanotechnology. Nanomaterials demonstrate suitability for wastewater remediation owing to their tremendous adsorption efficacy, vast stoichiometry, tunable physicochemical properties, and rich surface chemistries. This comprehensive review summarizes the state-of-the-art strategically engineered nanomaterials and their advanced nanocomposites for remediating a range of heavy metals from wastewater. Diverse nanomaterials-based heavy metal remediation mechanisms, including adsorption, photocatalysis, nano-filtration, sensing and biosorption, and disinfection, are described. It explores the tailoring of different physicochemical attributes (surface chemistry, surface area, morphology, porosity, band gap, regeneration capability) of diversified nanomaterials including metals, polymers, metal oxides, carbon nanomaterials, activated charcoal, zeolites, and advanced 2D nanomaterials (graphene and its derivatives, borophene, boron nitride, phosphorene and MXenes) and environmental factors (temperature, contact time, pH, and adsorbent dosage) for selective heavy metal remediation from contaminated water. Furthermore, the review delves into the impact of nanoremediation on One Health by evaluating the ecological footprint, associated challenges, potential solutions, and prospects for combination with modern-age technologies for wastewater treatment, converging on advancing environmental sustainability.

Supercapacitors have garnered significant attention in recent years owing to their exceptional attributes, such as high power density, prolonged cycle stability, and the capacity to fulfil the gap between the traditional capacitor and lithium-ion battery. Nanostructures with different dimensions (zero-dimensional, 0D; one-dimensional, 1D; two-dimensional, 2D; and three-dimensional, 3D) were employed as electrodes. Such material’s architecture at the nanoscale has resulted in outstanding electrochemical characteristics, contributing to the development of high-performance Supercapacitors. Recent advances in the design of nanostructured electrode materials for Supercapacitors were highlighted and new insight into the structure property relationship is provided in this authoritative review. Unique classification of electrode materials based on dimensionality, namely, 0D, 1D, 2D and 3D was provided with emphasis on performance, namely, specific capacitance, energy density, power density and cyclability. The impact of nanostructures on key Supercapacitor properties that include the specific capacitance, charge transfer kinetics, diffusion, rate capability, as well as cycle life were also highlighted. These insights serve as a guidance for the development of commercially viable Supercapacitors with applications in day to day life, for instance, in drones used in the war-zones.

The excellent stability and economic benefits of nanozymes have piqued researchers’ interest as they represent a type of nanomaterials with enzyme-catalyzed capabilities. Among the various materials used as nanozymes, covalent organic frameworks (COFs) are favored by an extensive number of researchers as an emerging organic framework material because they can be rationally designed to mimic enzymes with desirable catalytic activities and have a high specific surface area and tunable pore structure. Therefore, in this paper, we provided a comprehensive overview of the advances of COFs-based nanozymes in which different construction strategies were involved, with special emphasis on heterogeneous synthesis methods, including pathways combining COFs with metal nanoparticles, enzymes, and metal organic frameworks, respectively. In addition, photocatalysis and electrocatalysis mechanism of COFs-based nanozymes in the field of energy conversion was discussed to conceive next-generation novelty applications of organic pollutants degradation, hydrogen production, antimicrobial, and anticancer therapy. Especially, the development of colorimetric and electrochemical sensors according to COFs-based nanozymes for sensing antioxidants, radioactive elements, antibiotics, and pesticide residues was also summarized. Finally, a brief discussion on the difficulties and potential applications of COFs-based nanozymes was held. We believe that this review can provide fresh perspective on the access of novelty COFs-based enzymes with user-defined high stability, and may bring about more intriguing applications.

