In this study, attapulgite (ATP) was modified by Zr-based metal organic framework (UiO-66-NH 2 ) and poly(hexamethylenediamine-tannic acid) (HTA), an amino material named UiO-66-NH 2 /HTA/ATP (UHA) was prepared to efficiently remove Cr(VI). The morphology and structure of UHA were analyzed through various characterization methods. The conditions and influencing factors of UHA preparation and Cr(VI) adsorption were studied. The material had a maximum adsorption capacity of 270.3 mg/g for Cr(VI) when pH was 2.0, temperature was 298 K, adsorption time was 300 min, and ionic strength was 0.01 mol/L, which was obtained by the Langmuir fitting model. The adsorption process conforms to the pseudo-second-order kinetic and Langmuir isothermal models, indicating that the adsorption process is mainly based on the chemical adsorption of monolayers. X-ray photoelectron spectroscopy analysis shows that UHA mainly removes Cr(VI) by hydrogen bonding , electrostatic attraction, reduction, and complexation. Thermodynamic investigation suggested a disordered, endothermic and spontaneous adsorption process. After UHA treatment, the simulated wastewater containing Cr(VI) met the discharge standard, and the results of cycling experiments showed that UHA has good renewable performance and offers potential prospects for Cr(VI) removal in water.

Excessive discharge of uranyl ion (U(VI)-containing) wastewater poses significant environmental and human health risks due to radiological contamination. In this study, a metal–organic framework (MOF) exhibiting aerogel-like properties was synthesized by combining UiO-66-NH 2 with MXene through a freeze-drying process. The research focused on the removal of U(VI) from aqueous solutions with this aerogel material. The adsorption isotherm was consistent with the Langmuir model, and the maximum adsorption capacity was determined to be 229.1 mg∙g −1 . The aerogel-like MOF possesses a mesoporous structure, enhancing its U(VI) adsorption efficiency while enabling easy separation and maintaining structural integrity afterward. In cyclic adsorption–desorption experiments conducted over five cycles, the UiO-66-NH 2 /MXene adsorbent demonstrated a U(VI) removal efficiency exceeding 96 %. Overall, the aerogel-like MOF demonstrates outstanding U(VI) adsorption capacity and shows promise as an effective capacitive deionization (CDI) electrode for mitigating radiological contamination.

Herein, we report a novel UiO-67-Co(bpy)0.35 micromotor synthesized by a facile postsynthesis metalation via introducing cobalt salts ligated with 2,2′-bipyridine-5,5′dicarboxylic acid into UiO-67-bpy0.35 framework. The Co2+ active sites can decompose H2O2 to generate bubbles to power UiO-67-Co(bpy)0.35. Meanwhile, the UiO-67-Co(bpy)0.35 micromotor exhibits robust peroxidase-like activity through catalyzing H2O2 to generate •OH under neutral conditions. Based on this, a sensing platform was constructed for the colorimetric detection of GSH. Due to the synergy of self-driven motion and excellent peroxide-like activity, UiO-67-Co(bpy)0.35 micromotor can sensitively detect GSH with a low analytic limitation as 0.13 μM for GSH detection. This study provides a new sight of using the postsynthesis metalation method to prepare Zr(Co)-MOF micromotor for highly selective, sensitive, and facile detection of GSH.

The high stability and other properties of Zr(IV)-based metal organic frameworks(MOFs) make it a promising choice for chromatographic separation, while the application in open-tubular capillary electrochromatography (OT-CEC) separation has not been explored yet. Herein, we report the first example of the in-situ growth of UiO-66-NH 2 onto the capillary for open-tubular capillary electrochromatography. UiO-66-NH 2 consists of ZrCl 4 and 2-amino-1,4-benzenedicarboxylic acid, which is highly porous and stable in a variety of solvents. The prepared UiO-66-NH 2 modified capillary was characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectra (FT-IR), and the results confirmed the successful growth of the UiO-66-NH 2 . The baseline separation of chlorobenzenes, phenoxyacids and two groups of phenols was achieved owing to the combined interaction of π-π interaction, hydrophobic interaction, molecular sieve effect, electrophoretic migration and hydrogen-bonding interaction etc. Besides, the prepared capillaries showed good reproducibility, with relative standard deviations (RSDs) for intra-day, inter-day and column-to-column runs in the range of 1.38–2.60%, 3.39–4.05%, and 3.47–5.03%, respectively. Our work indicates Zr(IV)-based MOFs are promising materials as stationary phase in CEC separation.

