A Pd-ZnO@ZIF-8 heterostructured benzene gas-sensitive material was prepared. • The benzene sensor has a low detection limit, rapid detection and high stability. • Vision-olfactory robots have achieved intelligent inspection of leakage risks. Benzene (C 6 H 6 ) is a volatile organic compound with strong carcinogenicity, and achieving its rapid and sensitive detection is of great significance for environmental protection and the prevention and control of public health risks. In this study, a ternary heterostructure gas-sensing material composed of Pd-modified ZnO@ZIF-8 was proposed. The pre-concentration effect of ZIF-8, the catalytic sensitization of Pd nanoparticles, and the construction of the Schottky barrier at the Pd/ZIF-8 interface collectively endow the sensor with excellent detection performance. This sensor exhibits extremely high sensitivity at 375℃, with a rapid detection speed (response/recovery time of 2 s/2 s) and an extremely low detection limit (capable of reaching the ppb level). Meanwhile, based on this sensor, a pipeline condition monitoring platform was developed. On the mobile end, online monitoring of benzene leakage and graded early warning were realized. Furthermore, this detection system is integrated with robots. Through a combined olfactory and visual detection method, it enables intelligent inspection of the risks of gaseous and liquid benzene leakage. Therefore, the proposed Pd-ZnO@ZIF-8 sensor and its integrated monitoring platform offer a reliable and efficient solution for real-time benzene leakage detection, holding great promise for enhancing industrial safety and public health protection.

GOx@ZIF-90@CuCo-MOF composite was synthesized via synergistic self-assembly. • Bimetallic sites and ZIF-90 shell significantly enhanced nanozyme activity. • The GOx@ZIF-90@CuCo-MOF paper-based nanozyme sensor was fabricated for rapid and noninvasive glucose detection in saliva. • The sensor achieved a 13.5 μM detection limit within a 20-min reaction. Glucose biosensors are pivotal to diabetes management; however, traditional fingerstick blood collection methods are often challenging due to their invasiveness, pain, high cost, and inability to provide continuous monitoring. Here, we constructed a paper-based colorimetric sensing platform using a multifunctional metal–organic framework (MOF) composite system to enable rapid, noninvasive detection of glucose in saliva. This platform utilized a CuCo-MOF framework, loaded with glucose oxidase (GOx) and ZIF-90 via a synergistic self-assembly mechanism, to catalyze the colorimetric reaction of H 2 O 2 and tetramethylbenzidine (TMB). The synergistic effect of the composite significantly enhanced the overall catalytic efficiency, enabling a sensitive response to glucose levels in saliva. Using ImageJ, color images captured with a smartphone were analyzed using RGB color channels to quantitatively determine glucose levels in saliva. The detection time was 20 min, with a detection limit (LOD) of 13.5 μM and a linear range of 50–2000 μM. This platform offered advantages with the absence of blood sample collection, ease of operation, and visual response. It provided new material strategies and design ideas for developing portable, non-invasive blood glucose monitoring technology.

Biomimetic ZIF-L/MXene were prepared by a facile two-step synthetic route. • Microflower structure favors light harvesting and active site exposure. • MXene can expand the photoresponse into the near-infrared region. • ZIF-L/MX-0.8 achieves efficient photodriven CO2 fixation under ambient conditions. • The photothermal/photocatalytic synergistic mechanism was explored. Solar-driven carbon dioxide (CO 2 ) transformation into valuable carbon-based products is of high significance for simulating natural carbon cycling. However, the ongoing challenge lies in the design of photocatalysts for achieving efficient CO 2 conversion. In this study, inspired by natural wisdom, ZIF-dia/MXene microflowers are successfully constructed through [Zn(NH 3 ) 4 ] 2+ -induced self-assembly of Ti 3 C 2 T x MXene (T x = –F, –OH, =O) sheets followed by the in-situ growth of ZIF-DIA. Remarkably, the optimized ZIF-dia/MX-0.8 serving as a solar-triggered photothermal and photocatalytic bifunctional platform was found to catalyze the coupling of CO 2 and epichlorohydrin, with a cyclic carbonate yield of 98% under full spectrum illumination for 6 h, significantly surpassing the single components. Specifically, the hierarchical flower-like superstructure consisting of ZIF-dia and MXene sheets can favor light absorbance via multiple reflection and facilitate the exposure of active sites and mass transfer. In addition, this ZIF-dia/MXene composite can absorb the light covering the entire visible region owing to the presence of MXene, thereby enhancing the photothermal conversion. Furthermore, experimental results reveal that the CO 2 cycloaddition with epoxide over ZIF-dia/MX-0.8 is proved to be the synergy of photothermal catalysis and photocatalysis. This work enriches the design of MOF-containing photocatalysts, opening a unique and sustainable way to solve global environmental issues.