The pursuit of efficient catalysts is a hot topic of great concerning in the Fenton process. Iron oxychloride (FeOCl) is a kind of ternary layered compound with van der Waals gap weakly linked by neighboring Cl atoms. The peculiar configuration of surface-exposed Fe atoms and the reducible electronic features endow FeOCl with remarkable catalytic reactivity for the activation of H2O2. Thereby, FeOCl is deemed as an exceptional heterogeneous Fenton-like catalyst. Due to the drawbacks of inevitably iron leaching, lack of active sites, and slow reduction rate of Fe (III) in the FeOCl-mediated Fenton-like reactions, numerous efforts have been made to achieve more satisfactory catalytic performance and extend its application scope. The article briefly introduces the structure and synthesis of FeOCl and elucidates the mechanisms for catalytic H2O2 activation. Subsequently, the strategies to strengthen the catalytic performance of FeOCl and related applications are summarized. At length, future research needs of FeOCl-based catalysts are provided, expecting to offer valuable information for the development of FeOCl in Fenton chemistry.

The pervasive contamination of industrial, domestic, and agricultural wastewater with nitrate poses profound ecological and public health risks. Traditional methods for remediating nitrate-laden water face formidable challenges due to its high solubility and stability. However, a promising solution emerges in the form of electrochemical nitrate reduction (eNO3RR), offering both efficient nitrate removal and valuable ammonia generation in a sustainable manner. This review explores the burgeoning field of eNO3RR, focusing on recent advancements utilizing porous crystalline framework materials − metal–organic frameworks (MOFs) and covalent-organic frameworks (COFs) − as a novel class of electrocatalysts. These innovative materials exhibit unique properties such as adjustable porosity, diverse structures, tunable pore sizes, and well-defined active sites, making them ideal candidates for enhancing the efficiency and selectivity of nitrate reduction under ambient conditions. By dissecting the structure–activity relationship inherent in MOF/COF-based electrocatalysts, this review aims to provide a comprehensive understanding of their role in driving the conversion of NO3− to NH3. Moreover, it identifies current challenges and proposes future prospects for leveraging these advanced materials in the sustainable conversion of nitrate pollutants, offering a glimpse into a greener and more effective approach to water remediation and resource recovery.

This article overviews the structures and properties of coordination polymers (CPs) with unsubstituted exo-macrocyclic ligands formed by coordinating inner macrocyclic ring donor atom(s) to the metal cation. The unique properties and applications of CPs are not solely dependent on their chemical composition, which includes metal ions, ligands, and anions. They are also influenced by dimensionality and motifs that can be creatively crafted to a certain extent. Due to the cyclic nature, designing macrocyclic ligands to bind specific metal cations, anions, or neutral species is possible if endo-cyclic coordination occurs. The exo-coordination of inner macrocyclic ring donor atoms to a metal ion(s) is a less common coordination mode that favors the formation of polymeric species. The primary focus of this article pertains to the correlation between designable macrocycle characteristics and the structural attributes of emerged CPs. A comprehensive review of crystal structures and structural motifs was done to set specific guidelines for designing macrocyclic ligands that tend to form exo-coordinated CPs. The coordination properties of ligands were analyzed concerning the donor atom set, cavity size, linkers between donor atoms, and anion influence to discuss and set applicable guidelines for designing macrocyclic CPs. The application of the investigated CPs as optical materials and biologically active substances was mentioned, and unfortunately, the broader application of these compounds is scarce. Therefore, future perspectives on these materials, such as gas sorption, conductivity, catalysis, and energetic materials, were conferred.

The exposure of certain metal ions poses significant risks to environmental and biological systems, prompting extensive research among chemists over the past few decades in the design and synthesis of chemosensors capable of sensing and quantifying these chemical species. Fluorescence techniques, known for their high sensitivity, have emerged as excellent tools for advancing chemosensor development. The appeal of peptide-based chemosensors lies in their remarkable biocompatibility, water solubility, low toxicity, and convenient conjugation to relevant biological macromolecules. These attributes position them as valuable tools for the sensing and estimation of biochemical species. In this review, different kinds of fluorescent peptide-based chemosensors that are selective for metal ions are examined, and their coordination modes, detecting methods, and synthesis pathways for fluorophore conjugation with peptide chains are explained, as well.
