Transition metal sulfides have been widely used as anode electrodes of lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs) due to its high theoretical capacity and low price. However, problems of huge volume expansion and poor conductivity during charging and discharging have been emerged. Herein, we design a N, C-co-doped, nano-sized, and hollow carbon-coated ZnS (ZnS-NC@C) composite using the advantages of metal organic framework (zeolitic imidazolate framework-8) structure and resorcinol-formaldehyde coating. When applied as anodes of LIBs and SIBs, it displays a high reversible capacity of 748 and 150.9 mAh g−1 after 500 cycles at the current density of 1.0 A g−1, respectively. This work could provide a promising strategy for enhancing the performance of transition metal sulfides for potential applications in LIBs and SIBs.

The presence of organic dyes in aquatic systems poses a significant threat to ecosystems and human well-being. Due to recycling challenges, traditional commercial activated carbon is not cost-effective. To address this, an imidazolate acid zeolite framework-8 (ZIF-8)-modified magnetic adsorbent (ZMPLB-800) was synthesized through the in-situ formation of ZIF-8 and subsequent carbonization at 800 °C, using magnetic pineapple leaf biochar (MPLB) as a carrier. The porous structure of ZMPLB-800 facilitates the rapid passage of dye molecules, enhancing adsorption performance. ZMPLB-800 exhibited remarkable adsorption capacity for methylene blue (MB) across a pH range of 3–13, with a maximum adsorption capacity of 455.98 mg g −1 . Adsorption kinetics and thermodynamics followed the pseudo-second-order kinetic model and Langmuir isotherm model. Mechanisms of MB adsorption included pore filling, hydrogen bonding, electrostatic interactions, π-π interactions, and complexation through surface functional groups. Additionally, ZMPLB-800 demonstrated excellent regeneration performance, recording a removal efficiency exceeding 87% even after five adsorption/desorption cycles. This study provides a novel strategy for treating dye wastewater with MOF composites, laying the foundation for waste biomass utilization. Graphical

Efficient utilization of solar energy has received tremendous attention due to the increasing environmental and energy concerns. In this paper, a plasmonic photocatalyst integrated with metal–organic framework (MOF) material, Ag/AgCl@ZIF-8, was fabricated for the first time. The unique hetero-junction structure of Ag/AgCl@ZIF-8 greatly enhanced its photocatalytic activity. Selecting RhB as a model pollutant, 98% of RhB can be degraded after 16 min under solar radiation. The relationship between the photocatalytic activity and the structure of Ag/AgCl@ZIF-8 hybrid materials was discussed and the possible reaction mechanism was proposed. The high photocatalytic activity of the hybrid material under solar radiation revealed its great application potential in directly harvesting solar energy to solve the environmental pollution issues.

Diabetic wounds represent one of the most prevalent complications in patients with diabetes mellitus. Elevated reactive oxygen species (ROS), bacterial infections, persistent inflammation, and impaired angiogenesis collectively contribute to delayed diabetic wound healing. In this study, a multifunctional, injectable, photoinitiator-free, photocrosslinkable hydrogel (G/Z@M) based on insect-derived chitosan was developed. The hydrogel system incorporated lipoic acid (LA), which possesses photopolymerization capability and potent antioxidant activity, to modify quaternized chitosan (QMCS). Through self-initiated photo-crosslinking of QMCS-LA, the hydrogel's three-dimensional network was constructed. Simultaneously, the ZIF-8@MPN nanocomposite was constructed by coating ZIF-8 with a metal-polyphenol network (MPN) functional coating formed through the coordination of epigallocatechin gallate (EGCG) with Ga 3+ . This nanocomposite was then loaded onto the QMCS-LA network. Both in vitro and in vivo experiments demonstrated that the G/Z@M hydrogel possesses great biocompatibility, antibacterial, anti-inflammatory, antioxidant, and pro-angiogenic activities, effectively promoting the healing of full-thickness skin defect wounds in MRSA-infected diabetic rats. In conclusion, the G/Z@M hydrogel presents an innovative therapeutic approach for diabetic infected wounds by simultaneously regulating oxidative stress, bacterial infection, persistent inflammation, and impaired angiogenesis.

