Waste polyethylene terephthalate (PET) plastics in the environment are accumulated worldwide, posing a great threat to ecological security and human health. Considering that waste PET plastics contain rich industrial raw materials like terephthalic acid (H₂BDC) and ethylene glycol (EG), it was essential to recycle waste PET plastics for the sustainable development of human society. Recent studies have indicated that waste PET plastics could be converted into high value-added metal-organic frameworks (MOFs) and their composites. In addition, producing MOFs using waste PET plastics via chemical recycling method displayed high potential in realizing closed-loop recycling of waste PET plastics. Up to now, PET-derived MOFs-based functional materials have been used in adsorption, separation, catalysis, advanced oxidation processes, supercapacitor and antibacterial. This review systematically summarized the recent advances in PET-derived MOFs-based functional materials, which will deepen the understanding of the preparation, characterization and applications of waste PET plastic-derived MOFs-based functional materials.

Interfaces and intermediate phases, which both promote energy storage in batteries and trigger many degradations, have been a double-edged sword in battery development. To boost battery performance, the interface associated with the separator, in particular the modulation of the heterogeneous components and the microenvironment of the interface, can be more effective. Very recently, the emerging poly (vinylidene fluoride) (PVDF) separator, due to the simple film formation process, chemical inertness, and high dielectric constant, etc., has a significant superiority in the modification of internal separator and interface with the electrodes. Researchers have made great progress in modifying the internal interface, cathode electrolyte interface (CEI), and anode electrolyte interface (AEI) of composite separators. Enhanced interfacial interaction strategies including the participation of components in interfacial reactions and the provision of interfacial ion transport channels, and construct high Young's modulus interface can simultaneously improve the thermal, mechanical, electrochemical stability, and ionic-electronic equilibrium. Then, this work discusses the research progress of the interface improvement strategies in detail, and further summarizes the characterization techniques of the interface problems, which will highlight the necessity of the research and development of the interfacial chemistry of the next generation PVDF separators, along with vital insights on the future development.

Nowadays, the increasing emergence of energy and environmental issues requires the development of solar-driven photocatalytic technique. The materials design lays the groundwork for photocatalysis reaction, and among various high-performance photocatalytic materials, there is increasing attention on integrating plasmonic materials and metal-organic frameworks (MOFs) because the ensemble inherits the advantages of both materials and complementary solution to overcome inadequacies, and the composites also bring about new hot-spots and properties on basis of synergistic interactions. Therefore, this review timely summarizes the latest progress of plasmonic/MOFs composites in photocatalysis. Different to the previous review articles, we discuss the all-round plasmonic-based composites, including noble metal and non-noble metal plasmonic materials, with emphasis on the development of surface plasmon resonance mechanism, the integration strategies of plasmonic materials with MOFs and MOFs-derivatives, and the multiple photocatalytic application in water splitting, CO₂ reduction reaction, organic molecules degradation, and organic reaction. Meanwhile, we make a summary and present the challenges and perspectives for future research in this field. We believe that the continuous progress in the advancement of plasmonic MOFs platforms holds great potential for future applications in photocatalysis, offering promising prospects.

Cerium (Ce)-based materials are favored in electrocatalytic energy storage and conversion as the most representative member of the rare earth (RE) group. Ce has variable valence and high oxygen storage/release capacity based on abundant oxygen vacancies (O_V), which largely enhances the redox properties of catalysts. It cannot be ignored that the unique 4f electronic structure of the Ce allows it to operate as an electronic modulator to provide additional rhythm for adjusting the functional properties of the catalyst. Recently, emerging novel Ce-based electrocatalytic materials together with continuous progress in advanced characterization techniques (e.g., in situ spectroscopy) and theoretical computational studies continue to enhance our intrinsic knowledge of the electronic and structural effects of Ce and expand the application boundaries. This review presents the inherent fundamental theoretical advantages of Ce in electrocatalysis and further provides a comprehensive summary and constructive discussion of the important research advances in Ce-based electrocatalytic materials in the last five years. Finally, perspectives on the future outlook toward Ce-based advanced electrocatalysts are advocated.

Recent developments in synthetic strategies have enabled the formation of increasingly complex hybrid functional materials incorporating both organic and inorganic components that synergistically contribute towards enhanced overall properties. Polyoxometalates (POMs), a large family of metal-oxo nanoclusters, are particularly suitable inorganic platforms for the formation of such functional materials due to their well-defined yet versatile structures, as well as their tunable physical and chemical properties. Furthermore, biomolecules – such as amino acids, peptides, proteins, porphyrins, nucleic acids, sugars, vitamins, etc. – and their synthetic derivatives have attracted increasing interest as the organic components. These biomolecules can be combined with POMs in multiple ways, either through covalent attachment to the POM and/or through supramolecular interactions, to form POM-biomolecule hybrids. Such hybrids have demonstrated promising functionalities in a wide range of applications, particularly in catalysis, medicine, biotechnology, photonics, and materials science. This review provides a detailed overview of the current state of the art on the synthesis and post-functionalization of bioorganic-inorganic hybrid functional materials based on POMs and biomolecules along with their potential applications.

