A good approach to addressing global warming and the energy crisis is to use semiconductor photocatalysts for water splitting to produce valuable fuels such as hydrogen. In this study, different photocatalysts (ZIS1, ZIS2, ZIS3 and ZIS4) derived from different degrees of sulfidation of In-MOFs were made via the hydrothermal method . Among them, ZIS2 owned the best photocatalytic hydrogen production performance (3.45 mmol h −1 g −1 ). Additionally, this study also investigated the photocatalytic hydrogen production performance of ZIS2 in tetracycline (TC) wastewater systems. In 10 mg L −1 of TC wastewater, the H 2 generation rate reached 98.34 μmol g −1 , and 95.27 % of the TC was removed after 4 h. Characterization techniques revealed that the hollow tubular structure in ZIS2 sample played a crucial role in internal charge transport, thereby influencing the photochemical reaction of photogenerated particles. The research on the structure-properties of the ZIS2 hollow tubular was expanded in the field of photocatalytic application, and its possible use in the area of solar fuel transition was also expanded.

Drug-resistant bacterial infections and biofilm formation have long posed significant challenges to public health, particularly in the context of chronic wound healing. In this study, the CuHspMOF were derived from copper and hesperitin (Hsp). The photocurable Epsilon-poly-l-lysine (EPLMA) and blueberry anthocyanin (BA) were synthesized through free radical polymerization. The multifunctional EB@CuHsp hydrogel exhibits excellent photothermal effect. One of the key features of the EB@CuHsp hydrogel is its ability to monitor the healing environment through color changes in response to variations in pH. This property allows for real-time assessment of the wound’s pH levels, reflecting the body fluid’s pH range during the healing process (pH 5–9). The hydrogel components work synergistically to facilitate wound healing. The EPLMA, with its positively charged, could captures bacteria and enable copper ions to eradicate bacteria at lower concentrations. This dual action leads to the creation of an optimal healing environment conducive to wound healing. During the inflammatory phase, BA and Hsp could collaborate to combat inflammation, which transited from the inflammatory stage to the proliferative phase soon. Continuous release of BA and Cu 2+ , coupled with thermotherapy, significantly enhances epithelial and blood vessel regeneration, thereby expediting the healing of chronic wounds. Overall, this multifunctional composite hydrogel holds great promise for promoting the regeneration of infected wound tissue, making it a potential candidate for chronic wound dressings.

Thermochemical energy storage technology stands as a promising avenue to address the intermittent and fluctuating nature of solar energy. However, it poses significant challenges due to the inadequate adsorption performance of adsorbents and limited heat and mass transfer capacity. In this research, a composite adsorption heat storage material, denoted as AF-CNT-Mg, was successfully synthesized, demonstrating high water adsorption and excellent heat transfer capacity. This material was developed using aluminum fumarate (AF) and multiwalled carbon nanotubes (CNT) as a composite matrix, with magnesium sulfate acting as impregnated hygroscopic salt. The influence of CNT content and magnesium sulfate mass fraction on thermal conductivity and water adsorption properties was thoroughly investigated. Results indicate that increasing CNT concentration enhances heat storage performance while diminishing water adsorption performance. Consequently, an AF-CNT matrix with a CNT mass fraction of 0.2 wt% was chosen as the composite matrix. The texture and thermal properties of AF-CNT-Mg composites were analyzed through automated specific surface area and pore size analysis, scanning electron microscopy, thermogravimetry, and differential scanning calorimetry. Furthermore, the effects of varying concentrations of impregnated metal ions on water adsorption properties were explored. Interestingly, a significant enhancement in the water adsorption performance and heat storage capacity was observed. The energy storage density could reach 838.4 kJ·kg −1 , with a maximum water adsorption amount of 0.53 kgH 2 O·kg −1 . Overall, these findings demonstrate that incorporating CNT expansion and hygroscopic salt magnesium sulfate into the al-based metal–organic framework substantially improves the heat storage performance of the composite adsorption heat storage material. Such advancements hold promising implications for applications in solar thermal power generation systems.