Microplastics are a worldwide problem that poses a giant threat to organisms in the ecosystem and even to human health. The removal of microplastics is a severe challenge that needs to be solved urgently. Herein, a series of zirconium metal–organic framework-based foam materials with interpenetrated pores, high MOF uniformity and excellent durability have been successfully fabricated and applied in simulated microplastics removal in water or seawater conditions. They can be applied to various types and concentrations of microplastics suspensions. It is worth noting that the best of them, UiO-66-OH@MF-3, can efficiently remove microplastics with an efficiency of up to 95.5 ± 1.2% and can maintain high performance in recycling and large-quantity filtration experiments. Besides, we proposed an automatic filtration system powered by sunlight and accomplished it on the lab-scale. The high performances of these foam materials combined with the new concept of automatic filtration systems might shed some light on the development of novel techniques for microplastics removal.

Comprised of a battery anode and a supercapacitor cathode, hybrid lithium-ion capacitors (HLICs) are found to be an effective solution to realize both high power density and high energy density at the same time. Organic–inorganic hybrid materials with well-organized framework guided by the reticular chemistry are one of the promising anode materials for HLICs because of rich active sites and ordered porosity. Herein, metal−organic framework consisting of Zr 4+ metal ions and tetrathiafulvalene-based ligands (Zr-MOF) is proposed as the pseudocapacitive anode of HLICs. The Zr-MOF possesses high stability, high crystallinity, and multiple meso-microporous channels favorable for ion transport. The as-prepared Zr-MOF||activated carbon HLICs present high energy density (122.5 Wh kg −1 ), high power density (12.5 kW kg −1 ), and stable cycling performance (86% capacity retention after 1000 cycles at 2000 mA g −1 ) within the operating voltage range of 1.0–4.0 V. The results expand the direct application of MOF for bridging the performance gap between batteries and supercapacitors.

The adsorptive removal of tetracycline (TC) was studied with three types of zirconium-based metal–organic frameworks (Zr-MOFs), UiO-66, NU-1000 and MOF-525. The adsorption kinetics best fitted with the pseudo-second-order kinetic model and the adsorption equilibrium was rapidly reached within 40 min on UiO-66 and NU-1000, and 120 min on MOF-525. The adsorption isotherms best fitted with Sips model, and the maximum Sips adsorption capacities of TC on UiO-66, NU-1000 and MOF-525 were 145 mg·g −1 , 356 mg·g −1 and 807 mg·g −1 respectively, which were much higher than common adsorbents. The X-ray photoelectron spectra measurements and the influence of pH suggested that the π-π interaction played a crucial role during the adsorption. Pore characteristics and topology of MOFs showed great effect on adsorption performance. The cages whose size match well with TC helped MOF-525 to get highest adsorption amount per surface area among MOFs we studied. The proper topology of NU-1000 contributed to its high adsorption rate. River water was also used to confirm the excellent adsorptive performance of these three Zr-MOFs in practical application. These results might aid us to comprehend the adsorption of TC on Zr-MOFs and expand the application of Zr-MOFs in water treatment for removal of emerging contaminants.

Eutrophication of water bodies caused by the excessive phosphate discharge has constituted a serious threat on a global scale. It is imperative to exploit new advanced materials featuring abundant binding sites and high affinity to achieve highly efficient and specific capture of phosphate from polluted waters. Herein, water stable Zr-based metal organic frameworks (MOFs, UiO-66) with rational structural design and size modulation have been successfully synthesized based on a simple solvothermal method for effective phosphate remediation. Impressively, the size of the resulting UiO-66 particles can be effectively adjusted by simply altering reaction time and the amount of acetic acid with the purpose of understanding the crucial effect of structural design on the phosphate capture performance. Representatively, UiO-66 particles with small size demonstrates 415 mg/g of phosphate uptake capacity, outperforming most of the previously reported phosphate adsorbents. Meanwhile, the developed absorbents can rapidly reduce highly concentrated phosphate to below the permitted level in drinking water within a few minutes. More significantly, the current absorbents display remarkable phosphate sorption selectivity against the common interfering ions, which can be attributed to strong affinity between Zr–OH groups in UiO-66 and phosphate species. Furthermore, the spent UiO-66 particles can be readily regenerated and reused for multiple sorption–desorption cycles without obvious decrease in removal performance, rendering them promising sustainable materials. Hence, the developed UiO-66 adsorbents hold significant prospects for phosphate sequestration to mitigate the increasingly eutrophic problems.

