The efficient extraction of uranium from seawater plays an important role to guarantee a sustainable nuclear energy industry. Zr-based metal-organic frameworks (MOFs) are promising uranium adsorbents due to their high stability, customizable functionality and adjustable topological structure. In this study, Zr based MOF-808 with tunable phytic acid (PA) functionalization (MOF-808-PA1 and MOF-808-PA2) were prepared. The modulation of PA modification significantly promoted the uranium extraction of MOF-808 with the saturated adsorption capacity reaching 423.89 mg/g and adsorption equilibrium achieved in 15 min in aqueous solution. Impressively, MOF-808-PA2 exhibited superior selectivity towards uranium with the distribution coefficient up to 9.2 × 10 5 mL/g, which overwhelms other competitive ions in simulated seawater. After adsorption in real seawater for 28 days, uranium capture capacity of MOF-808-PA2 reached 7.85 mg/g, 8 times higher than that of vanadium. DFT simulation indicated that the excellent seawater uranium extraction performance originated from the strong affinity between abundant P-O/P=O and uranyl ions. This work highlights the design of high-performance uranium adsorbents based on functional group modification in MOFs system.

Polysiloxanes, widely used in antifouling applications, confront significant challenges due to their damage in complex service environments, making the development of self-healing polysiloxanes (SHS) imperative. Current self-healing polymers underutilize silicone components, and intrinsic self-healing pure polysiloxanes, especially those integrated with functional fillers, remain largely unexplored. In this study, we developed a self-healing antifouling polysiloxane system through low-temperature green synthesis of H-bond-enriched polysiloxanes, combined with the synergistic photocatalytic/contact-killing effects of MIL-125-NH₂ and ionic liquid. The material achieves instantaneous self-healing at room-temperature after fracture through segmental mobility and hydrogen bond reconfiguration, with a final healing efficiency of up to 80.2 %. It demonstrates exceptional antibacterial activity under light irradiation while effectively reducing bacterial adhesion in dark environment. Moreover, it exhibits exceptional thermal stability up to 370 °C and demonstrates high resistance to both UV and X-ray radiation at elevated doses. This work provides an innovative solution for self-healing materials designed for harsh environments.

The highly selective semi-hydrogenation of acetylene in ethylene-rich streams is essential for polyethylene production. However, environmentally friendly non-precious metal catalysts are often limited by the difficulty of balancing activity and selectivity. This study employed a facile in-situ pyrolysis strategy of MOFs to successfully prepare a Ni/ [email protected] heterojunction catalyst. This catalyst exhibited outstanding performance in acetylene semi-hydrogenation, achieving an acetylene conversion of 96.16 % and ethylene selectivity of 87.22 %. Mechanistic studies revealed that its superior performance originates from highly dispersed H 2 activation sites and a unique interfacial synergistic effect. On the one hand, the strong interfacial interaction formed between Ni and ZnO not only significantly enhances the dispersion and air stability of the active Ni 0 species but also effectively promotes the activation and dissociation of H 2 molecules. On the other hand, the electron reconstruction induced by the Ni/ZnO interface significantly reduces the energy barrier of the rate-determining step promotes the rapid desorbed of the product ethylene, and inhibits excessive hydrogenation. This work provides a novel heterojunction engineering strategy for designing highly efficient, stable, and sustainable non-noble metal selective hydrogenation catalysts.

The inadequacy of current antithrombotic therapies lies in the limited efficacy of pharmacotherapy and the poor targetability of drugs to thrombotic sites. To address these challenges, we developed a multifunctional nanoplatform, Fe 3 O 4 @MC-DEA-PBAP (FMDP), which integrates magnetic responsiveness and erythrocyte targeting for magnetic hyperthermia thrombolysis (MHT). FMDP is constructed using metal–organic frameworks (MOFs) crosslinking CaCO 3 /cyclodextrin as the base carrier, modified with 2-(Diethylamino)ethyl methacrylate (DEA) and 4-hydroxyphenylboronic acid pinacol ester (PBAP), then conjugated with nano-ferric oxide for MHT. DEA and PBAP make FMDP to adhere onto erythrocytes and scavenge reactive oxygen species (ROS), respectively. In vitro experiments proved that FMDP exhibits high photothermal conversion efficiency and robust magnetic responsiveness, enabling the thrombolytic efficiency of FMDP was three times that of uPA group. In addition, FMDP adhere to erythrocytes (83.5 %) and reach the thrombi under the cover of erythrocytes for MHT. In addition, FMDP effectively scavenges ROS, mitigating endothelial damages and promoting vascular regeneration. Overall, FMDP represents a promising therapeutic strategy for the comprehensive management of thrombosis, offering improved efficacy and reduced bleeding risks compared to conventional thrombolytic therapies.