The development of high-performance, easily tunable, and multifunctional electromagnetic materials remains a challenge in the field of microwave absorption. To address key issues such as impedance mismatch and insufficient loss capacity in absorbers, this paper proposes a dual-strategy approach based on solvent-mediated competitive coordination and reaction-driven modulation for the design and preparation, a tunable Zeolitic Imidazolate Framework-67 (ZIF-67) shell was successfully constructed on the surface of flake carbonyl iron (FCI). FCI@ZIF-67-d achieves an effective absorption bandwidth (EAB) of 8.37 GHz at 1.59 mm, while FCI@ZIF-67-s exhibits a minimum reflection loss (RLmin) of −54.00 dB at 4.48 GHz. In addition, the combination of first-principles (DFT) and electromagnetic finite element simulation techniques with experimental results has further elucidated the loss mechanism of FCI@ZIF-67. When the shell transitions from a three-dimensional (3D) dodecahedral structure to a two-dimensional (2D) nanosheet, the nanosheet shell effectively releases the π–π* bonds constrained within the 3D framework, significantly enhancing the conduction and dielectric polarization capabilities of the material. This enhancement effect strongly couples with the magnetic loss provided by the FCI core, synergistically optimizing impedance matching and attenuation mechanisms in the low-frequency range. This research provides a clear physical framework for understanding microwave absorption through dimensional control and introduces a low-temperature, frequency-customizable design strategy for advanced absorbers.

Current adsorbents for bisphenol A (BPA) require complex preparation and relatively low adsorption capacities. Here, a high-performance adsorbent (Fe-N-C) was synthesized from iron-modified zeolite imidazole frameworks-8 (ZIF-8) via pyrolysis. With an exceptionally high specific surface area of 1565.15 m 2 ·g −1 , Fe-N-C removed 90% of BPA within 10 min and achieved adsorption equilibrium within 3 h. Furthermore, Fe-N-C exhibited a maximum BPA theoretical adsorption capacity of 877.45 mg·g −1 (288 K). The adsorption kinetics and isotherms conform to pseudo-second-order kinetics and the Langmuir model. Fe-N-C also demonstrated excellent performance across a wide pH range (4–10) and in complex water matrix. The high adsorption capacity was primarily attributed to π-π interactions, along with hydrogen bonding, electrostatic interactions, and hydrophobic interactions. Notably, in addition to efficiently adsorbing BPA, Fe-N-C exhibited a high selectivity toward organic compounds with two benzene rings by π-π interactions, such as bisphenol B (BPB), 2,2-bis (4-aminophenyl) propane (BAPP) and diclofenac (DCF) due to the mediation of graphitized microdomains. This study provides a simple route to prepare high-capacity N-doped carbon adsorbents for the selective and rapid adsorption of specific structural pollutants.