Lithium-sulfur batteries (LSBs) are considered a promising class of energy storage devices due to their high theoretical energy density and specific capacity. Key challenges to improving LSB performance include mitigating the shuttle effect of soluble polysulfides (LiPSs) and enhancing the conductivity of the sulfur cathode. In this study, we present a tubular material composed of porous nitrogen-doped carbon (PNC) and nitrogen-doped carbon nanotubes (NCNT) as a sulfur host (PNC/NCNT). The porous structure of PNC/NCNT provides abundant space for sulfur accommodation, while its disordered mesoporous structure and high electronic conductivity help alleviate the shuttle effect of LiPSs through nitrogen-induced defects and active sites. As a result, the PNC/NCNT/S cathode significantly enhances the poor electrical conductivity of sulfur cathodes, offering improved rate performance and robust cycling stability, with a capacity retention of 859.1 mAh g −1 after 500 cycles at 1 C and a minimal capacity fading of 0.031 % per cycle.

The clinical translation of urolithin A (UA), an ellagitannin-derived metabolite with antioxidant and mitophagy-inducing properties, is hampered by its poor solubility, limited stability, and low oral bioavailability. To address these limitations, we developed a core-shell nanoplatform (UA@ZIF-8@CMG) comprising a ZIF-8 core for efficient encapsulation and a carboxymethyl β-glucan (CMG) shell for enhanced stability and potential targeting. The optimized formulation exhibited a high drug-loading capacity (12.65 %), markedly improved UA stability, and demonstrated pH-responsive release, with minimal leakage (22 %) under simulated gastric conditions followed by sustained release in the intestinal environment. In vitro studies revealed reduced cytotoxicity and a dual cellular uptake mechanism, involving putative Dectin-1-mediated endocytosis in macrophages and nonspecific uptake in intestinal cells. This uptake profile resulted in superior preservation of mitochondrial membrane potential and more effective ROS scavenging compared with free UA. The key innovation of this system lies in the synergistic ZIF-8@CMG architecture, which integrates robust protection, controlled release, and cell-type-specific uptake, thereby distinguishing it from previously reported delivery platforms. Collectively, this work presents a translatable strategy to enhance UA bioavailability and therapeutic performance, underscoring its promise for both nutraceutical and pharmaceutical applications.

In this study, modified hollow e-ZIF-8 nanoparticles with a hollow structure and hydroxyl-rich surface were ingeniously synthesized through a one-step etching method, thereby increasing the contact area and addressing the issue of stacking imprinting sites, fundamentally enhancing selectivity. Among these, the hollow structure of the e-ZIF-8 nanoparticles not only increased the interlayer spacing of the graphene oxide (GO) nanosheets, providing additional pathways for water molecules, but also, through π-π interactions, cross-linked the phenol-modified nanoporous metal-organic frameworks (MOFs) with the GO nanosheets, significantly enhancing the structural stability and anti-fouling capability of the composite membrane. The effects of different e-ZIF-8 addition amounts on membrane flux and hydrophilicity were investigated, constructing a GO-based imprinting structure on the stacked e-ZIF-8/GO nanosheet surfaces, offering a novel strategy to improve the selectivity and stability of the membrane. The maximum adsorption capacity of e-MG-IMs reached 38.35 mg g −1 , demonstrating good selective separation factors ( α RBV/ACV = 3.24, α RBV/AZT = 2.41 and α RBV/LAM = 4.21), as well as excellent permeation selectivity ( β ACV/RBV = 4.75, β AZT/RBV = 4.42 and β LAM/RBV = 5.92). In this study, the optimized regulation of GO nanosheets extended the molecular transport channels, facilitating the construction of more molecular recognition sites, thus positively impacting the separation performance of the imprinting membrane.