A simple method for fabricating a metal organic framework (MOF: HKUST-1) as sorbent for selective removal of chromium (III) from aqueous solution is discussed. The structure and morphology of HKUST-1 was identified by fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), the powder X-ray diffraction (XRD) and N2 adsorption-desorption (BET) analysis. Its removal process of chromium (III) and chromium (VI) on HKUST-1 was assessed systematically under various conditions such as pH value, shaking time and initial concentration of chromium (III). At pH 6.0–8.0, HKUST-1 were selective towards chromium (III) but hardly chromium (VI). Kinetic parameters fitted well with pseudo-second-order model and adsorption progress was described by Langmuir isotherm equations and spontaneous and endothermic according to the results of thermodynamics studies (▵G < 0, ▵H > 0, ▵S > 0).

In this work, a high-sensitivity electrochemical sensor was developed using a hybrid strategy, where sheet-like MXenes-based composites (Bi-MOF/MXenes) were prepared through the in-situ growth of bismuth-based metal-organic frameworks (Bi-MOF) on the MXenes surface. This hybrid composite material was fabricated using a simple physical synthesis method, which maintains excellent electrocatalytic activity while enhancing the electron transfer rate and electroactive surface area. The Bi-MOF/MXenes modified electrode has been demonstrated to be an effective tool for the detection of nitrite. The electrode exhibited a remarkable limit of detection (LOD) of 0.028 μM and a wide linear range of 0.5~4715 μM. The sensor exhibited remarkable repeatability and reproducibility, with relative standard deviation (RSD) values of 1.74% and 4.87%, respectively. The proposed approach was effectively utilized for detecting nitrite in sausage and fermented bean curd.

To develop a low-carbon and highly efficient alternative to the energy-intensive Haber-Bosch process for ammonia synthesis, this study designed a Zr, Fe bimetallic organic framework (ZrFe-MOF) using 1,4-Benzenedioic acid (H 2 BDC) as the organic ligand and Zr 4+ /Fe 3+ as dual metal centers via a hydrothermal synthesis method. The resulting material was systematically investigated for its performance in photocatalytic and piezoelectric (under ultrasonic conditions) synergistic nitrogen reduction reaction (PPNRR).The synergistic coordination of trivalent and tetravalent metal ions engenders an augmented density of coordination defects and active sites within the material framework. Structural characterization confirmed that Fe species were uniformly dispersed within the Zr-BDC matrix, forming a stable coordination structure . The optimal ZrFeBDC-55 exhibited distinct piezoelectric properties and achieved an ammonia production rate of 7026.85 μmol·L −1 ·h −1 ·g −1 , under the synergistic effect of light and ultrasound, significantly outperforming monometallic Zr-BDC and Fe-BDC, respectively. Mechanistic analysis revealed that the bimetallic synergy introduced sub-bandgap energy levels that effectively suppressed recombination of photogenerated electron-hole pairs, while the more negative conduction band potential enhanced the catalyst’s reduction capability. Furthermore, the piezoelectric effect promoted efficient charge carrier separation and migration under ultrasonic conditions. The catalyst demonstrated excellent recyclability, maintaining both structural integrity and catalytic activity over four cycles. Notably, irrigation of rice seedlings with the synthesized ammonia solution resulted in a 32% increase in plant height and optimized root development, verifying agricultural application potential. This work presents a novel strategy for high-performance photopiezoelectric catalysts for nitrogen reduction and lays a foundation for low-carbon agricultural nitrogen supply technologies.