Hydrogen is an ideal safe and clean energy source, which can be produced by the electrocatalytic hydrogen evolution reaction (HER). The high overpotential of HER is one of bottlenecks for practical application, thus efficient and stable electrocatalysts, especially inexpensive electrocatalysts, are being vigorously developed to facilitate the reaction. Herein, we report the rational synthesis of a non-noble transition metal electrocatalyst via combined self-assembly and ion-exchange strategy. Zeolitic Imidazolate Framework-67 (ZIF-67) was in-situ grown on the surface of polypyrrole-derived nitrogen-doped carbon nanotubes (N-CNT) through a self-assembly method and then ZIF-67 was transformed into a CoMo layered double hydroxide (CoMo-LDH) through an ion-exchange reaction. As a result, a nanocomposite with N-CNT as the core and CoMo-LDH as the shell (N-CNT@CoMo-LDH) was successfully synthesized. The optimal N-CNT@CoMo-LDH exhibits excellent HER performance with a low overpotential of 86 mV at 10 mA cm −2 in 1 M KOH, superior to ZIF-67, CoMo-LDH, N-CNT@ZIF-67 and many reported LDH-based electrocatalysts. Additionally, the N-CNT@CoMo-LDH maintains approximately 86% of its initial current density after 24-h continuous test, with an overpotential increase of only 9 mV after 3000 cycles. The improved electrocatalytic HER performance is primarily attributed to the synergistic interaction between Mo 6+ and Co 2+ /Co 3+ , facilitating the formation of active sites, and N-CNT as core to enhance electron transport rates and inhibit the stacking of CoMo-LDH nanosheets, thus exposing more active sites of CoMo-LDH. Furthermore, its HER is confirmed to be the Volmer-Heyrovsky mechanism. This work provides a promising pathway for synthesizing highly efficient and stable electrocatalysts based on inexpensive non-noble metals.

A straightforward method using the solid-solid thermal (SST) method to synthesize Cu@ZIF-8. • A green and environmental approach to large-scale engineering synthesis. • A feature surface structure of Cu@ZIF-8 as an effective antibacterial and robust material for environmental issues. • A new pathway on Cu@ZIF-8 interacts with bacterial membranes, resulting in cell death. A straightforward solid-solid thermal (SST) method was developed to incorporate copper into a zeolitic-imidazole framework-based zinc compound, resulting in Cu@Zn-ZIF-8. This strategy enables the synergistic integration of copper within the zinc-imidazolate host framework. The process achieves a maximum copper content reached 30%, a level unattainable by traditional solvothermal techniques, and exhibits uniform, robust copper incorporation. This one-step, solvent-free approach significantly increases product yield while maintaining a low metal-to-ligand ratio. The resulting Cu@Zn-ZIF-8 displays a highly crystalline structure with increased copper density. This method is readily scalable up to 1000 times the laboratory scale without compromising material quality. Furthermore, surface-generated reactive oxygen species (ROSs) on Cu@Zn-ZIF-8 significantly improve antibacterial efficacy (>99.9%) against both Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus, outperforming unmodified ZIF-8 by 16–20 times. The hydrophobic properties of Cu@Zn-ZIF-8 also make it particularly well-suited for high-moisture environments. Download: Download high-res image (360KB) Download: Download full-size image

