The dual-signal output self-calibration mode reduces the false positive and negative signals of electrochemiluminescence (ECL) aptamer sensors. A competitive dual-signal ECL platform was designed for the ultrasensitive detection of kanamycin (KAN) using a zirconium metal–organic framework (Zr MOF) and Luminol as ECL emitters. To enhance the ECL efficiency, a co-reactant (polyethyleneimine, PEI) was covalently bound to the Zr MOF to achieve self-enhanced ECL. Based on the selective interaction between KAN and its aptamer, the Luminol/KAN/Zr MOF-PEI “sandwich” structure was immobilized on the electrode surface. The competition for PEI between emitters increased the Luminol ECL signal and decreased the Zr MOF’s ECL signal. The ratio in ECL signals between the two competitive emitters enabled the quantitative analysis of KAN, achieving a detection limit as low as 7.86 × 10−4ng/mL. This study elucidated the synergistic mechanism between self-enhanced ECL and ECL competition, offering a novel approach for constructing dual-signal ECL sensors using a single co-reactant.

The research of metal organic frameworks materials of possessing semiconductor performance is important because they show great prospects on applications in wastewater treatment . In the current work, composites of TiO 2 / MOF-801(Zr) was prepared by a wet impregnation at room temperature , and a series of characterizations for catalysts, such as XRD , TEM , XPS, etc was investigated. The results of photocatalytic reduction of Cr(Ⅵ) under simulated solar light irradiation showed that 50%TiO 2 / MOF-801(Zr) exhibited better photocatalytic activity compared with other catalysts, which is attributed to synergistic effect including the interface enhancement effect and the enhancement of photogenerated carriers separation efficiency. The photocatalytic efficiency is as high as 98.1% when adjusting pH of reaction system to 1. It is most likely because the hydrogen cation concentration increased along with the increasing acidity, so that as to the promoting of reduction process of Cr(Ⅵ). In addition, we proposed a possible reaction mechanism of TiO 2 / MOF-801(Zr) composites for photocatalytic reduction of Cr(Ⅵ).

Nanoscale Zr-based metal-organic framework (MIP-202) particles were successfully prepared via a seeds-assisted hydrothermal secondary synthesis. The uniformly-shaped MIP-202 particles exhibit excellent performance on selective CO 2 adsorption from CO 2 /CH 4 and CO 2 /N 2 mixtures. At 298 K and 1 bar, the uptake ratios of CO 2 /CH 4 and CO 2 /N 2 of MIP-202 particles are as high as 32.6 and 65.2, respectively. The IAST (ideal adsorbed solution theory)-predicted selectivities of CO 2 /N 2 (50/50, v/v) and CO 2 /CH 4 (50/50, v/v) reach to 4.5 × 10 10 and 102.2, respectively. The breakthrough experiments further demonstrate that the CO 2 /CH 4 and CO 2 /N 2 mixtures can be efficiently separated through an adsorption column packed with MIP-202 particles. In addition, the as-prepared MIP-202 particles had a low iso-enthalpy of adsorption of CO 2 of 32.95 kJ/mol, which is favorable for the regeneration of the adsorbent. Herein the as-prepared MIP-202 is a potential material for efficient separation of CO 2 from CH 4 or N 2 through an energy- and cost-saving CO 2 capture process.

Achieving a stable interface between sulfide solid-state electrolytes (SSEs) and high-voltage Ni-rich oxide cathodes is crucial for enhancing the electrochemical performance of all-solid-state batteries (ASSBs). However, addressing the interface challenges through surface coating modifications remains a significant hurdle. In this work, a straightforward modification approach is proposed to achieve a highly stable interface by surface dual doping of Zr and F in LiNi 0.83 Co 0.12 Mn 0.05 O 2 (NCM83) cathodes via acid washing followed by annealing. First-principle calculations demonstrate the thermodynamic stability of Zr-F doped NCM83, effectively inhibiting the formation of unfavorable interfaces with decomposition products. The modified NCM83-1% ZrF cathode exhibits exceptional long-cycle stability, retaining 85.1% of its capacity after 1000 cycles at 0.5C rate. This simple and scalable modification strategy offers a new perspective for the design of high-performance sulfide-based ASSBs.

The Zr-based chloride solid electrolyte (SE) Li2ZrCl6 is well compatible with 4 V-class cathodes and cost-effective, yet its low conductivity (<1 mS cm−1) would restrain the capacity delivery of the electrodes especially at high rates. Herein, we further elevated the room-temperature ionic conductivity of Zr-based lithium oxychloride to 2.11 mS cm−1 in Li2.15Zr0.85In0.15Cl4O by tuning its Li content through partial substitution of Zr4+ with In3+ in the formula Li2+xZr1−xInxCl4O. Cold-pressed Li2.15Zr0.85In0.15Cl4O presents both a dense morphology arising from its amorphous phase and enhanced ionic conductivity, which is significantly higher than that of Li2ZrCl6, facilitating better solid–solid contact and improved reaction kinetics in the composite cathodes. As a result, the all-solid-state cathode coupling Li2.15Zr0.85In0.15Cl4O and LiNi0.92Co0.03Mn0.05O2 shows a capacity of 175.3 mAh g−1 at 4C and a retention of 91.44% for 450 cycles when charged to 4.3 V vs. Li+/Li. More attractively, as the charge upper limit increases to 4.8 V, Li2.15Zr0.85In0.15Cl4O also enables ultrahigh-nickel cathodes to cycle for over 250 cycles with a capacity retention of 81.86%.