This study constructed boronic acid grafted Zr-MOF (BA-Zr-MOF) by a simple pre-installation strategy through mixed organic ligands. Typically, BA-Zr-MOF was prepared by one-step hydrothermal method used for enrichment of cis -diol-containing nucleosides through pipette tip solid-phase extraction (PT-SPE) followed by detection of high-performance liquid chromatography. It is worth mentioning that BA is well assembled into MOF and cis -diol-containing compounds can be efficiently and selectively enriched by abundant boronic acid groups. Three groups of different types of compounds were used to evaluate their selectivity and the results showed the excellent selectivity to cis -diol-containing compounds of as-prepared adsorbent. The BA-Zr-MOF adsorbent possesses a high adsorption capacity, which can reach 86.40 mg g −1 for adenosine. Under the optimal extraction condition, a PT-SPE-HPLC method based on BA-Zr-MOF for analysis of nucleosides was established. The linear range of the four nucleosides is 0.01 to 50 µg mL −1 with R 2 ≥ 0.99 and the detection limits (LODs) are estimated at between 0.005-0.012 µg mL −1 . The recoveries in urine were used to test the reliability of the analytical methods, which ranged from 82.8% to 117.1%, with intra-day relative standard deviations (RSDs) ranged from 0.1% to 4.2% and the inter-day RSDs ranged from 0.2% to 6.2%. All the results show that the pre-installation strategy based on dual ligands is an alternative to fabricate MOF composite material and BA-Zr-MOF is a promising material for the analysis of cis -diol-containing biomolecules.

Developing reliable sensors that accurately detect deadly chemical gases is critical to global security. Nerve agents are one of the most dangerous chemicals in the world and are often found in gaseous forms in the environment, which remain a challenge to detect because of their low levels. In this paper, a fluorescent probe based on a Zr-based metal–organic framework UiO-66–NH2 was proposed. The specific binding between the Zr–O site of UiO-66–NH2 and diethyl chlorophosphate (DCP) blocked the ligand-to-metal charge transfer (LMCT) process in UiO-66–NH2, thereby enabling the fluorescence turn-on detection of DCP. More importantly, a simple and portable hydrogel soft-solid platform (UiO-66–NH2@Aga) was constructed by incorporating UiO-66–NH2 into the formation process of agarose (Aga) hydrogel for fast and sensitive detection of gaseous DCP. When the hydrogel was exposed to a low concentration of DCP vapor, its fluorescence changed from colorless to bright blue, allowing visualization of the DCP gas for analysis. The UiO-66–NH2@Aga integrated solid-state platform showed an excellent response to DCP vapor in the detection range of 1.98 to 9.90 ppm and with a detection limit of 1.16 ppm. This work opened up a unique way to design a convenient, low cost and practical gas physical examination platform.

The HILIC enrichment is a greatly compatible strategy for the extraction of glycopeptides in proteomics. Herein, a boric acid and fructose-1,6-diphosphate (FDP) dual-functionalized Zr-based metal–organic framework material UIO-PBA&FDP (UIO is the abbreviation for the University of Oslo, and PBA is the abbreviation for carboxy phenylboronic acid) was synthesized, characterized with the desirable excellent hydrophilicity and thus was explored for the enrichment of N-linked glycopeptides utilizing the HILIC interaction between the glycopeptides and the hydrophilic UIO-PBA&FDP at a high level of ACN concentration. A total of 359 N-linked glycopeptides corresponding to 104 glycoproteins were identified from only 1 μL of digested human serum by the enrichment of UIO-PBA&FDP, which showed a superiorly high coverage of the identified glycopeptides. The dual hydrophilic functionalized UIO-PBA&FDP could be an efficient HILIC material for the enrichment of N-linked glycopeptides from complex biological samples.

Deep desulphurization of diesel is essential because the sulfides from fuel combustion can cause acid rain, respiratory diseases and corrosion of industrial equipment. Peroxophosphomolybdate (BTA) 3 {PO 4 [MoO(O 2 ) 2 ] 4 }·3H 2 O, marked as PMo 4 , was confined in size-matched Zr-MOFs (UiO-66 and UiO-67) to prepared composites for extractive oxidative desulfurization. The composites underwent comprehensive characterization, including ICP-MS, FT-IR, XRD, SEM, XPS, TG and N 2 adsorption–desorption analysis. Desulfurization test was conducted with PMo 4 as homogeneous catalyst, and the reaction conditions were optimized. Then, the catalytic activity of the prepared composites was compared, and the result showed that the catalyst PMo 4 @UiO-67 can remove 94.1 % of the sulfides in the diesel within 100 min. After 15 consecutive tests, the total removal rate of sulfides still reached 88.5 %, thanks to the narrow window of carrier UiO-67 limited the leaching of the active component PMo 4 .