en Thermally driven hydrogenation of CO 2 to light olefins (C 2 = –C 4 = ) using metal oxide-zeolite tandem catalysts is an effective strategy for achieving carbon neutrality. However, progress in this area is constrained by zeolite pore transport limitations, acid-site inactivation, and surface carbon poisoning. To address these issues, we replaced conventional zeolites with La-modified ZIF-8 and combined it with hollow cubic In 2 O 3 to develop a novel In 2 O 3 -La-ZIF-8 tandem catalyst. Our study investigates the effects of the hydrothermal reaction temperature used for synthesizing In 2 O 3 and the La content in ZIF-8 on catalytic performance. We also found that the oxygen vacancy (O V ) concentration in In 2 O 3 can be substantially regulated by adjusting the hydrothermal temperature. The In 2 O 3 sample with the highest O V concentration not only promotes the formation of reaction intermediates but also markedly reduces the energy barrier of the rate-determining step in methanol synthesis. Comprehensive characterization and simulation analyses indicate that La incorporation enhances the thermal stability of ZIF-8, improves its ability to adsorb and activate reaction intermediates, and effectively adjusts its acid-base properties. Under a reaction pressure of 3.0 MPa and a temperature of 360°C, the hollow cubic In 2 O 3 -La-ZIF-8 tandem catalyst achieves 23.5% CO 2 conversion with 65.3% C 2 = –C 4 = selectivity. 摘要 zh 利用金属氧化物-分子筛串联催化剂 , 通过热驱动将CO 2 转化为低碳烯烃(C 2 = –C 4 = ) , 是实现碳中和的有效策略。然而 , 该领域的发展受到分子筛孔道传质限制、酸性位点失活及表面积碳等问题的制约。为解决这些难题 , 本研究以La修饰的ZIF-8替代传统分子筛 , 并将其与空心立方体In 2 O 3 相结合 , 开发了一种新型的In 2 O 3 -La-ZIF-8串联催化剂。系统探究了In 2 O 3 水热合成温度以及ZIF-8中La含量对催化剂性能的影响。通过调节水热温度可显著调控In 2 O 3 中的氧空位浓度 , 具有最高氧空位浓度的In 2 O 3 样品不仅能促进反应中间体的生成 , 还可显著降低甲醇合成过程中决速步骤的能垒。综合表征与模拟分析表明 , La的引入增强了ZIF-8的热稳定性 , 提升了其对反应中间体的吸附与活化能力 , 并有效调节了其酸碱性质。在3.0 MPa、360°C的反应条件下 , 空心立方In 2 O 3 -La-ZIF-8串联催化剂上实现了23.5%的CO 2 转化率与65.3%的低碳烯烃选择性。

Polydimethylsiloxane (PDMS) sponges exhibit low oil adsorption capacity due to their monolithic pore structure and limited surface area. Here, we present SDS-ZIF-67/PDMS composite sponges that overcome these limitations. ZIF-67 particles are incorporated into the PDMS matrix via a soft-templating approach, creating a submicron hierarchical pore structure and increasing the number of accessible adsorption sites. Surface functionalization with sodium dodecyl sulfate (SDS) introduces long alkyl chains, modulating surface chemistry and enhancing selective affinity for oil molecules. The composite sponge exhibits a water contact angle of 135°, reaches adsorption equilibrium within 6 min, and achieves 96% separation efficiency for various oils and oil–water mixtures. After 15 adsorption–desorption cycles, 87% of the initial adsorption capacity is retained, demonstrating exceptional cyclic stability. These findings underscore the potential of SDS-ZIF-67/PDMS composite sponges for efficient treatment of oily wastewater.

We prepared BAE@ZIF-8 nanocomplexes targeting as novel encapsulation material. • BAE@ZIF-8 nanocomplexes improved temperature and optical stability of anthocyanin. • The composite films achieved lower WVP and high opacity for superior UV shielding. • The film based on BAE@ZIF-8 nanocomplexes effectively enhanced color stability. In this study, a pH-sensitive material BAE@ZIF-8 nanocomplex with enhanced photo-thermal stability using blueberry anthocyanin (BAE) in combination with the metal-organic framework ZIF-8 was prepared. Further, a novel intelligent indicator film was prepared as a pH core indicator using the solution casting method. BAE@ZIF-8 significantly improved the temperature and optical stability of BAE. The encapsulation within ZIF-8 simultaneously improved stability without compromising pH/ammonia responsiveness, a critical trade-off often encountered in anthocyanin-based indicators. The tensile strength of the film was enhanced to 1.12 MPa, and the WVP and WS were reduced to 1.04 × 10 −7 g m/m 2 .Pa.s and 30.19% by doping BAE@ZIF-8 into the WG and AP matrices, while the UV shielding properties of the film were effectively improved. Compared to the WG-AP/B-ZIF-8 films, the BAE@ZIF-8 nanocomplexes exhibited more homogeneous dispersion and excellent retention of structural integrity. The BAE@ZIF-8 gluten film enhanced color stability, providing a foundation for improved intelligent monitoring materials. Download: Download high-res image (340KB) Download: Download full-size image