Construction of highly efficient catalysts is crucial for the catalytic transfer hydrogenation (CTH) of bio-based carbonyls to valuable chemicals and fuels. Herein, we successfully synthesized a series of uniformly dispersed Zr(OH) 4 -Fe 3 O 4 nanoparticles with the regulation of sodium dodecyl benzene sulfonate (SDBS), which exhibited exceptional activity for the CTH of furfural (FAL) into furfuryl alcohol (FOL). Systematic characterizations revealed that SDBS effectively modified the interaction between Fe 3 O 4 and Zr(OH) 4 , thereby enhancing Lewis acidity by facilitating the construction of electron-deficient zirconium sites. Meanwhile, the presence of oxygen vacancies and surface hydroxyl groups in Zr(OH) 4 -Fe 3 O 4 -SDBS facilitated the adsorption and activation of both substrate and hydrogen donor. Thanks to these synergistic effects, a complete conversion of FAL with an impressive selectivity towards FOL was achieved, with a remarkable turn-over frequency value reaching as high as 42.5 h −1 . Encouragingly, Zr(OH) 4 -Fe 3 O 4 -SDBS also demonstrated its universality in the CTH of carbonyl compounds by exhibiting remarkable separation capability while maintaining its activity and structure after being reused for 11 cycles without significant changes.

The present study investigates the efficacy of newly developed Zr-based metal–organic frameworks, specifically MIP-206, and its amine-modified counterpart, MIP-206-NH 2 , for the re-covery of antimony (Sb) from both synthetic and actual mining wastewater. Batch method studies were employed to examine the effect of waste media pH, Sb concentration, process kinetics, and the performance of the regeneration solution. MIP-206-NH 2 exhibited impressive separation capabilities, achieving 102.18 mg/g and 63.23 mg/g for Sb (V) and Sb (III), respectively. In contrast, the pristine MIP-206 reached maximum values of 26.26 mg/g for Sb (V) and 16.95 mg/g for Sb (III). The separation process was well-described by the Langmuir equation, and the kinetics followed the pseudo-second-order model. Although the amine modification resulted in a decrease in the surface area of MIP-206 from 1345.21 to 1169.86 m 2 /g, SEM and XRD analyses confirmed that the structural integrity of MIP-206-NH 2 remained unchanged. In terms of reusability, MIP-206-NH 2 maintained up to 90% of its separation performance over 9 cycles, while MIP-206 demonstrated effectiveness for 7 cycles. The regeneration solution exhibited a capacity of approximately 0.63 mol/L for Sb (V) and 0.71 mol/L for Sb (III). Furthermore, MIP-206 and MIP-206-NH 2 demonstrated successful application in selectively separating Sb from real mining wastewater.

Designing highly conductive and (electro)chemically stable inorganic solid electrolytes (SEs) from cost-effective precursors is critical for developing all-solid-state batteries (ASSBs). Herein, we report a series of low-cost zirconium (Zr) -based halide nanocomposite SEs, Li1+2xZr1–xTaxO3xCl5–3x (x = 0.33, 0.4, 0.5), synthesized via mechanochemical interaction between LiTaO3 and ZrCl4. The optimized composition, Li1.8Zr0.6Ta0.4O1.2Cl3.8, exhibits enhanced ionic conductivity from 0.46 to 1.12 mS cm–1 and decreased electronic conductivity. Mechanochemical processing modulates the local structural environments of the halide nanocomposites, facilitating ion transport. Combined characterization, including X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy, and synchrotron X-ray absorption spectroscopy, reveals that oxygen-substituted nanocomposites with distorted local structures are key to improving ion transport. Finally, we demonstrate ASSBs using Li1.8Zr0.6Ta0.4O1.2Cl3.8 as the SE, single-crystalline LiNi0.8Co0.1Mn0.1O2 (scNCM811) as the cathode, and Li–In alloy as the anode, achieving stable cycling at room temperature and 1 C rate.

