Zinc metal is an ideal anode for aqueous zinc-ion batteries (AZIBs) due to its high theoretical capacity and inherent safety. However, its practical application is hindered by dendrite growth and side reactions at the zinc anode/electrolyte interface, which severely degrade the cycling stability of AZIBs. Herein, an interfacial layer based on a quaternary ammonium functionalized polymer layer with iodide ions is proposed and applied to zinc anode surface to simultaneously mitigate dendrite growth and side reactions by optimizing Zn2+ transport and deposition behavior. The iodide ions serve as zincophilic sites that enhance the interfacial affinity toward Zn2+ and facilitate Zn2+ desolvation. The quaternary ammonium groups contribute to electrostatic regulation of interfacial ion distribution, thereby reducing anion participation near the Zn surface. This dual functional mechanism works synergistically homogenize Zn2+ flux and effectively mitigate dendrite growth. In addition, the uniform Zn2+ flux combined with improved surface hydrophilicity promotes the formation of a compatible and electrochemically stable interface on the zinc anode surface. Consequently, the QP@Zn||QP@Zn symmetric battery achieves a stable cycling lifespan over 2000 h at 5 mA cm–2/1 mAh cm–2, and maintains excellent rate performance at 15 mA cm–2. The QP@Zn||NVO full battery retains a specific capacity of 215 mAh g–1 after 1500 cycles at 5 A g–1. By integrating zincophilic iodide ions, quaternary ammonium groups, and a hydrophilic framework into the molecular design of the protective layer, this study not only provides feasible strategies for constructing high performance AZIBs, but also offers profound insights for regulating the zinc anode/electrolyte interface.

Zn-BDC-dmtrz with confined nonpolar pores preferentially adsorbs C 3 H 6 and C 2 H 6 over C 2 H 4 for MTO separation. • Zn-BDC-dmtrz delivers high C 3 H 6 uptake of 6.4 mmol g −1 and superior C 3 H 6 /C 2 H 4 IAST selectivity of 9.7. • Pore confinement and synergistic host–guest interactions jointly govern selective gas recognition. • One-step MTO purification by Zn-BDC-dmtrz yields polymer-grade C₂H₄ (>99.9%) and high-purity C₃H₆ (>99.5%). The efficient separation of propylene (C 3 H 6 ) from ethylene (C 2 H 4 ) and ethane (C 2 H 6 ) in methanol-to-olefins (MTO) product streams is of great industrial and economic significance, yet remains highly challenging due to their similar molecular sizes and physicochemical properties. Herein, we report a microporous zinc-based metal-organic framework, Zn-BDC-dmtrz, featuring a large pore volume, a confined pore aperture (∼5.6 Å), and a relatively nonpolar pore environment. These structural features enable preferential adsorption of C 3 H 6 and C 2 H 6 over C 2 H 4 , making Zn-BDC-dmtrz particularly suitable for the purification of MTO-derived hydrocarbon mixtures. At 298 K and 100 kPa, Zn-BDC-dmtrz exhibits a high C 3 H 6 uptake of 6.4 mmol g −1 , together with a C 3 H 6 /C 2 H 4 IAST selectivity of 9.7 and a separation potential (ΔQ) of 4.7 mmol g −1 , outperforming many representative MOF adsorbents reported for C 3 H 6 /C 2 H 4 separation. In situ FT-IR spectroscopy, GCMC simulations, and DFT-D calculations reveal that the superior adsorption of C 3 H 6 originates from synergistic pore confinement and favorable host-guest interactions within the framework. Dynamic breakthrough experiments further demonstrate that Zn-BDC-dmtrz enables the direct production of polymer-grade C 2 H 4 (>99.9%) and the recovery of high-purity C 3 H 6 (>99.5%) from binary and ternary mixtures representative of MTO effluents, with excellent recyclability over multiple adsorption-desorption cycles. This work highlights Zn-BDC-dmtrz as a promising adsorbent for one-step MTO product purification and provides design principles for porous materials combining confined pore sizes with chemically inert pore environments for challenging light-hydrocarbon separations. Schematic illustration of the one-step separation and purification of ethylene as well as recyclable recovery of high-purity propylene from MTO product streams benefiting from the unique structural advantages of Zn-BDC-dmtrz.