The development of innovative multi-emission sensors for the rapid and accurate detection of contaminants is both vital and challenging. In this study, utilizing two rigid ligands (H 3 ICA and H 4 BTEC), a series of water-stable bimetallic organic frameworks (EuTb-MOFs) were synthesized. Luminescent investigations have revealed that EuTb-MOF-1 exhibits prominent multiple emission peaks, attributed to the distinctive fluorescence characteristics of Eu(III) and Tb(III) ions. Therefore, EuTb-MOF-1 efficiently recognized various metal ions and pharmaceutical compounds through 2D decoded maps. Fe 3+ and Pb 2+ exhibited significant quenching effects on the luminescence of EuTb-MOF-1, which were attributed to the internal filtering effect and the interaction between Lewis basic sites within EuTb-MOF-1 and Pb 2+ ions, respectively. Furthermore, EuTb-MOF-1 demonstrated high sensitivity to sulfonamide antibiotics, with detection limits of 0.037 μM for SMZ and 0.041 μM for SDZ, respectively. In addition, EuTb-MOF-1 was immobilized to prepare MOF-based test strips, enabling direct visual detection of sulfonamides as a portable sensor. With excellent water stability, multi-responsive recognition capabilities, and high sensitivity to specific analytes, EuTb-MOF-1 is a promising candidate for environmental contaminant detection in aquatic systems.

Phosphate plays a crucial role in various physiological and pathological processes; however, effective strategies for analyzing diverse phosphates and monitoring phosphate hydrolysis remain limited. Herein, we develop a metal–organic framework wrapped Cu nanoclusters-based (CuNCs@MOF) fluorescent sensor array for high-throughput discrimination of phosphates and real-time monitoring of their enzymatic hydrolysis. Leveraging the confinement effect of zinc-based MOFs, the encapsulated CuNCs exhibited reduced intramolecular vibration and rotation, resulting in enhanced luminescence performance. Due to the distinct affinities of various phosphates toward zinc ions, the sensor array generates differentiated fluorescence responses for seven phosphates, including adenosine triphosphate (ATP), cytidine triphosphate, uridine triphosphate, adenosine diphosphate, adenosine monophosphate, pyrophosphate (PPi), and inorganic phosphate. Subsequently, the fluorescence response signals are processed using the pattern recognition algorithm to generate the unique fingerprint spectra of each phosphate. We demonstrate that the sensor array can not only identify seven distinct phosphates at concentrations as low as 5 μM and effectively distinguish between their mixtures but also exhibit excellent anti-interference capability and enable dynamic monitoring of ATP and PPi hydrolysis. Notably, the sensor array achieved outstanding performance in complex real-world samples and cellular-level analyses, demonstrating 100% accuracy in blind sample identification. Overall, this work develops a strategy for high-throughput discrimination of phosphates and real-time monitoring of their enzymatic hydrolysis.

Tooth extraction often leads to significant alveolar bone resorption, posing a major clinical challenge that compromises subsequent prosthodontic rehabilitation. This impaired bone regenerative capacity is primarily attributed to excessive reactive oxygen species (ROS), insufficient angiogenesis, and inadequate osteoinductive stimulation within the socket, collectively delaying the healing process. To address this, we developed an injectable dual-network hydrogel system loaded with metal–organic framework (MOF) and osteogenic growth peptide (OGP) to promote the tooth extraction socket healing. The double-network hydrogel, composed of gelatin methacryloyl (GelMA) and oxidized dextran (ODex), forms a dynamic network through the Schiff base reaction between the amino groups of GelMA and the aldehyde groups of ODex, enabling injectability and adaptation to the irregular shape of the socket, while the second covalent network, formed by photo-cross-linking, enhances its mechanical properties. Besides, MOF decomposes to release magnesium ion (Mg2+) and gallic acid (GA) to eliminate excess ROS and promote endothelial cell differentiation, facilitating angiogenesis, while OGP is an efficient osteoinductive agent. In vitro studies demonstrate that the composite hydrogel system efficiently exerts antioxidant properties to eliminate ROS, promotes angiogenesis, and enhances osteogenesis. Moreover, in vivo trials show that the composite hydrogel facilitates angiogenesis and bone formation in the tooth extraction socket, ultimately promoting the bone repair process.

