Heavy metal ions (HMIs) pollution has become a significant threat to the global environment and agricultural safety. The accumulation of these metals in soil and crops may have a serious impact on human health. Therefore, it is of utmost importance to develop a rapid, reliable and highly sensitive detection platform. A self-supporting electrochemical sensor based on an interpenetrating twin ZIF-8/carbon nanofiber aerogel (ZIF-8(IT)/CNT-NFCA) was developed for the sensitive and simultaneous detection of Cd 2+ and Pb 2+ in soil and crop samples. Unlike traditional electrodes, this independent architecture eliminated the need for rigid conductive substrates and complex surface modifications. The freestanding 3D nanofiber network, reinforced by carbon nanotubes and embedded with twin-structured ZIF-8, provided a mechanically stable and highly conductive matrix with abundant accessible active sites. Under optimized differential pulse anodic stripping voltammetry conditions, the sensor exhibited wide linear ranges of 0.10–100 μg·L −1 for both Cd 2+ and Pb 2+ , with low limit of detection (LOD) 0.09 μg·L −1 and 0.05 μg·L −1 , respectively. Benefiting from the integrated structure, the sensor showed enhanced signal stability and resistance to electrode delamination under real sample testing. Applications in actual rice, wheat, soil, and water samples demonstrated high recovery rates and validated the sensor's reliability. This study provides a robust and portable sensing platform, offering promising prospects for field-deployable heavy metal ion monitoring in environmental and agricultural safety.

Adsorption-electrocatalytic oxidation is a promising technology for organochlorine removal; however, its practical application is hindered by electrode limitations in activity, stability, and mechanistic understanding. In this study, a copper-doped ZIF-8/multi-walled carbon nanotube composite electrode (Cu-ZIF-8/MWCNTs/CC) was innovatively designed. Adsorption-electrochemical batch experiments were conducted to systematically investigate the degradation behaviors of three typical organochlorine contaminants: 2,4-dichlorophenol (2,4-DCP), triclosan (TCS), and chloramphenicol (CAP), using MOF-based electrodes. The results demonstrate that compared to the undoped ZIF-8/MWCNTs/CC, the incorporation of Cu introduced additional mesoporous structures and Cu-N coordination bonds, which effectively enhanced adsorption performance based on the size-matching effect and d-band center theory. Furthermore, the highly reversible and kinetically rapid Cu 2 + /Cu + redox couple served as an efficient mediator for charge transfer, thus promoting the synergistic adsorption and electrochemical degradation of organochlorine contaminants. Notably, the material maintained considerable removal efficiency even under competitive conditions in multicomponent systems. Mechanistic investigation demonstrated that hydroxyl radicals (·OH) preferentially attacked critical chemical bonds (including C-Cl, ether, and amino groups) in accordance with density functional theory (DFT) predictions. This reaction pathway resulted in the generation of less toxic intermediates that were eventually mineralized into CO 2 and H 2 O. The ecological structure-activity relationships (ECOSAR) model further confirmed the low acute and chronic toxicity of the major degradation products. Moreover, the electrode maintained high removal efficiency across multiple consecutive cycles, demonstrating excellent stability and reusability. Collectively, this work proposes a novel strategy for the synergistic adsorption and electrocatalytic removal of organochlorine contaminants; thereby highlighting its significant potential for practical application.

ZIF-8-decorated biochar hold great potential for heavy metal contaminated wastewater remediation due to the superior adsorption performance of ZIF-8. However, the inevitable blockage of nature pore during preparation restricted the enhancement of adsorption performance and further practical applications. Herein, a novel Zn(NO 3 ) 2 activation-combined in-situ growth strategy was established for porous ZIF-8-decorated biochar (AI-BC@ZIF-8) preparation, this strategy enables the synergistic promotion of porous structure and distribution of ZIF-8 for adsorbent. The AI-BC@ZIF-8 exhibited an excellent adsorption capacity of 249.63 mg/g for Pb, achieving removal efficiency of 99.8% for conventional 50 mg/L Pb-containing wastewater. The adsorption process conforms to the pseudo-second-order kinetic model and the Langmuir isothermal model, indicating the monolayer chemical adsorption mechanism. The results of FTIR, BET and XPS analyses indicate that the adsorption mechanism of AI-BC@ZIF-8 is electrostatic interaction, N-coordination, precipitation, ion-exchange and pore-filling. Overall, this adsorbent demonstrates outstanding adsorption performance, showing its great potential in efficient and low-cost water purification. This work provides a viable strategy for the synthesis of highly porous and efficient ZIF-8-decorated biochar for heavy metal removal from wastewater.