This study investigated the aggregation, dissolution, and sedimentation of Zn-doped CdTe quantum dots (CdTe: Zn2+ QDs) incubating with or without three different dissolved organic matter (DOM) in artificial freshwater and seawater as well as the underlying mechanisms. Our results found that water composition and DOM species significantly affected the above behaviors. Compared with in freshwater, bare QDs and QDs-DOM in seawater formed larger aggregates, released higher Cd2+ contents and sedimented faster. Under most circumstances, DOM inhibited QDs aggregation through enhancing electrosteric stabilization and accelerated QDs dissolution via promoting their contacts. Bovine serum albumin (BSA), humic acid (HA) and fulvic acid (FA) formed the largest, medium and smallest aggregates with QDs in freshwater, which were well agreed with the molecular weight of DOM and the stoichiometry of QDs-DOM interactions. QDs-FA released the largest content of Cd2+ in freshwater since FA has the strongest capacity of complexing QDs. In both artificial waters, HA and FA adsorption accelerated the sedimentation of QDs; while BSA impeded the sedimentation. Isothermal titration calorimetric experiments found that the major driving forces of all QDs-DOM interactions are hydrophobic forces. The stoichiometries for HA, FA and BSA binding to QDs are 6.3, 4.7 and 9.4, respectively. Results from multi-spectroscopic experiments suggested that the nano-form of QDs mainly interact with aromatic skeletons in HA rather than Cd2+. This study could shed light on predicting the fate and assessing the risk of QDs in aquatic environment.

As high emissivity emitters, traditional pseudobrookite ceramics are limited in thermal protection applications due to their structure degradation at high temperatures. In this work, a high-entropy pseudobrookite, (Mg,Co,Ni,Zn)Ti 2 O 5 , was designed, and CoTi 2 O 5 was selected as a single-component counterpart to evaluate the high-entropy effect on phase stability and emissivity. After heating at 1400 °C for 15 h, (Mg,Co,Ni,Zn)Ti 2 O 5 retained a single pseudobrookite phase with nearly unchanged emissivity, whereas CoTi 2 O 5 exhibited obvious phase degradation and emissivity deterioration. The higher 2.5–7 μm emissivity of (Mg,Co,Ni,Zn)Ti 2 O 5 was attributed to its narrower band gap (2.66 eV) and a higher oxygen vacancy fraction (56.87%). When coated on alumina-silica fiber fabric, the (Mg,Co,Ni,Zn)Ti 2 O 5 coating exhibited improved thermal-protection performance owing to its high infrared emissivity and reduced heat conduction, while maintaining good mechanical properties after heat treatment. These results demonstrate that (Mg,Co,Ni,Zn)Ti 2 O 5 is a promising high-emissivity ceramic for extreme thermal environments.

Electrolyzing water to produce hydrogen is currently one of the most attractive methods to alleviate the energy problem and environmental pollution. However, the slow oxygen production kinetics and complex mechanism have greatly limited its large-scale application. In our study, multiple types carbon-encapsulated C@M-Ni 2 P/NF (M = Co, Zn) were synthesized via impregnation and phosphidation process for the first time to address the need for environmentally friendly and high-performance bifunctional catalysts in electrocatalytic water splitting. Electrochemical tests revealed C@Co-Ni 2 P/NF present excellent oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) activity in an alkaline medium. The overpotentials were 196/255/294 mV at 10/50/100 mA·cm −2 (Tafel slope 34.20 mV·dec −1 ) for OER; the overpotentials were 199/311/363 mV for HER, which is outperforming C@Zn-Ni 2 P/NF, Ni 2 P/NF, and bare NF. The experimental analysis demonstrate that the improvement in performance for C@Co-Ni 2 P/NF is attributed to a “crack-texture interwoven” hierarchical pore structure and a protective surface carbon layer. In addition, when it is assembled into a two-electrode system, the electrolytic cell demonstrates excellent electrochemistry performance and acceptable durability under fluctuating power. In-situ Raman characterization demonstrated that the in-situ generated NiOOH and CoOOH, along with the material itself, synergistically catalyzed, resulting in the high activity of the catalyst. Density functional theory (DFT) analysis confirmed Co modification optimized water adsorption energy (-0.52 eV) and enhanced conductivity of C@Co-Ni 2 P/NF electrode by regulation of the d -band center. This study offers a promising and feasible strategy for developing robust and high-performance electrocatalysts.