The development of high-performance mixed matrix membranes (MMMs) with satisfactory structure stability has attracted much attention for the past few years. The rational design and synthesis of fillers to well coordinate themselves in the polymeric matrix is still challenging. The core-shell structured fillers were synthesized via the heteroepitaxial growth of ZIF-8 on ZIF-L(Co) surface (ZIF-L(Co)@ZIF-8), which were then embedded into Pebax to fabricate MMMs for enhanced CO 2 /CH 4 separation. The synthesized fillers and MMMs were characterized via SEM with EDS mapping, TEM, XRD , FIIR and nanoindentation measurements. The effects of ZIF-L(Co)@ZIF-8 loading and filler components on gas separation performance were studied with the evaluation of membrane stability. The experimental results indicated that the filled ZIF-L(Co)@ZIF-8 could be evenly distributed within the bulky Pebax. The synergistic effect of the core-shell structured fillers in adsorption and molecular sieving endowed the synthesized MMMs with superior gas separation performances. The optimal separation performance is achieved for the MMM containing 3 wt% of ZIF-L(Co)@ZIF-8 with a CO 2 permeability of 145.7 Barrer and a CO 2 /CH 4 selectivity of 40.9, corresponding to 79.1% and 110.1% increases over pure Pebax membrane.

A novel nitrogen-doped porous carbon catalyst (NCW) was synthesized via in-situ growth of ZIF-8 on balsa sawdust followed by controlled carbonization. The integration of ZIF-8 significantly increased specific surface area, defect density, and electrochemical activity, while nitrogen incorporation—especially pyridinic and graphitic species—enhanced 2e − oxygen reduction reaction (ORR) selectivity, achieving an exceptional H 2 O 2 selectivity of 94%. When immobilized on a graphite cathode and paired with a boron-doped diamond (BDD) anode, the NCW-based electro-Fenton (EF) system enabled robust in-situ H 2 O 2 generation and efficient tetracycline (TC) degradation. Under optimized conditions, the system achieved a maximum H 2 O 2 accumulation of 0.73 mmol L −1 , completed TC removal within 120 min, and a total organic carbon (TOC) mineralization efficiency of 84.6% after 4 h. Quenching experiments and electron paramagnetic resonance (EPR) spectroscopy identified homogeneous and heterogeneous hydroxyl radicals (·OH) and superoxide radicals ( ‐ O 2 · ‐ ) as the key reactive species. The NCW/BDD/EF system demonstrated excellent versatility across various organic pollutants and maintains robust reusability over multiple cycles. This work presents a sustainable strategy for developing wood-derived electro-Fenton catalysts for efficient antibiotic wastewater treatment.

ZIF-8 improves HTO dispersion and ion transport within the cellulose aerogel. • ZIF-8/HTO@CA achieves 29.85 mg/g Li + uptake and 58.62% brine extraction. • Li + selectivity is governed by HTO recognition, dehydration, and lattice migration. Selective lithium recovery from high-Mg/Li salt-lake brines remains challenging because of competing ions and slow ion transport. In this study, a ZIF-8-functionalized H 2 TiO 3 (HTO)/cellulose composite aerogel (ZIF-8/HTO@CA) was prepared for Li + adsorption. The cellulose aerogel provided a three-dimensional support for particle immobilization and recovery. ZIF-8 improved HTO dispersion and provided additional transport interfaces. The composite had a specific surface area of 117.89 m 2 ·g −1 and retained a mesoporous structure. Its Li + adsorption capacity reached 29.85 mg·g −1 at pH 11 and 298 K. Nonlinear isotherm fitting showed that the Langmuir model gave a better description of the equilibrium data, with a fitted maximum capacity of 34.53 mg·g −1 . Both pseudo-first-order and pseudo-second-order models reasonably described the adsorption kinetics. Competitive adsorption tests showed preferential Li + uptake over Na + , K + , Mg 2+ , and Ca 2+ . The Li + /Mg 2+ separation factor increased from 46.29 for pristine HTO to 80.33 for ZIF-8/HTO@CA. In natural salt-lake brine with an initial Mg/Li mass ratio of 706, the composite achieved a single-stage Li + extraction efficiency of 58.62% without additional pH adjustment. The adsorption efficiency was 77.34% after the sixth adsorption–desorption cycle. Zeta-potential measurements and DFT calculations suggest that Li + selectivity mainly originates from the intrinsic recognition of HTO and the combined effects of ion dehydration and lattice migration. ZIF-8 mainly improves particle dispersion, accessible interfaces, and ion transport. These results demonstrate the potential of ZIF-8/HTO@CA for lithium recovery from complex brines.