Seamless integration at the interphase is the foremost issue delaying the development of high-performance mixed matrix membranes (MMMs). Here we report an in-situ crosslinking strategy to effectively integrate the solvent-assisted linker exchange (SALE)-derived ZIF-8 with amidoxime-modified PIM-1 (AOPIM-1) for the challenging propylene/propane separation. In this crosslinking system, the AOPIM-1 polymer matrix can chemically anchor to the surrounding ZIF-8 fillers, promoting the formation of core-shell-like structures, thereby improving interfacial compatibility and filler dispersion. As a result, both high propylene permeability and high selectivity are readily achieved at a low filler loading (10 wt%), significantly surpassing the single- and mixed-gas upper bounds. Additionally, we demonstrate a contraction behavior in ZIF-8 unit cells that correlates with filler loading. Despite the persistence of excellent filler dispersion in highly loaded MMMs, excessive unit cell contraction leads to undesirable interfacial debonding and blocked transport through filler, ultimately deteriorating separation performance. Thus, the in-situ crosslinking imparts a ‘double-edged sword’ effect―simultaneously ensuring superior interfacial compatibility while inducing controllable ZIF-8 lattice contraction. These insights are expected to provide valuable guidance for the rational design and performance optimization of MOF-based MMMs via in-situ crosslinking.

To address the issues of poor cycling stability and unrealized theoretical capacity of layered molybdenum disulfide (MoS 2 ) as an anode material—caused by severe volume expansion during charge/discharge processes—we innovatively propose a "partial carbonization" modification strategy for ZIF-8 templates. This approach successfully constructs a ZnS/NC "dodecahedral nursery" rich in active sites. Benefiting from the abundant anchoring sites provided by this structure, MoS 2 can uniformly and firmly "take root" on the "nursery" via Mo–N bonds, ultimately forming a composite material (ZnS/NC@MoS 2 ) in which MoS 2 nanoflowers uniformly coat the dodecahedral framework. This composite effectively mitigates the volume expansion of MoS 2 and enhances overall structural stability. Moreover, the zinc retained by the partial carbonization strategy, after sulfidation, contributes additional capacity via conversion reactions, further enhancing the material's electrochemical performance. Specifically, when used as an anode for lithium-ion batteries (LIBs), it maintains a specific capacity of 895.64 mAh g −1 after 1200 cycles at 2 A g −1 ; for sodium-ion batteries (SIBs), its specific capacity increases from 348 mAh g −1 to 510 mAh g −1 after 500 cycles at 1 A g −1 .

Magnesium-based anode materials have attracted significant attention in the energy storage domain because of their high theoretical capacities and low electrochemical potentials. However, in conventional electrolyte systems, magnesium metal electrodes dynamically generate an ion-blocking surface layer, resulting in prominent voltage polarization, which severely limits their practical applications. In this study, ZIF-8/carbon nanotubes (CNTs) coatings were used to modify the anodes of magnesium batteries. Compared with the unaltered magnesium battery, the voltage lag time of the ZIF-8/CNTs coating was shortened from 4 s before modification to 0.26 s, and the battery impedance was lowered by two orders of magnitude. The duration of the discharge platform was increased from 4 h before modification to 6–10 h, the anode utilization rate was more than doubled, and the specific energy density was significantly enhanced compared with the battery before modification. The mechanism indicates that the ZIF-8/CNTs coating can limit the infiltration of corrosive substances, extend their transmission path, and offer more effective protection to the magnesium anode. The incorporation of CNTs improves the conductivity of the battery, and it significantly improves the electrochemical performance of the magnesium battery.