Triboelectric nanogenerators (TENGs) are widely employed in self-powered pressure sensing, yet devices based on a single triboelectric layer have approached their performance ceiling. Herein, a “double triboelectric layer” strategy is proposed to construct a flexible, self-powered, single-electrode pressure sensor. The charge-generation layer employs Co-MOF with high surface area and excellent conductivity, blended into Ecoflex to maximize triboelectric charge output, while the charge-trapping layer incorporates highly electronegative PVDF into Ecoflex to suppress interfacial charge neutralization and expedite charge transport. Benefiting from the biomimetic micro-textured surface created by sandpaper templating, the enhanced charge-storage density afforded by Co-MOF-doped generation layer, and the elevated charge-transfer efficiency introduced by the PVDF-doped trapping layer, the device based on a double triboelectric layer boosts peak voltage to 86 V, which is a 177 % increase compared with the single-layer device (31 V). It delivers an ultrahigh sensitivity of 11.17 V kPa⁻¹ over 0–6 kPa and maintains stable operation beyond 11,00 cycles. With fast response and long-term reliability, the sensor accurately captures human motions and wrist-pulse signals. This architecture pioneers a pathway toward high-performance, self-powered sensors tailored for next-generation wearable electronics.

The effective and rapid separation of oil–water emulsions at room temperature, particularly under harsh environmental conditions like acid–base fluctuations, high salinity, and the coexistence of surfactants, remains a significant challenge in oily wastewater treatment. To address this, a novel amphiphilic demulsifier, MOF-74@SiO 2 -GPTMS grafted ANP (MSG-ANP), was synthesized by first modifying MOF-74@SiO 2 (MS) with γ-glycidoxypropyltrimethoxysilane (GPTMS) to create epoxy-functionalized MSG particles, followed by grafting the non-ionic polyether C 12 –C 14 aliphatic polyethylene oxide polyoxypropylene (ANP) onto MSG. Bottle tests demonstrated that MSG-ANP achieved a high demulsification efficiency of 93% within 15 min for oil-in-water emulsions at room temperature. It exhibited excellent environmental tolerance, maintaining efficiencies of 89% at pH 3.0, 82% at pH 11.0, and 95% under high salinity (50,000 mg/L, pH 6.8). Furthermore, MSG-ANP effectively treated surfactant-stabilized emulsions, exceeding 96% efficiency against both cetyltrimethylammonium bromide and sodium dodecyl sulfate after 30 min, outperforming commercial demulsifiers SP-169 and AR-331 by factors of 1.2 and 1.6, respectively. This superior performance stems from synergistic hydrogen bonding (via hydroxyl, ether, ester, Fe-O, and Si-O groups) destabilizing the interfacial film and electrostatic neutralization of coalescing charged droplets. Consequently, MSG-ANP presents a promising solution for rapid, room-temperature demulsification across a wide pH range and under high-salinity conditions.

The thoughtful construction of highly efficient, tiered photocatalysts has become a focal point of interest. Herein, in this context, the step-scheme (S-scheme) AlBi-MOF/MgNiAl-LDH heterojunction is specifically engineered to facilitate the photocatalytic reduction of CO 2 . The CO 2 photocatalytic reduction experiments of three samples, AlBi-MOF, MgNiAl-LDH and AlBi-MOF/MgNiAl-LDH, were conducted for 5 h using triethanolamine as the sacrificial agent, the optimized sample demonstrates significantly enhanced CO 2 photoreduction efficiency compared to the control without treatment, i.e., AlBi-MOF and MgNiAl-LDH. The optimized AlBi-MOF/MgNiAl-LDH exhibited a CO 2 reduction rate of 86.84 μmol g −1 h −1 , which was 25.85 times higher than that of MgNiAl-LDH alone and 20.15 times higher than that of AlBi-MOF alone. The improved photocatalytic efficiency is mainly attributed to the decreased recombination of photogenerated charge carriers, facilitated by S-scheme heterojunction. Additionally, the large specific surface areas and abundant active sites also contribute to the improvement. Meanwhile, the S-scheme photocarrier transfer mechanism was verified by in situ X-ray photoelectron spectrum (XPS) and femtosecond transient absorption spectroscopy (fs-TA). This research outlines an effective methodological for advancing highly efficient heterojunction photocatalysts dedicated to the transformation of solar energy into fuel.

