The Bayer process is the primary method for alumina production. However, thiosulfate ions (S 2 O 3 2− ) present in the involved sodium aluminate solution are difficult to remove and adversely affect this process, thereby limiting the large-scale application of high‑sulfur bauxite. To address this issue, this study designed and synthesized a composite photocatalyst Co-TiO 2 @C based on ZIF-8-derived porous carbon as a carrier. Moreover, the study combined wet oxidation and photocatalytic oxidation to investigate the photocatalytic S 2 O 3 2− degradation activity and stability of this photocatalyst in a sodium aluminate solution. Results indicated that the ZIF-8-derived porous carbon carrier had a high specific surface area and highly porous structure, which were conducive to the loading and dispersion of Co-TiO 2 catalytic components. Moreover, it formed a composite photocatalytic material with good adsorption performance and abundant active sites. High-temperature pyrolysis led to the formation of graphite structures with excellent electron transfer properties on porous carbon supports, while Co doping reduced the bandgap energy of the loaded nano-TiO 2 , resulting in excellent photocatalytic performance of the composite catalyst under visible-light irradiation (The bandgap is 2.78 eV, and the photocurrent density under xenon lamp can reach 2.41 μA/cm 2 ). The adsorption degradation of S 2 O 3 2− ions by Co-TiO 2 @C/900 reached 29.6% within 30 min. After 60 min of light irradiation, the photocatalytic degradation rate of S 2 O 3 2− ions by Co-TiO 2 @C/900 can reach 92.5% under xenon lamp irradiation, which is 38.4% higher than that of P25. Moreover, the degradation efficiency of S 2 O 3 2− ions by Co-TiO 2 @C/900 only decreased by 9.5% after 6 cycles of experiences. The results of quenching experiments and paramagnetic electron resonance indicated that the degradation mechanism of S 2 O 3 2− depended on the generation of reactive oxygen species, such as hydroxyl radicals and superoxide radicals, under light irradiation.

Ultralight aerogels with low bulk density, highly porous nature, and functional performance have received significant focus in the field of water pollution treatment. Here, high-crystallinity, large surface-aera metal frame-work (ZIF-8) was efficiently utilized to assist in the preparation of ultralight yet highly oil and organic solvent adsorption capacity, double-network cellulose nanofibers/chitosan-based aerogels through a physical entanglement and scalable freeze-drying approach. After chemical vapor deposition with methyltrimethoxysilane, a hydrophobic surface was obtained with a water contact angle of 132.6°. The synthetic ultralight aerogel had low density (15.87 mg/cm 3 ) and high porosity (99.01 %). Moreover, the aerogel had a three-dimensional porous structure, which endowed it with high adsorption capacity (35.99 to 74.55 g/g) for organic solvent, and outstanding cyclic stability (>88 % of the adsorption capacity after 20 cycles). At the same time, aerogel removes oil from various oil/water mixtures by gravity alone and has excellent separation performance. This work holding excellent properties in terms of convenient, low-cost, scalability to manufacture environmentally friendly biomass-based materials for oily water pollution treatment.

Silicon (Si) shows great potential for lithium-ion batteries (LIBs) due to its high theoretical capacity and low working potential. However, its intrinsic low electronic conductivity and large volume expansion during lithiation result in dramatic capacity fading and poor rate capability. Herein, a dual-confinement strategy is proposed for improving the lithium storage properties of Si by uniformly anchoring Si nanoparticles within a MXene/ZIF-8 derived carbon framework. In the Si/MXene@C composite, Si nanoparticles tightly bond with MXene and carbon through the formed interfacial Si–O–Ti and Si–C bonds, respectively, which is beneficial for alleviating the volume expansion of Si and promoting the interfacial charge transfer. Therefore, the Si/MXene@C composite exhibits excellent lithium storage performances in terms of high capacity (1006.1 mAh g–1 at 100 mA g–1), stable cycle performance (862.9 mAh g–1 after 150 cycles at 100 mA g–1), and superior rate capability (233.3 mAh g–1 at 5 A g–1), indicating its promising potential as an anode material for next-generation high-performance LIBs.