Tumor microenvironment-responsive nanomedicines offer significant advantages in enhancing treatment specificity and minimizing systemic toxicity. Nevertheless, the therapeutic efficacy of single-modality treatments is often limited by tumor heterogeneity, necessitating the development of multimodal nanoplatforms capable of leveraging multiple tumor microenvironment characteristics for efficient synergistic therapy. In this study, a multifunctional nanocomposite comprising cobalt zeolitic imidazolate framework-67-encapsulated Au nanodendrites coloaded with tirapazamine is developed for tumor-selective therapy. To address the inherent limitations of traditional preclinical models, human healthy and colorectal cancer organoids are utilized as advanced in vitro assessment platforms. Mechanistic studies revealed that multibranched Au nanodendrites disrupt cellular membrane integrity, whereas the acidic condition induces the degradation of the cobalt zeolitic imidazolate framework-67, facilitating targeted drug release. These combined actions synergistically amplify intracellular reactive oxygen species generation and disrupt mitochondrial membranes, leading to the selective elimination of tumor cells. This work presents a highly efficient, tumor microenvironment-responsive nanotherapeutic platform and demonstrates the critical value of organoid-based evaluation systems in advancing the clinical translation of targeted nanomedicines.

In vitro : CPP reduced 143B cell viability by ~50% at 30 µg/mL with low toxicity to normal osteoblasts. • In vivo : CPP reduced xenograft tumor volume by ~80% and showed good biosafety in histology and serum tests. • Mechanism: CPP induced ROS accumulation, GSH depletion, SLC7A11/GPX4 downregulation, and ferroptotic mitochondrial damage. Ferroptosis induction represents a promising antitumor strategy, yet osteosarcoma cells frequently resist ferroptosis through the PSMD14-mediated stabilization of SLC7A11. Here, we report an acid-responsive cobalt-doped ZIF-8 nanoplatform loaded with 1, 10-phenanthroline and coated with PEG (denoted as CPP) that simultaneously amplifies oxidative stress and dismantles the PSMD14/SLC7A11 antioxidant axis. Upon exposure to the acidic tumor microenvironment, the ZIF-8 framework degrades, releasing Co 2+ ions that catalyze Fenton-like reactions to generate hydroxyl radicals (•OH) and initiate lipid peroxidation. Concurrently, 1, 10-phenanthroline chelates the catalytic Zn 2+ of PSMD14, abolishing its deubiquitinase activity and thereby promoting ubiquitin-dependent degradation of SLC7A11, which depletes intracellular glutathione (GSH). Physicochemical characterization confirmed the successful construction of CPP nanoparticles (~100 nm) with a drug loading efficiency of 14.76% and pH-triggered Co 2+ release. In vitro , CPP was efficiently internalized by 143B osteosarcoma cells and exhibited dose-dependent cytotoxicity with markedly elevated reactive oxygen species (ROS), malondialdehyde (MDA) accumulation, lipid peroxidation, mitochondrial depolarization, and downregulation of SLC7A11 and GPX4, collectively supporting ferroptosis. CPP also significantly suppressed osteosarcoma cell invasion. In a subcutaneous 143B xenograft model, intravenous CPP administration reduced tumor volume by approximately 80% relative to controls, with pronounced tumor necrosis, proliferation inhibition, and decreased SLC7A11/GPX4 expression in tumor tissues, while maintaining favorable biosafety. These findings establish CPP as a dual-action nanoplatform for ferroptosis-based osteosarcoma therapy.