High water flux and dye rejection are crucial for effective textile wastewater treatment. In this study, novel two-dimensional (2D) metal-organic frameworks (MOFs) were synthesized and combined with one-dimensional (1D) halloysite nanotubes (HNTs) and polydopamine (PDA) to fabricate the thin-film nanocomposite (TFN) membranes. The surface morphology, chemical composition, and separation performance of resultant membranes were systematically characterized to illustrate their structure-property-performance relationships. Introducing hydrophilic 1D HNTs enhanced membrane hydrophilicity and bridged large gaps between the 2D MOF nanosheets. Under optimized conditions, the PDA-HNTs/MOFs membrane achieved a water permeance of 362.1 LMH·bar⁻¹ and 99.9 % rejection of Congo Red. PDA acted as a “bridge” linking HNTs and MOFs to the membrane substrate, thereby providing excellent antifouling performance and long-term stability. After 72 h of continuous operation, this membrane maintained a 99.1 % rejection of Congo Red, greatly surpassing both pure MOFs and HNTs/MOFs membranes. These findings highlight the superior filtration capabilities and promising potential of PDA-HNTs/MOFs membranes for dye wastewater treatment.

The integration of microscopic material designs and macroscopic structural layouts offers unlimited potential for developing advanced electromagnetic wave (EMW) absorbers. Herein, a pyrolysis-based strategy is reported for the hybridization of Ti 3 C 2 T x MXene nanosheets to achieve relaxation processes and high-density magnetic coupling at the nanoscale. The stratified structure of Ti 3 C 2 T x /Fe-MOF considerably amplifies the active contact region with electromagnetic radiation, thereby inducing numerous reflection/scattering phenomena. Through pyrolytic transformation, derived nanoparticles including Fe, C, Fe 3 O 4 , and TiO 2 establish continuous metal–carbon and carbon-oxide interfaces below 50 nm. Consequently, the heterogeneous interfaces formed between these components establish a harmonious electromagnetic coupling network, where interfacial polarization from numerous heterojunctions promotes charge accumulation and relaxation processes, converting electromagnetic energy into thermal energy. Remarkably, findings indicate that this composite material demonstrates a minimum reflection loss (RL min ) of −47.05 dB when the thickness reaches 1.8 mm. Additionally, this investigation broadens the spectrum of design strategies for premium microwave absorption materials through systematic interface engineering and thermally-controlled phase conversion.

Staphylococcus aureus , a prevalent foodborne pathogenic bacterium, poses a significant threat to human health. Herein, a dual-mode sensing method is proposed for detecting S. aureus in food using aptamer-modified Fe/Zr metal organic framework (Apt@Fe/Zr MOF). The Apt@Fe/Zr MOF was prepared through self-assembly of Fe/Zr MOF followed by surface modification with an aptamer. It exhibits peroxidase-like activity, catalyzing the 3,3′,5,5′-tetramethylbenzidine (TMB) chromogenic reaction. Meanwhile, Apt@Fe/Zr MOF demonstrates fluorescent characteristics, emitting a fluorescence signal at 428 nm upon excitation with light at 350 nm. Based on this feature, dual-mode sensing of S. aureus with comparable specificity and excellent anti-interference was achieved through the integration of colorimetry and fluorometry. The limits of detection (LOD) for both colorimetric and fluorometric analyses were 3.25 × 10 1 and 1.47 × 10 1 CFU mL −1 , respectively. Actual detection of food samples indicates that this method exhibits excellent reliability and accuracy, with recoveries ranging from 91.12 to 107.55% (colorimetry) and 94.40 to 109.47% (fluorometry). The results are highly consistent with those obtained from traditional culture-based methods. Therefore, it is evident that the dual-mode detection of S. aureus using Apt@Fe/Zr MOF offers a rapid and reliable method for ensuring food safety. Graphical