A dual-stage strategy purified isoorientin from Thlaspi arvense L. leaves. • X-5 resin enabled efficient pre-enrichment of target flavonoids. • Fe 3 O 4 @SiO 2 @BA-Zn-MOFs selectively captured isoorientin via boronate affinity. • The magnetic adsorbent achieved rapid separation and good reusability. • Isoorientin purity reached 90.28% after integrated purification. Thlaspi arvense L. is a valuable industrial crop rich in bioactive flavonoids, specifically isoorientin and isovitexin. However, the efficient and selective separation of these isomers from complex plant matrices remains a significant challenge. In this study, a dual-stage purification strategy was developed by combining macroporous resin pre-enrichment with novel magnetic boronic acid-functionalized metal organic framework composites (Fe 3 O 4 @SiO 2 @BA Zn MOFs). The composite was synthesized via the coordinated assembly of 3,5-dicarboxyphenylboronic acid (BBDC) and zinc ions on magnetic silica cores. Systematic screening revealed X-5 resin as the optimal medium for preliminary enrichment, effectively removing major polar impurities. Subsequently, Fe 3 O 4 @SiO 2 @BA-Zn-MOFs were employed to selectively capture isoorientin via reversible boronate affinity. Under optimized conditions (pH 8.0, 120 min), the composite demonstrated high selectivity for isoorientin because of the formation of catechol-type ortho-dihydroxy moiety. The magnetic properties facilitated rapid solid liquid separation within 15 s. HPLC analysis revealed that the purity of isoorientin significantly improved from that of the crude extract to 90.28%. Furthermore, the magnetic adsorbent exhibited satisfactory stability and reusability, maintaining approximately 60% of its initial capacity after five consecutive cycles. This integrated approach provides an efficient and highly selective laboratory-scale strategy for the selective purification of high-value flavonoids from industrial crop byproducts and may provide a basis for future scale-up studies.

ZnO has been used as template to prepare and regulate the structures of functional nanomaterials. Due to the structural characteristics of Zn, its nanomaterials are generally considered inert. This study presents an innovative ZnO-templated synthesis of hollow N-doped carbon materials with atomically dispersed Zn single atoms (Zn SA/NC), where ZnO uniquely serves dual roles as both structural template and Zn precursor. The synthesized Zn SA/NC exhibits remarkable bifunctionality, demonstrating exceptional electrocatalytic activity for H₂O₂ reduction (detection limit: 3.7 µM, sensitivity: 1285.7 µA·mM⁻¹·cm⁻²) and intrinsic peroxidase-like activity for TMB oxidation. Leveraging these properties, we developed a dual-mode H₂O₂ detection platform integrating electrochemical and colorimetric readouts. The work challenges conventional views on Zn’s catalytic inertness by revealing that Zn-Nₓ sites enable efficient charge redistribution, while the hollow architecture enhances mass transport. This strategy bridges the gap between structural control and atomic dispersion in single-atom catalyst design. Graphical

Acetamiprid (ACE) can accumulate in the environment through the food chain, potentially endanger human health. In this experiment, zinc‑cobalt bimetallic metal organic framework (Zn/Co MOF) was synthesized and used to activate peroxymonosulfate (PMS) for the removal of ACE from water. The degradation efficiency of ACE could achieve approximately 96.93% after 90 min. Through the synergistic effect of Zn and Co bimetallic sites, ACE was degraded via a Fenton-like reaction, while reactive oxygen species (SO 4 ·- , ·OH, O 2 ·- , and 1 O 2 ) participated in the process. The high catalytic activity of Zn/Co MOF led to the degradation of ACE through the formation of a series of low-toxicity intermediates, and partial mineralization to CO 2 and H 2 O. In addition, Zn/Co MOF remained effective under broad pH conditions (pH 5–11) and temperatures (5–45 °C). This system had excellent degradation effects in actual water, with degradation rates of 95.42% and 95.18% after 90 min in the Pai River and Liren Lake, respectively. With its high catalytic performance, the Zn/Co MOF is expected to become an ideal catalyst that could be used to remove pesticide residues in water.

Zinc-ion batteries (ZIBs) have attracted widespread attention and experienced rapid development due to their high theoretical capacity, suitable voltage, and abundant zinc resources. However, their widespread deployment faces challenges like zinc dendrite growth and harmful side reactions. Hydrogel electrolytes offer a potential solution, effectively suppressing these issues and enabling flexible, wearable ZIBs for next-generation electronics. Herein, we present a dual-crosslinked hydrogel electrolyte (HPM) fabricated by free-radical polymerization that integrates a physically crosslinked network of the natural biopolymer hyaluronic acid (HA) with a chemically crosslinked polyacrylamide (PAM) framework. HA enhances mechanical robustness and interfacial adhesion via its abundant carboxylate and hydroxyl groups, coordinates Zn 2+ to modulate the solvation sheath and direct uniform Zn deposition, thereby effectively suppressing dendrite growth. As a result, Zn//Zn symmetric cells employing HPM demonstrated exceptional long-term cycling stability (1700 h at 1 mA cm −2 /0.5 mAh cm −2 ). Furthermore, Zn//HPM//PANI@CC full cells exhibited outstanding specific capacity (132.3 mAh g −1 at 0.2 A g −1 ) and remarkable cycle life (75% capacity retention after 2000 cycles at 2 A g −1 ). The practical viability of this electrolyte is highlighted by a functional flexible pouch cell incorporating HPM that successfully powered an LED display. This innovative dual-crosslinked HPM electrolyte design provides a valuable strategy for advancing high-performance flexible energy storage systems and electronic devices.