The unique features of high porosity, shape selectivity, and multiple active sites make metal–organic frameworks (MOFs) promising as novel stationary phases for high-performance liquid chromatography (HPLC). However, the wide particle size distribution and irregular shape of conventional MOFs lead to lower column efficiency of such MOF-packed columns. Herein, the fabrication of monodisperse MOF@SiO 2 core–shell microspheres as the stationary phase for HPLC to overcome the above-mentioned problems is reported. Zeolitic imidazolate framework 8 (ZIF-8) was used as an example of MOFs due to its permanent porosity, uniform pore size, and exceptional chemical stability. Unique carboxyl-modified silica spheres were used as the support to grow the ZIF-8 shell. The fabricated monodisperse ZIF-8@SiO 2 packed columns (5 cm long × 4.6 mm i.d.) show high column efficiency (23 000 plates m −1 for bisphenol A) for the HPLC separation of endocrine-disrupting chemicals (bisphenol A, β-estradiol, and p -( tert -octyl)phenol) and pesticides (thiamethoxam, hexaflumuron, chlorantraniliprole, and pymetrozine) within 7 min with good relative standard deviations for 11 replicate separations of the analytes (0.01–0.39, 0.65–1.7, 0.70–1.3, and 0.17–0.91 % for retention time, peak area, peak height, and half peak width, respectively). The ZIF-8@SiO 2 microspheres combine the advantages of the good column packing properties of the uniform monodisperse silica microspheres and the separation ability of the ZIF-8 crystals. Graphical Core strength : Monodisperse ZIF-8@SiO 2 (ZIF-8=zeolitic imidazolate framework 8) core–shell microspheres have been fabricated through controllable growth of a ZIF-8 shell on spherical carboxylate-terminated SiO 2 cores (see figure). The metal–organic framework material is suitable as a stationary phase for fast and highly efficient HPLC separation.

Bead-like PAN/ZIF-8 nanofiber membranes, of which the commercial ZIF-8 nanoparticles attached to the surface of PAN nanofibers, were prepared by a simple one-step electrospinning method. The fiber structures, electrospinning parameters and adsorption capacity to methyl blue were investigated. ZIF-8 distributed uniformly on the nanofiber, and the adsorption process followed the pseudo-second-order kinetics. Maximum adsorption capacity was obtained as 224.37 mg/g at ZIF-8 concentration of 10 wt%, methyl blue concentration of 100 mg/L, and time of 180 min. Our work provides a simple, cost-effective process for the fabrication of MOFs nanofiber membranes with good adsorption capacity that suitable for practical commercial applications.

Metal-organic framework (MOF)-based membranes show promising potential for gas separation. However, it remains challenging to fully exploit the synergistic advantages of MOF crystals and polymers for fabricating highly loaded mixed matrix membranes (MMMs). Herein, a highly loaded ZIF-8 ultrathin MMM was prepared in situ via a stepwise growth strategy. Driven by the diffusion rate difference between the ligand and polyethyleneimine (PEI-600), preferentially formed ZIF-8 crystals served as the dominant phase, while the subsequently developed PEI-Zn 2+ crosslinked network acted as an intergranular densification phase. Owing to the reduction in ZIF-8 crystal size induced by PEI, the MMMs exhibited an ultrathin thickness of only 160 nm. Furthermore, PEI enhanced the molecular sieving ability of crystals and membrane's CO 2 /N 2 solubility selectivity by regulating the pore structure and membrane composition. With a high ZIF-8 loading of 84.3 %, the resulting MMMs demonstrated an excellent CO 2 permeance of 3177.4 GPU, accompanied by a CO 2 /N 2 selectivity of 36.9. Notably, it maintained stable separation performance after bending and during long-term operation, showing good processability and industrial application potential. This strategy not only reinforces the advantages of MOF-based gas separation membranes but also provides a new paradigm for fabricating highly loaded MMMs.

In nanomaterials containing multiple metal atoms, interactions between metal atoms can generate the Fenton effect, making them a novel antibacterial agent that combines photodynamic and chemodynamic properties. However, conventional single-atom or multi-atom nanomaterials are limited by their specific surface area and porosity, resulting in relatively low photocatalytic efficiency. Herein, we developed a nanzyme antibacterial agent based on a porous ZIF-8 metal-organic framework incorporated with Pt and CuS via a straightforward method. Under low-concentration near-infrared (NIR) light irradiation, the CuS enables the nanzyme to rapidly raise the reaction system temperature to about 50 °C within 5 min. Furthermore, facilitated by charge transfer between Cu and Pt metals and the prominent Fenton-like activity of Pt, the system efficiently catalyzes hydroxyl radical generation from trace amounts of H 2 O 2. This mechanism synergistically integrates photodynamic and chemodynamic actions for antibacterial efficacy. The designed CuS@Pt@ZIF-8 nanzyme achieves a bacterial elimination rate of over 95% against common bacteria when subjected to irradiation with 808 nm NIR light. In vivo experiments in mice demonstrated a wound healing rate of up to 98% within 7 days. Additionally, experiments on plants and animals demonstrated that this nanzyme has minimal toxicity. The broad-spectrum Fenton-like catalytic system provide an efficient strategy for drug-resistant bacterial wound infections under combined photodynamic and chemical dynamics therapy, offering a new avenue for the development of clinical drugs.