Tetracyclines (TCs), widely used in livestock farming, accumulate in ecosystems and pose health risks due to their persistence. Existing detection methods suffer from high cost, complex procedures, and insufficient specificity. Herein, a dual-emission fluorescent composite (CDs@ZIF-8) was designed by encapsulating carbon dots (CDs) into a zeolitic imidazolate framework-8 (ZIF-8). The composite material exhibits distinct dual emission peaks at 332 nm (ZIF-8) and 492 nm (CDs), and achieves ratiometric fluorescence sensing and differentiation between two structurally analogous antibiotics tetracycline (TC) and chlortetracycline (CTC) by quenching the ZIF-8 peak and enhancing the CD peak. The sensor achieves low detection limits of 7.13 nM for TC and 7.25 nM for CTC, with excellent selectivity and anti-interference capability over other antibiotics. A colorimetric logic gate and smartphone-based RGB analysis platform were developed for visual discrimination and quantitative detection, demonstrating high accuracy in real-sample analysis. This work provides a robust, low-cost strategy for on-site monitoring of TC antibiotics.

ZIF-8-derived carbon materials possess great advantages in the field of electrochemical adsorption due to their abundant porous structures, excellent specific surface areas, and good electrical conductivity. The efficient separation and capture of bromide ions (Br − ) from brine systems represent a critical pathway to achieving high-efficiency utilization of brine resources and environmental protection. In this study, a nitrogen (N)-doped ZIF-8-derived carbon material (NC-800) was synthesized via high-temperature calcination at 800 °C, and its performance in separating and capturing Br − from brine was systematically investigated. Electrochemical test results showed that the NC-800 membrane electrode achieved a maximum intercalation capacity of 115.65 mg·g −1 for Br − at an oxidation voltage of 1.0 V . Moreover, the captured Br − could be successfully converted into elemental bromine (Br₂) through carbon tetrachloride (CCl₄) extraction, realizing the resource recovery of Br − . Cyclic stability tests indicated that after 10 adsorption-desorption cycles, the maximum intercalation capacity of the electrode remained at 57 mg·g −1 , demonstrating excellent cyclic reusability. Systematic characterizations were conducted to analyze the microstructure of NC-800 and the adsorption mechanism of Br − . Combined with electrochemical performance analysis, the effects of different operating conditions on Br − adsorption performance were examined. Density functional theory (DFT) was employed to verify the adsorption mechanism of Br − on NC-800, and the results confirmed that nitrogen doping significantly enhances the Br − adsorption capacity of porous carbon materials. This study deepens the understanding of the “physical-chemical synergistic adsorption mechanism” during Br − separation by the NC-800 material, offering new insights for the development of sustainable bromine resource recovery technologies.

To address the need for rapid desorption in protein adsorption applications, we developed and characterized magnetic core–shell nanoparticles composed of a zeolite imidazolate framework-8 (ZIF-8) coating on magnetite (Fe 3 O 4 ) cores (Fe 3 O 4 @ZIF-8). This nanostructure integrates the pH-sensitive properties of ZIF-8 with the magnetic responsiveness of Fe 3 O 4 , enabling rapid separation within one minute via an external magnetic field. In the synthesis of Fe 3 O 4 @ZIF-8, the particle size of the ZIF-8 shell was found to increase concurrently with the molar ratio of zinc nitrate hexahydrate to 2-methylimidazole. The resulting shells were uniformly distributed on the surface of the Fe 3 O 4 cores. Furthermore, a positive correlation was observed between the ZIF-8 particle size and the adsorption capacity for histidine-rich proteins. In adsorption experiments using bovine hemoglobin (BHB) as a model protein, Fe 3 O 4 @ZIF-8 achieved an adsorption capacity of 1013.5 mg/g within 3 min, representing 87% of its maximum adsorption potential. Saturation adsorption, with a capacity of 1164.3 mg/g, was reached within 8 min. Importantly, the pH-responsive nature of the ZIF-8 component facilitated highly efficient desorption. A high release efficiency of 90% was achieved in just 1 min using a phosphate buffer at pH 5.2. This dual pH- and magnetic-responsive system demonstrates significant potential for applications requiring fast and controllable protein adsorption and desorption, positioning it as an ideal tool for targeted protein recovery in various biochemical and industrial processes.