Metal-organic frameworks (MOFs) are used to derive inorganic material, which is an effective way to achieve high performance electrode materials for sodium-ion batteries (SIBs) and lithium ion batteries (LIBs). In this work, a novel orthorhombic bimetallic organic framework, [ZnCe(L 7 )·2H 2 O]n (termed as ZnCeL, L = 5-aminoisophthalic acid) with 3D open framework was synthesized via a simple solvothermal reaction. Then ZnSe/CeO 2 /RGO was successfully fabricated via pyrolysis and selenization of ZnCeL and graphene oxide (RGO) composites. In the hybrid, ZnSe with high theoretical specific capacity and CeO 2 with electrocatalytic property are wrapped by conductive RGO. Herein, ZnSe/CeO 2 /RGO displays excellent sodium and lithium-storage performances. It reveals a sodium storage capacity of 113.2 mAh g −1 after 2000 cycles at 2.0 A g −1 . Meanwhile, ZnSe/CeO 2 /RGO as an anode for LIBs delivers a reversible capacity of 675 mAh g −1 at 0.1 A g −1 after 200 cycles. The electrochemical kinetic analysis reveals that the redox reactions are dominated by pseudocapacitive behavior. The excellent performance reveals a bright prospect of the bimetallic organic frameworks derived inorganic material for energy storage.

Rational design and construction of highly efficient and durable non-noble-metal bifunctional catalysts for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) is crucial to promote the widespread implementation of rechargeable Zn-air batteries. Herein, a bifunctional catalyst comprising Co nanoparticles uniformly embedded in hollow nitrogen doped carbon tubes (Co@hNCTs) is fabricated by a facile tube-directed templating strategy. In this strategy, surfactant-treated polypyrrole (PPy) nanotubes serve as the structure-guiding templates for efficient capture of Co 2+ , realizing the in-situ growth of zeolitic imidazolate frameworks-67 (ZIF-67) nanocrystals on PPy nanotubes . Sodium laurylsulfonate acts as anionic surfactant to endow PPy nanotubes with functional electronegative surface and strong anchoring effect toward ZIF-67, playing the pivotal role in binding of ZIF-67 nanocrystals with PPy nanotubes potently. Consequently, the developed catalyst presents a superior ORR activity with the half-wave potential of 0.87 V excellent durability with only a 7 mV loss of half-wave potential after 5000 cycles. The catalyst also exhibits superior catalytic performance for OER. When serving as an air electrode in Zn-air batteries, a large power density of 149 mW cm −2 and long-term cyclability for over 500 h are realized in ambient air, implying the great potential in practical application.

An outstanding metal–organic framework sorbent (Zn-MOF) was prepared using Zn2+ and 3-amino-5-mercapto-1,2,4-triazole to eliminate toxic metal ions from water. Zn-MOF was detected via using Fourier-transform infrared (FTIR) spectroscopy, field-emission scanning electron microscopy (FESEM), Brunauer–Emmett–Teller (BET) analysis, and X-ray photoelectron spectroscopy (XPS). Zn-MOF is stable and has a very large surface area. The uptake properties of Zn-MOF were investigated. The maximum uptake capacity of Zn-MOF for Pb, Hg, and As ions was 1097, 32, and 718 mg/g, respectively. This was obtained at pH = 4, 5, and 6, respectively. The adsorption data is in good agreement with the Langmuir and pseudo-second-order rate models, indicating that the uptake process of Zn-MOF for toxic metal ions was a single layer uptake on a uniform surface via exchange of valence electrons. Thermodynamics shows that the uptake process is autogenic and endothermic. Zn-MOF can be reused at least 6 times. Mercury and lead strongly coordinated with Zn-MOF. The interaction between arsenic and Zn-MOF is weak chemical coordination and ion exchange. Zn-MOF has wide application prospects for toxic metal ion elimination.