Hypoxia is one of the common characteristics in tumor cells. It has been confirmed that the nitro reductase (NTR) overexpression is closely related to hypoxia cells. Thus, developing a facile method to detect nitro reductase is of great significance. Although several detection techniques have been designed for the NTR, these probes still have limitations, such as low sensitivity, poor water solubility, and compromised biocompatibility. In this study, we developed a nanocomposite (Nitro-BOD@ZIF-8) based on BODIPY fluorophore and zeolitic imidazolate framework-8 (ZIF-8). A red emission BODIPY small molecule probe (Nitro-BOD) was synthesized and then encapsulated in ZIF-8. Morpholine and nitro groups were introduced to Nitro-BOD for lysosome localization and NTR detection, respectively. The results showed that reduction of the nitro group on the probe by NTR blocked the photoinduced electron transfer (PET), resulting in fluorescence enhancement. The low detection limit for the NTR proved the sensitivity of the sensor. In addition, confocal microscopy con-firmed the fluorescence imaging feature of the Nitro-BOD@ZIF-8 for NTR in A549 cells. This work also opens a useful path for probe and MOF in the field of enzyme detection.

Multi-layer graphene oxide (GO) membranes show great perspective in vast fields due to special two-dimensional structure. However, pure GO membranes generally face main obstacles of low flux, weak interlayer interaction and poor stability, which hinder their wide application in separation. Introduction of nano-porous crystals into interlayer of GO nanosheets to form 3D/2D structure is a potential strategy to overcome these issues. In this study, novel polyphenol etched hollow MOF/GO composite membrane was first synthesized employing modified hollow metal organic frameworks with strong hydrophilicity and hollow structure by one-step etching-aided cross-linking method. MOF nanoparticles with hollow structure expanded interlayer spacing of GO nanosheets and brought about formation of additional water channels, significantly reducing water transfer resistance. Meanwhile, nano-porous crystal MOFs modified by phenolic materials were able to cross-link adjacent GO nanosheets via π–π interfacial interactions to achieve stable structure and increase anti-swelling property of membranes. The pores with abundant hydroxyl groups provided strong free energy barrier for ions at medium and low concentrations of ionic strength , therefore not only greatly improved membrane permeaselectivity, but also enhanced anti-fouling performance. The prepared eZIF-8/GO nanofiltration membrane exhibited excellent permeate flux of 16.4 L m −2 h −1 bar −1 , 382% higher than pure GO membrane, and competitive Na 2 SO 4 rejection of 86.3%. By simply adjusting GO loading to further reduce membrane thickness, the permeate flux reached up to 45.4 L m −2 h −1 bar −1 with high rejection more than 99% for organic molecules. These results indicate that novel MOF/GO composite membranes have broad application prospects in desalination and water treatment.

The release of textile dyeing wastewater results in significant environmental pollution and endangers human health. Membrane separation technology offers distinct advantages in textile wastewater treatment due to its energy efficiency, high performance, and excellent separation capabilities. This study demonstrates a facile MOF-polymer hybrid membrane fabrication strategy through amine-enhanced interfacial coordination. The introduced –NH 2 groups via Noria and polyethyleneimine (PEI) co-deposition would chelate metal ions, which enhances the heterogeneous nucleation and the compatibility of metal–organic framework (MOF) and polymer. The optimized membrane exhibits superior dye sieving performance, achieving Congo red rejection of 98.9% and water permeance of 23.2 L m -2 h −1 bar −1 . Microstructural analysis reveals dense intergrown zeolitic imidazolate framework-8 (ZIF-8) architectures, validating the co-deposition approach as an effective surface engineering protocol for constructing continuous MOF-polymer hybrid membranes with defect-free interfaces. The membrane also shows superior operational stability at different pH levels and during long-term operation, which shows great potential for practical application.

Microalgal carbon sequestration offers a promising pathway for CO 2 mitigation, yet its efficiency is largely constrained by inherently low gas-liquid mass transfer. Herein, we report an interfacial engineering strategy to construct a ZIF-8/MXene composite membrane via pressure-assisted filtration. The membrane features unique hydrophilic–hydrophobic channels, wherein hydrophilic MXene nanosheets and hydrophobic ZIF-8 nanosheets act synergistically to effectively decouple bubble refinement from mass transfer resistance. This structural design enables the stable generation of monodisperse CO 2 nanobubbles with a mode diameter of 118.2 nm and the concentration of 1.62 × 10 9 particles mL −1 . The potential electrostatic adsorption facilitated by natural divalent cations in the BG-11 medium significantly shortens the mass transfer distance. Consequently, this promotes the formation of a localized CO 2 pseudo supersaturated microenvironment around the microalgae. This localized CO 2 enrichment potentially downregulates the carbon-concentrating mechanism, suggesting a strategic reallocation of cellular energy toward accelerated biomass accumulation. Consequently, the integrated system achieves an unprecedented biomass productivity of 0.76 g L −1 , offering an innovative material-biological paradigm for light-driven carbon capture and utilization.
