Herein, phosphorylated MOF@COF (UiO-66-NH 2 @HDU-27-P) Type-II heterostructures were constructed to achieve selective and efficient uranium extraction. These composites were synthesized via the covalent linking of MOFs with COFs at varying ratios, and their electronic properties were analyzed using density functional theory (DFT) calculations. The optimized 6:1 composite exhibited exceptional performance, achieving (> 92.9 %) U(VI) removal in pure water and maintaining high efficiency across complex aqueous environments, including seawater. Mechanistic studies revealed that the Type-II heterojunction significantly enhances charge separation, enabling uranium capture through synergistic adsorption, photocatalytic reduction, and immobilization under non-sacrificial air conditions. This work provides a new paradigm for designing high-performance heterojunctions, offering a superior alternative to current materials for sustainable environmental remediation and uranium recovery.

The innovation for highly effective solid acid catalysts that resist impurities is crucial for enhancing sustainable esterification and transesterification processes, which are vital for biofuel production and green chemistry. In this work, tungsten-modified sulfated titania (WO₃/SO₄ 2 ⁻/TiO₂) catalyst was prepared through the impregnation method and subsequently calcined at 550 °C to assess the impact of tungsten impurity on its structural and catalytic properties. The catalyst was characterized through FT-IR, XRD, NH 3 -TPD, and BET surface area analysis. These analyses revealed that the presence of sulfate and tungsten species inhibited TiO₂ crystallization, improving the textural properties and increasing surface acidity. The 5 wt.% WO₃/SO₄ 2 ⁻/TiO₂ catalyst demonstrated the largest surface area (35.99 m 2 /g) and total acidity (1.20 mmol NH₃/g). This catalyst achieved 86.4% conversion in the reaction of transesterification of ethyl acetate and n-butanol at 100 °C for 3 h. The enhanced catalytic performance and selectivity were attributed to the synergistic interaction between WO₃ and SO₄ 2 ⁻, resulting in the formation of Lewis-Bronsted acid sites. This study provides important insights into how tungsten affects the structure and acidity of sulfated titania, which could guide the design of more efficient, impurity-tolerant solid acid catalysts for environmentally sustainable chemical processes.

Chiral framework materials offer a promising platform for exploring circularly polarized lasing. However, the creation of chirality in current optical gain framework materials relies on the chirality transfer, which suffers from weak chiral light-matter interactions and thus limits the dissymmetry factors of circularly polarized laser emission. Here, we propose to synthesize homochiral metal–organic frameworks (MOF) from chiral optical gain molecules to enhance chiral light-matter interactions, enabling circularly polarized lasing with large dissymmetry factors. The MOFs are grown controllably into 1D microcrystals to function as Fabry–Pérot cavities providing optical feedback for laser oscillations. In addition, the chiral optical gain molecules in the frameworks exhibit high luminescence efficiencies of ∼88% because the rigid frameworks effectively suppress nonradiative decay, resulting in low-threshold lasing. More importantly, the homochiral optical gain frameworks can enhance chiral light-matter interactions, which allows for circularly polarized laser emission with dissymmetry factors larger than 1.0. Our work establishes a homochiral framework material platform for exploring high-performance circularly polarized lasing.

H 2 O 2 photosynthesis, as a gas-liquid-solid reaction, faces two giant challenges, i.e., charge recombination and sluggish oxygen transport. For improving efficiency, it is a feasible strategy to construct a robust triphase interface with optimized charge kinetics. Herein, we constructed a self-floating covalent-organic framework (COF)-based film with Janus heterostructure, i.e., COF-[NH 2 -GO]. In overall H 2 O 2 photosynthesis, COF-[NH 2 -GO] exhibited the highest yield among COF film and powder, signifying improved separation and transfer of photogenerated carriers. The photocatalytic triphase system achieved 5,306.6 μmol·m −2 ·h −1 H 2 O 2 yield, higher than that of diphase counterpart, ascribed to the promoted O 2 delivery. It was demonstrated that excellent photocatalytic performance was attributed to the improved charge kinetics and mass transfer. A prototypical film-based device was designed for photosynthesis and collection of H 2 O 2 , which exhibited bactericidal activity against Escherichia coli . More importantly, this strategy could be extended to other COFs and functional nanomaterials. This work provides new insights for challenging triphase photocatalysis.

1-Butanol is a C4 aliphatic alcohol that is widely used as a gasoline blendstock. In this study, we report an underexplored metabolic route for the de novo biosynthesis of 1-butanol in Escherichia coli . Specifically, the 1-butanol biosynthetic pathway comprises a redesigned Clostridium -derived pathway for butyryl-CoA synthesis, followed by a CoA-acylating aldehyde dehydrogenase (PduP from Salmonella enterica ) and an endogenous alcohol dehydrogenase (YqhD from E. coli ). We found that abolishing thioesterases to block the formation of butyrate byproduct would lead to deleterious effects on the cell growth. Upon introducing a metabolic buffering pathway towards polyhydroxyalkanoate biosynthesis, the toxicity caused by metabolic imbalance was alleviated, accompanied by enhanced cell growth and 1-butanol productivity. A similar strategy was also validated to be effective for improving the production of hexane-2,3-diol, a potential cosmetic component with high value. In summary, this work successfully demonstrates that the metabolic buffering strategy exerts a synergistic effect on enhancing biochemical production with improved carbon recovery efficiency.