Multilayer PVDF membrane with TiO₂/ZIF-8 and CS-SDAEM brush. • Superhydrophilic: water contact angle drops to 0° within 1.3 s. • Pure water flux 1440 L·m⁻²·h⁻¹ and dye rejection over 93%. • Synergy enables > 93% flux recovery after 10 cycles without cleaning. • Excellent stability against ultrasonication, abrasion, and harsh chemicals. Conventional polymer separation membranes suffer from severe fouling, limiting their efficiency in wastewater treatment. To address this issue, we develop a multilayer-modified PVDF membrane by integrating a TiO₂/ZIF-8 photocatalytic layer and a CS-SDAEM zwitterionic polymer brush. The TiO₂/ZIF-8 nanoparticles are deposited on the membrane surface, followed by crosslinking and grafting of CS-SDAEM, which forms a robust hydration layer and physically encapsulates the nanoparticles. The resulting membrane exhibits superhydrophilicity (water contact angle drops to 0° within 1.3 s) and achieves a pure water flux of 1440 L·m⁻²·h⁻¹ with over 93% dye rejection for various dyes. Owing to the synergistic adsorption, photocatalysis, and antifouling effects, the membrane shows excellent self-cleaning ability, maintaining a flux recovery rate > 93% after 10 photocatalytic cycles without chemical cleaning. In addition, it exhibits excellent mechanical and chemical stability when subjected to ultrasonication, abrasion, and exposure to aggressive chemicals. This multilayer strategy offers a promising route to construct high-performance, long-lasting separation membranes for advanced water treatment.

A solvent-free BDB@ZIF-8 nanofluid was successfully synthesized and characterized. • The nanofluid exhibited liquid-like behavior and excellent dispersibility in epoxy resin. • The dual transfer film composed of iron oxides, a carbon-rich layer, and a liquid phase formed on the worn surface. • The friction coefficient and wear rate of BDB@ZIF-8 nanofluid reinforced resin composites reduces by 24.3% and 70.97% compared with pure resin. An innovative solvent-free route was developed for fabricating bamboo-derived biochar @Zeolitic Imidazolate Framework-8 nanofluids (code as: BDB@ZIF-8 NFs) via electrostatic assembly of BDB with ZIF-8, culminating in the covalent conjugation of a KH560-M2070 outer shell. The resulting NFs exhibited liquid-like behavior and hybrid organic-inorganic characteristics, leading to an excellent dispersibility within epoxy resin matrix. A comparative study on the tribological performance of resin composites reinforced with various fillers revealed that the BDB@ZIF-8 NFs provided the most significant enhancement. The synergy between the BDB@ZIF-8 core and its KH560-M2070 shell underpins this enhanced performance. The possible mechanisms are as follows: BDB and ZIF-8 act as fillers and rollers on the worn surface, thereby decreasing resin wear. Meanwhile, owing to the presence of the nanofluid, the friction mode during relative motion shifts from dry friction to boundary friction, resulting in a reduced friction coefficient (COF). On the other hand, a dual transfer film composed of iron oxides, a carbon-rich film derived from BDB nanosheets, and a liquid phase is squeezed out of the matrix onto the worn surface. These films collectively enhance the lubricity and durability of the composite. Download: Download high-res image (312KB) Download: Download full-size image