Oral squamous cell carcinoma (OSCC) is the most common malignant tumor in the head and neck. Due to low bioavailability and passive targetability of anticancer drugs show great limitations in cancer therapy, the treatment of OSCC faces major challenges. Folic acid (FA) targeting can deliver anticancer drugs efficiently into the tumor environment, further enhance the anti-cancer efficacy. Herein, the nanoplatform based on UiO-66 that encapsulated with an effective FA targeting ligands and the pH-responsive polyethylene glycol (PEG) layer for the targeted delivery of berberine (Ber) is constructed for fighting against OSCC. The FA modification and controlled pH-responsiveness enable the targeted delivery of UiO-66/PEG-FA, which promotes the release of Ber and increases the cumulative intracellular Ber concentration, which both promote consumption of glutathione (GSH) and induced generation of reactive oxygen species (ROS), further stimulate the secretion of inflammatory factors (TNF-α and IL-1β). A comprehensive evaluation of in vitro and in vivo experiments show that UiO-66@Ber/PEG-FA promote autophagy and apoptosis of tumor cells by regulating the expression of Beclin-1, ATG13, BAX and Bcl-2, and effectively inhibit tumor growth. Overall, UiO-66@Ber/PEG-FA exhibit superior pH-responsiveness and targeted therapeutic efficiencies in vitro and vivo, it can serve as an approach for OSCC therapy.

The pursuit of high-energy-density all-solid-state lithium batteries necessitates integration with next-generation high-voltage positive electrodes. However, a critical challenge lies in the intrinsic instability of most highly ionically conductive solid electrolytes, which decompose at potentials above 4.30 V vs Li + /Li, resulting in severe interfacial degradation and increased impedance. Here, we show that an amorphous Li 2 Zr 0.625 Ta 0.3 Cl 4.2 O 0.9 halide electrolyte, synthesized via a non-equimolar cation-anion amorphous engineering strategy based on Li 2 ZrCl 6 , effectively overcomes this limitation. With a high ionic conductivity of 4.11 mS cm −1 at 25 °C, it enables stable high-potential cycling through kinetically stabilized operation mediated by a self-passivating positive electrode–electrolyte interphase. When paired with LiNi 0.88 Mn 0.06 Co 0.06 O 2 positive electrode and a Li-In alloy negative electrode, the cells retain up to 81.2% of the initial capacity after 2,000 cycles at 10 C under cell cutoff voltages of 4.18 V (corresponding to 4.80 V vs Li⁺/Li). Overall, non-equimolar cation–anion amorphous engineering enables conductive, high-voltage-tolerant Zr-based halides for all-solid-state lithium batteries.

A sensitive and accurate ratiometric fluorescent sensor (RhB@UIO-67) is constructed by simply encapsulating rhodamine B (RhB) within a zirconium-based metal–organic framework (UIO-67). Based on the inhibition effect of ligand–to-metal charge transfer, adenosine triphosphate ATP induces a significant enhancement in the MOF centre emission, but does not affect the fluorescence of RhB in the probe material at all, which are respectively employed as detection signal and reference signal to realize sensitive ratiometric fluorescence detection of ATP in human serum and urine with a detection limit (LOD) of 0.45 μM. In particular, since the introduction of the target molecules does not cause any structural degradation, the sensor can be reused. Additionally, due to fluorescence resonance energy transfer between the probe components and malachite green (MG), addition of MG results in different degrees of quenching of the fluorescence emissions of UIO-67 and RhB in the RhB@UIO-67 and thus the probe material can simultaneously serve as a sensitive ratiometric sensing platform for MG detection in aquatic products including fish and shrimp with a low LOD of 0.03 μM. Benefited from its simplicity, sensitivity, and reusability, the sensing material has a wide application potential. Graphical abstract

The existence of highly effective antibacterial agents such as triclosan (TCS) in terrestrial environments and even the human body results in increasing ecological and public health risk due to their potential toxicity. Here, a series of magnetic porous carbon spheres derived from Zr/Fe-based bimetallic organic framework, denoted as Zr/Fe-MOF@C, were developed for the efficient removal of triclosan (TCS) from water. The Zr/Fe-MOF@C demonstrated enhanced adsorption performance for TCS with a maximum adsorption capacity of 769.23 mg/g in 30 s. This value is ~10 times higher than that of many previously reported materials, demonstrating a significant advancement. The adsorption isotherms and kinetics of TCS on Zr/Fe-MOF@C were best described by the Langmuir and pseudo-second-order models, respectively. The thermodynamic analysis confirmed that the TCS removal process was favorable, spontaneous, and exothermic. Notably, Zr/Fe-MOF exhibited exceptional regenerative stability, retaining adsorption capacity of 308–410 mg/g over four consecutive adsorption–desorption cycles. The removal mechanism of TCS by Zr/Fe-MOF@C is primarily attributed to the synergistic effects of π-π stacking interaction, hydrophobic interaction, and pore filling effects. Given its rapid adsorption kinetics, excellent removal capacity, and convenient recyclability via external magnets, Zr/Fe-MOF@C emerges as a promising adsorbent for TCS removal from surface water, highlighting its strong potential for practical applications in real-water treatment.