The increasing demand for high-speed X-ray imaging requires scintillators with high light yield and fast response. Perovskite nanocrystals are promising candidates due to their distinctive optical properties and solution processability. However, the fabrication of thick X-ray films, which are several orders of magnitude thicker than conventional optoelectronic devices, leads to severe material waste and reduced light yield caused by strong spectral overlap and self-absorption. In addition, conventional synthesis methods often suffer from low reaction yields and uncontrolled exciton pathways. Here, we develop a low-temperature polar-solvent synthesis method that achieves a reaction yield of 162 mg mL −1 and optimizes exciton routing for improved energy transfer. This approach increases the Stokes shift and reduces the radioluminescence decay to 7.19 ns. Consequently, high-speed X-ray imaging at 7,680 frames per second with a spatial resolution of 27.6 line-pairs per millimeter is achieved, supporting sustainable commercialization of perovskite nanocrystal scintillators for dynamic X-ray imaging.

Covalent organic frameworks (COFs) with long-range ordered periodic structures have emerged as promising photocatalysts for advanced oxidation processes. Herein, we reported a highly crystalline porphyrin-based COF (COF-TAP-Cu) featuring outstanding visible-light-driven oxidation activity. COF-TAP-Cu was obtained via a facile bottom-up metallization strategy that tuned the conjugation and planarity of the porphyrin building block (TAP-H). Incorporation of Ni 2+ or Cu 2+ into TAP-H moderately enhanced the π-conjugation of the resulting metalloporphyrin monomers (TAP-M; M = Ni, Cu), leading to markedly improved crystallinity of the corresponding COFs. Notably, structural analysis indicated that the porphyrin ring in TAP-Ni undergoes pronounced distortion, whereas TAP-Cu retained a near-planar geometry. As a result, COF-TAP-Cu exhibited higher crystallinity and superior photocatalytic oxidation performance compared with the metal-free porphyrin-based COFs (COF-TAP-H) and Ni-anchored porphyrin-based COFs (COF-TAP-Ni). Under visible-light irradiation, COF-TAP-Cu efficiently activated molecular oxygen to produce both O 2 •- ( via electron transfer) and 1 O 2 ( via energy transfer), enabling rapid degradation of sulfadiazine (SDZ) with a removal efficiency of up to 95% within 30 min. This work highlighted a monomer-design strategy that balanced conjugation and planarity to construct highly crystalline porphyrin-based COFs, offering new insights for photocatalytic antibiotic remediation in aquatic environments.

Confining Cu clusters into covalent organic frameworks (COFs) has been revealed to be an effective strategy to enhance the stability of Cu clusters for the electrocatalytic conversion of carbon dioxide (CO₂) to ethylene (C 2 H 4 ). However, this strategy still exhibits unsatisfactory selectivity and efficiency. Herein, the reaction of a trinuclear Cu-cluster-based building unit, tris(4-μ 2 -O-carboxaldehyde-pyrazolato-N, N′)-tricopper (Cu 3 ), with a 4-connected square-planar linker of 4,4′,4”″,4″′-(pyrene-1,3,6,8-tetrayl)tetraaniline (Py) afforded a trinuclear Cu-cluster-containing three-dimensional (3D) COF, named 3D-Cu 3 -Py-COF. Powder X-ray diffraction combined with theoretical simulations reveals the crystalline nature of 3D-Cu 3 -Py-COF with a tbo topology. Comparative studies demonstrate that the 3D framework of 3D-Cu 3 -Py-COF enhances the exposure of active sites and improves CO 2 adsorption capacity. This, in cooperation with the capacity of trinuclear Cu-cluster moieties to facilitate C C coupling, endows 3D-Cu 3 -Py-COF with excellent electrocatalytic performance and selectivity for CO₂ reduction reaction (CO₂RR) to C 2 H 4 , exhibiting a maximal Faraday efficiency of 44.6% for C 2 H 4 at −0.8 V vs. reversible hydrogen electrode. This work should be helpful for the strategic design and fabrication of efficient Cu-cluster-based electrocatalysts for promoting the conversion of CO₂ into valuable carbon-based fuels.