Efficient detection of heavy metal ions in complex marine environments is essential to the safety of marine organisms and human beings. This study developed a novel screen-printed-electrode (SPE) electrochemical sensor for rapid on-site determination of typical heavy metal ions such as Cu2+, Pb2+, Cd2+, and Hg2+in seawater. The sensor employs a three-electrode system, with the working electrode modified with a composite of metal–organic framework-derived carbon (MOF-C) and multiwalled carbon nanotubes (MWCNTs), thereby significantly enhancing detection sensitivity and selectivity. By optimizing square-wave anodic stripping voltammetry (SWASV) parameters, detection limits of 0.83, 0.40, 1.05, and 0.30 μM for the detection of Cu2+, Pb2+, Cd2+, and Hg2+ions were achieved. In mixed-ion detection, excellent peak separation and strong resistance to interferences were demonstrated. Experimental results demonstrate that the sensor exhibits good linear response, excellent interference resistance, and high practicality, providing a new approach for rapid on-site determination of heavy metal pollution in marine environments.

Light-responsive proton conductors represent an attractive research direction owing to their potential in intelligent devices and responsive sensing applications. Herein, we present a cooperative functionalization strategy to construct an MOF-based light-regulated proton-conducting material, MOF-808-AZOA-IL, by integrating azobenzene-4,4′-dicarboxylic acid (AZOA) and an ionic liquid (IL) into the MOF-808 framework. AZOA serves as a photoactive unit to endow light responsiveness, while the IL molecules form a continuous proton-conducting network, enhancing the concentration and mobility of protons. This synergy results in a proton-conduction on/off ratio up to ∼2000 of MOF-808-AZOA-IL, with excellent stability over repeated UV light on/off cycles. This work demonstrates that the incorporation of AZOA and IL synergistically enhances the light-regulated proton conduction of MOF-808, offering a reliable strategy for designing advanced stimuli-responsive proton-conductive systems.

Solar-driven atmospheric water harvesting (SAWH) holds significant promise for decentralized water supply. However, its widespread application is hindered by two critical limitations: underutilization of high-humidity adsorption windows during nighttime and insufficient desorption during daytime due to the high desorption temperature requirement of conventional sorbents. To overcome these challenges, this study proposes a composite sorbent strategy by synergistically combining the low enthalpy of vaporization of LiCl with the robust adsorption capacity and stability of a metal‒organic framework (MOF, specifically Ni 2 Cl 2 (BTDD), H 2 BTDD = bis(1 H −1,2,3-triazolo[4,5- b ],[4′,5′- i ])dibenzo[1,4]dioxin). This design leverages the complementary properties to achieve lower desorption temperatures ( e.g ., < 60 o C in device level) compared to typical MOF-based systems (usually >90 o C in device level), thereby significantly reducing the energy consumption for desorption. Concurrently, the composite exhibits extended adsorption duration within the high-humidity window. Field validation across diverse climatic regions demonstrates the composite’s exceptional wide-range environmental stability and performance. The resulting SAWH device achieves a solar-to-water generation improvement up to 91% in a continental field test. This work presents a generalizable and effective pathway for enhancing SAWH performance through synergistic material engineering, enabling efficient water production and thermal control under varying environmental conditions.

Exploring CO 2 adsorption under humid conditions is crucial for practical applications. Herein, ZJU-521(Al) was synthesized using low-toxicity helical secondary building units (SBUs, [Al 5 (OH) 7 (−COO) 8 ] ∞ ) and tetrakis (4-carboxyphenyl)methane (H 4 MTTB) ligand, with excellent chemical stability. Saturated CO 2 adsorption capacities of ZJU-521(Al) reach 6.19 mmol/g at 273 K and 4.52 mmol/g at 298 K, respectively, and moderate isosteric heat of 28.23 kJ/mol, enabling low-energy regeneration. Simulation results reveal two CO 2 adsorption sites on ZJU-521(Al): site I, located near the helical SBUs and interwoven with the helical SBUs, and site II, situated near the H 4 MTTB ligand. ZJU-521(Al) can effectively separate CO 2 from the CO 2 /N 2 mixture, as identified by the ideal adsorbed solution theory values of 28.81 at 273 K and 40.83 at 298 K for CO 2 /N 2 (15/85) mixture, respectively. Dynamic adsorption experiments reveal dynamic CO 2 adsorption of 0.59 mmol/g under dry conditions and 0.54 mmol/g at 80% relative humidity (RH) for ZJU-521(Al), highlighting its moisture-resistant behavior for CO 2 adsorption under humid conditions. Most adsorbed CO 2 is readily desorbed by argon purging at 14 min (dry) and 12 min (80% RH) at 298 K, respectively. Therefore, ZJU-521(Al) emerges as a promising candidate for efficient CO 2 adsorption, separation, and desorption even under humid conditions.