Poor interfacial stability and dendrite penetration at the lithium metal anode interface are critical bottlenecks hindering the practical application of garnet-type solid electrolytes, despite their high intrinsic ionic conductivity. Herein, we resolve this long-standing trade-off by designing a hierarchical sandwich heterostructure. This architecture comprises a dense Li 6.4 Ga 0.2 La 3 Zr 2 O 12 (C-LGLZO) ceramic scaffold sandwiched between two ZIF-8@SiO 2 /PVDF-HFP (ZSPH) composite interfacial layers. The resulting composite solid electrolyte (CSE) C-LGLZO/ZSPH exhibits exceptional electrochemical properties: a high Li + transference number (t Li+ = 0.77) and an outstanding ionic conductivity of 1.31 × 10 −3 S cm −1 at 30 °C. Mechanistically, while the robust central C-LGLZO scaffold provides a continuous Li + pathway and physically blocks dendrites, the honeycomb-like porous ZSPH interfacial layers homogenize the interfacial electric field and promote a stable solid electrolyte interphase (SEI). This synergistic design endows the CSE with a wide electrochemical stability window (4.8 V vs. Li/Li + ) and enables stable Li plating/stripping for over 1000 h. Furthermore, cells using a LiFePO 4 cathode retain 76.3 % of their capacity after 500 cycles at 0.5C, demonstrating exceptional high-rate cycling stability. This work offers a versatile architectural strategy for engineering robust solid-state batteries (SSBs).

Synergistic coating design combining ZIF-8 and PDMS on a porous PI substrate. • Integrated multifunctionality enabling oil-water separation, photocatalytic degradation, and anti-bioadhesion. • Exceptional separation performance with a water contact angle of 162.8° for various oil-water mixtures. • Outstanding environmental durability demonstrated against mechanical abrasion, UV aging, and acid/alkali corrosion. The treatment of wastewater containing oils and organic pollutants remains a critical environmental challenge. Traditional separation membranes often lack the multifunctionality needed for simultaneous separation, degradation, and antifouling. In this study, a robust superhydrophobic composite membrane was fabricated via a facile solution-impregnation method, in which zeolitic imidazolate framework-8 (ZIF-8) nanoparticles were integrated with polydimethylsiloxane (PDMS) onto a porous polyimide (PI) substrate. The designed coating synergistically combines the micro-/nano-scale roughness of ZIF-8 with the low surface energy of PDMS, endowing the membrane with a water contact angle of 162.8 ± 0.3° and a sliding angle of 3.0 ± 0.4°. The composite membrane demonstrates high-efficiency separation of various oil-water mixtures (>95% efficiency, flux >9000 L·m −2 ·h −1 ), effective photocatalytic degradation of methylene blue (MB) under ultraviolet (UV) light (93.7% within 2.5 h), and excellent anti-bioadhesion performance against Chlorella vulgaris. Moreover, the membrane retains its superhydrophobicity after mechanical abrasion, tape peeling, UV aging, and exposure to acidic/alkaline environments, confirming outstanding durability. This work presents a scalable strategy for developing multifunctional PI-based membranes with integrated separation, catalytic, and antifouling properties, showing promising potential for practical water remediation applications.

An adsorption-triggered mechanism was proposed for on-demand release. • Acidic sites on ZSM-5/ZIF-8 possess stronger adsorption energy for biogenic amines than CA. • The mechanical and gas barrier of film were improved after introducing ZSM-5/ZIF-8. • The developed packaging effectively prolonged fish preservation at 4 °C. Active packaging with on-demand release capability has attracted increasing interest in food preservation; however, the delayed response of active agents often compromises protection during the early stage of spoilage. In this work, an adsorption-triggered release strategy was proposed by incorporating cinnamaldehyde (CA)-loaded ZSM-5/ZIF-8 nanoparticles (CA@ZSM-5/ZIF-8) into a sodium alginate (SA) matrix. Owing to the strong affinity of biogenic amines toward the adsorption sites of ZSM-5/ZIF-8, low concentrations of histamine could competitively displace the preloaded CA, thereby enabling an early and responsive release behavior. In the absence of histamine, the cumulative release of CA from the composite film remained below 10% within 12 h, whereas it increased to approximately 60% in the presence of 5.0 mM histamine. Meanwhile, the optimized film exhibited improved tensile strength (54.6 MPa), water vapor barrier performance (0.86 × 10 −10 g·m·m −2 ·s −1 ·atm −1 ), UV-shielding capability, and water resistance. The film also showed pronounced antioxidant activity (91.4%), sustained antibacterial effects against E. coli and S. aureus , and favorable biodegradability. When applied to fish preservation, the optimized film effectively extended the refrigerated shelf life to 6 days at 4 °C. This study provides a novel paradigm for on-demand release in intelligent food packaging.