In colloidal mixtures, different particle types coexist in the same suspension environment yet exhibit intrinsically distinct surface chemistries. Here we present surface-dictated sorting rules that enable selective assembly among mixed colloids. Using seven types of particles of equal size (∼2 μm) representing common families of negatively charged stable colloids, including inorganic spheres bearing native surface hydroxyls groups (M–OH, e.g. SiO 2 , TiO 2 ) or grafted carboxyl groups, organic polymer particles synthesized by emulsion polymerization (sulfonated PS and PMMA, carboxylated PS), and an organosilane-derived colloid with silanol surface (TPM), we identify three general strategies: (1) pH and solvent dielectric tuning, suppresses the dissociation of weakly acidic surface groups, driving particles with near-neutral M–OH or –COOH sites to clusterize; (2) Small molecules with multiple hydrogen-bonding sites (i.e., urea), reorganize interfacial hydrogen-bond networks, selectively destabilizing the surfaces of hydroxyl-rich inorganic particles; (3) Depletion-driven assembly with Pluronic surfactants. Upon selective adsorption onto hydrophobic particles (e.g., polystyrene), Pluronic copolymers form a stable surface brush layer, increasing the effective radius of the particles. This expanded depletion zone creates greater overlap as particles approach, resulting in enhanced depletion attraction. When combined with disparities in intrinsic surface potential, this brush-mediated interaction yields distinct overall potentials between hydrophobic and hydrophilic particles, thereby driving the preferential assembly of the hydrophobic ones. Applying this strategy to SiO 2 /Pt Janus particles further induces neutral charged Pt-facet clustering under depletion, yielding oriented clusters and chain-like assemblies.

Covalent organic frameworks (COFs) are promising photocatalysts for hydrogen peroxide (H 2 O 2 ) production, yet their rational design remains challenging. Although machine learning has advanced the prediction of properties of porous materials, its application to COF-based photocatalysis faces two major challenges: the representation of multilevel structural features and the limited availability of training datasets. Here we present a comprehensive computational framework, termed ‘information co-evolution’, that accelerates the discovery of efficient COF structures for H 2 O 2 photosynthesis. This framework integrates two pathways: to mitigate data limitations, we introduce data augmentation techniques and ensemble modelling; concurrently, to address the structural encoding challenge, we introduce a cross-level feature fusion strategy that integrates these fragment descriptors with mechanism-driven physical descriptors. These strategies collectively reduced the validation root mean square error from 4.70 to 3.31. Among over 10,000 candidates, our framework can successfully identify high-performance COFs for H 2 O 2 photosynthesis, for example, COF-343 achieves a H 2 O 2 photosynthetic rate of 12,978.7 μmol h −1 g −1 . The model interpretation further unveiled critical structural motifs, offering information for the rational design of COF photocatalysts beyond traditional trial-and-error methods.

CA-125, as a tumor marker for ovarian cancer, plays an importance role for rapid and sensitive detection in early diagnosis. Herein, a label-free electrochemical immunosensor based on COF/PTh/MB nanocomposite was constructed for the detection of CA-125.The TAPB-DMTP-COF material, with its large surface area and stable porous framework, was used as the substrate. However, its poor conductivity hindered electron transfer. To address this, conductive polymer PTh was combined with the COF to enhance the composite's conductivity. Meanwhile, MB was used as a signal probe, and differential pulse voltammetry (DPV) was adopted to measure the electrochemical signal. Under optimized experimental conditions, the proposed immunosensor exhibited excellent performance for the CA-125 detection, with a detection range of 1 mU/mL-10000 mU/mL, and a low detection limit of 0.34 mU/mL (S/N = 3), providing a potential platform for clinical application.

In this study, a new method for preparing surface enhanced Raman scattering detection material based on membrane was proposed. First, Zeolitic imidazolate framework-67 was modified on a polypropylene membrane by in-situ growth. Subsequently, Ag nanoparticles were modified on the membrane by in-situ synthesis. After characterization by scanning electron microscopy, energy dispersive spectrometer, infrared spectrometer, x-ray diffractometer, x-ray photoelectron spectrometer and so on, it could be proved that Zeolitic imidazolate framework-67 and Ag nanoparticles were successfully modified on the surface of polypropylene membrane. The polypropylene membrane modified with Ag nanoparticles@Zeolitic imidazolate framework-67 prepared by the in-situ method has the advantages of good uniformity and stability of Zeolitic imidazolate framework-67 and Ag nanoparticles. Based on the polypropylene membrane modified with Ag nanoparticles@Zeolitic imidazolate framework-67, sample loading and surface enhanced Raman scattering detection of methylene blue could be completed within 3 min. As a result, the analysis time, on-line, real-time and practicality of surface enhanced Raman scattering detection was improved. In the analysis of real samples, compared with the polypropylene membrane modified with Ag nanoparticles@methyl-sulfur functionalized Zeolitic imidazolate framework-67 prepared by the covalent method, the polypropylene membrane modified with Ag nanoparticles@Zeolitic imidazolate framework-67 prepared by the in-situ method also showed better surface enhanced Raman scattering detection performance.