Reduced hourglass-shaped polyoxometalate [Mⁿ(P₄Mo^V₆O₃₁)₂]^(24−n)− (abbr. {M[P₄Mo^V₆]₂}) clusters, represent an emerging subfield of polyoxometalates (POMs) that has garnered widespread interest across various multidisciplinary domains, including structural chemistry, coordination chemistry, catalytic chemistry, inorganic chemistry, and material chemistry. This interest stems from their totally reduction state, unique electron storage/release characteristics, photochemical behavior and structural tailorability. Despite over four decades of research on {M[P₄Mo^V₆]₂} clusters and the identification of more than 200 functional compounds based on this structure, this area remains relatively unexplored compared to other POM family members and there is a noticeable absence of focused reviews summarizing this field. This review offers a comprehensive survey on the synthetic strategies, structural characteristics and assembly mechanism of {M[P₄Mo^V₆]₂} POMs, as well as their applications in various functional areas such as catalysis, magnetism, fluorescence, proton conduction, energy conversion. Additionally, it also discusses the structure–activity relationships of these materials, highlights the current challenges, and provides an outlook for future research directions, aiming to inspire new investigations and advancements in this fascinating realm of POM chemistry.

Wound healing is a crucial but complex process that represents an onerous burden on both individuals and the healthcare system in the alarming growth of chronic diseases. Infection and inflammation as external factors may worsen the healing process, leading to severe tissue damage. Hence, embarking on state-of-the-art and green approaches to exalt wound healing is of utmost significance. Natural-origin polymers derived from renewable sources have a lower infection footprint for skin regeneration, good biological interpretation, enzyme-controlled degradability, and elevated chemical versatility. Herein, this review systematically details the in-depth information on utilizing biopolymers for wound dressing. We aim to emphasize the importance of functional groups of biopolymers in wound healing, which offer excellent antibacterial activity, and also highlight how desirable swelling ratio and tensile strength can enhance wound healing activity. While this review provides newcomers an invaluable insight into the development of biomaterials for futuristic applications, it also discusses the challenges posed by some factors like poor mechanical properties. We hope this study will purvey a panoramic sketch of biopolymer-based hydrogel to improve wound healing and concede that a more sustainable and greener future is on the way.

The class of functional materials centralized on luminescent metal–organic frameworks (LMOFs) has recently been at the forefront of optical sensing. LMOFs exhibit fascinating luminescence properties, functional diversities, and dynamic participation in supramolecular interactions, making these materials highly promising for ‘molecular recognition’ purposes. Interestingly, LMOFs can be deliberately downsized to nano-realm to construct nano-structured LMOFs or LMOF-nanosheets with enhanced surface properties, including interface-driven toxic analyte recognition. Besides, by adaptation of suitable synthesis routes, LMOF-composites (MOF@Lanthanides, MOF@polymers, Dye@MOFs, etc.) with enhanced stability, fluorescence properties, and new morphological features may be produced. This review article critically discusses the progression of LMOFs and allied materials toward effective monitoring of organic environmental contaminants (OECs) in the last few years (2018–2023). As OECs, we focus here on three categories: (a) explosive nitroaromatic compounds (NACs), (b) polycyclic aromatic hydrocarbons (PAHs), and (iii) endocrine-disrupting chemicals (EDCs). In the current situation, mutagenic NACs are employed profusely in terrorist activities and as a precursor to several industrially essential processes. Further, unrestricted industrialization has contributed noticeably to the emission of carcinogenic PAHs in air, soil, and water. Additionally, certain emerging chemicals, including pesticides, bisphenols, dioxins, antibiotics, polychlorinated biphenyls, etc., can cause severe harm to endocrine functions when they reach the human body. All these factors motivated us to present such a review article that is still scanty in its congeners but has an enormous impact on today’s scientific community. The article has been systematically divided into distinct sections. For example, popular design strategies (solvothermal, top-down and bottom-up approaches, exfoliation, interface-driven techniques, etc.) are discussed in Section 2. The features of linker-based luminescence, antenna effect, charge transfer, energy, and electron transfer pathways are presented in Section 3. The ligand design strategy, performance in bulk and nano-scale, detection sensitivity, and other relevant analytical results are also provided in detail. Moreover, we present a future perspective for the possible integration of artificial intelligence (AI) and machine learning (ML) approaches with LMOF-based next-generation materials for better quantification of toxic analytes.

Zinc-ion supercapacitors (ZSCs), emerging as advanced electrochemical energy storage devices, boast of high safety, power density and energy density, as well as eco-friendliness. However, there are three key factors currently impeding the development of ZSCs, including capacity decay of unstable cathodes, hydrogen evolution in the electrolyte, and dendrite formation on the zinc anode surface. To effectively tackle these challenges, the design of ZSCs should be approached comprehensively, considering various aspects. This work delves into the fundamental principles, advantages, and prospective applications of ZSCs. Detailed strategies for enhancing ZSC performance is summarized and the underlying mechanisms is elucidated, focusing on boosting cathode capacity, inhibiting dendrite growth on the anode, and regulating the ion–solvent structure in the electrolyte. Furthermore, this work analyzes future research directions for ZSCs, aiming to expand the voltage window, enhance energy density, extend cycle life, explore various application scenarios, and more effectively address the evolving requirements of future energy storage. The comprehensive optimization of the ZSC design shows great potential for unleashing their capabilities as a high-performance energy storage technology, playing a crucial role in the domain of sustainable energy.
