In this work, a novel RuCo bimetallic supported on N-doped carbon support containing alumina was prepared by in-situ pyrolysis using MOF-303 as the support precursor (Ru 3 Co 1 @CN-Al 2 O 3 ), and it was applied to the efficient hydrodeoxygenation (HDO) of guaiacol under mild conditions (0.01 MPa H 2 , 200 °C, 3h), the yield of cyclohexanol reaches an impressive 83.12 %. In the absence of external hydrogen (2 MPa N 2 , 220 °C, 2 h), complete conversion of guaiacol was achieved, along with a remarkable 97.81 % selectivity towards cyclohexanol. The HDO of guaiacol under different atmospheres was further studied, and the possible mechanism was proposed. Characterization results indicated that the supported metals (Ru and Co) not only interacted with the N in the MOF-303 to enhance catalyst stability but also that the synergistic effect between Ru and Co was key to promoting the high yield of cyclohexanol through catalytic transfer hydrodeoxygenation (CTHDO) in isopropanol. Additionally, Ru 3 Co 1 @CN-Al 2 O 3 was also effective in achieving the HDO of macromolecular lignin. This study provides a feasible approach for the high value-added green transformation of lignin and its derivatives under mild conditions, highlighting the significant potential of MOFs for lignin valorization.

SnO 2 /MOF-303 nanocomposites were synthesized via a wet impregnation method. • SnO 2 nanoparticles were well-dispersed in the mesopores of SnO 2 /MOF-303 nanocomposites. • SnO 2 nanoparticles greatly enhanced the humidity sensitivity of SnO 2 /MOF-303 sensors. • The response/recovery times and humidity hysteresis of 16.7SnM sensor are favorable. • This improvement came from the synergistic effect between the proton and electron transport. Mesoporous MOF-303 was synthesized via a hydrothermal method using H 3 PDC and AlCl 3 as precursors. Subsequently, SnO 2 nanoparticles were incorporated into the micropores of MOF-303 through a wet impregnation process, yielding the SnO 2 /MOF-303 nanocomposite. The nitrogen atoms within the MOF-303 framework form strong coordination interactions with Sn 4+ , effectively anchoring the SnO 2 species within the micropores. This nano-confinement effect further promotes the formation of SnO 2 nanoparticles at low temperatures. Morphological and microstructural characterization confirmed that the SnO 2 nanoparticles were uniformly dispersed within the SnO 2 /MOF-303 nanocomposite and primarily located in the micropores. Humidity-sensing measurements demonstrated that the incorporation of SnO 2 nanoparticles significantly enhanced the humidity sensitivity of the SnO 2 /MOF-303 sensor at room temperature. Among the four sensors prepared in this study, the 16.7SnM sensor (with a nominal SnO 2 content of 16.7 wt% in the precursor solution) exhibited the highest humidity sensitivity, the fastest response and recovery times, the lowest hysteresis, and excellent long-term stability. This substantial improvement in humidity-sensing performance is attributed to the synergistic effect between proton and electron transport, arising from the increased oxygen vacancies introduced by the SnO 2 nanoparticles. The outstanding performance of the 16.7SnM sensor presents a promising strategy for the development of high-performance humidity sensors Download: Download high-res image (231KB) Download: Download full-size image

The search for triboelectric materials with cost-effective synthesis methods and easy integration into triboelectric nanogenerators (TENGs) is an intense area of research to explore their potential and achieve high output performance. The current article presents the use of metal–organic framework-303 (MOF-303) as a positive triboelectric material in developing TENGs and explores applications in road safety. MOF-303 films were directly grown on an aluminum sheet through a simple hydrothermal synthesis method, enabling easy integration into the TENG device. The positive triboelectric nature of MOF-303 is verified with standard tests. The resulting TENG, incorporating MOF-303 as the positive and fluorinated ethylene propylene (FEP) as the negative triboelectric films, delivers an open-circuit voltage of approximately 435 V, a short-circuit current of 85 μA, and a power density of 7.4 W/m2. Furthermore, the continuous operation of the digital watch and calculator is demonstrated with the help of an energy management circuit. The present research paves the way for exploring the possibilities of the direct synthesis of MOF films on conducting substrates and exploring their actual triboelectric potential. The proposed use of these self-powered indicators represents a significant advancement toward enhancing future road safety systems. The simplicity of the fabrication process, combined with the significant output of the device, suggests excellent potential for its use in self-powered applications.

Metal organic frameworks (MOFs) have emerged as promising candidates for atmospheric water harvesting due to their high porosity and tunable functionality. Among diverse MOFs, MOF-303 has demonstrated excellent water adsorption capacity, rapid desorption kinetics and structural stability. Nevertheless, its practical application is still limited by the time-consuming synthesis process and difficulties in morphological control. To overcome these challenges, a surfactant-mediated microwave-assisted strategy was proposed. Compared to conventional heating methods, microwave irradiation reduced the reaction duration from 24 h to 1 h with a 13% increase in product yield (from 76 % to 89 %). However, the accelerated nucleation under microwave irradiation resulted in smaller crystal dimensions (from 50 nm ± 10 nm to 35 nm ± 10 nm), therefore inducing severe particle agglomeration. To mitigate this morphological drawback, systematic investigations were conducted to evaluate the effects of surfactants’ species on crystal growth. Among the selected surfactants, poly(sodium- p -styrene sulfonate) (PSS) was identified as an effective morphology-directing agent, achieving uniform crystal sizes with improved monodispersity through preferential adsorption on specific crystallographic planes of the metal-organic framework. Subsequent optimization of synthetic conditions, including temperature (120−160 °C), reaction time (15 min−1 h), and surfactant concentration, yielded metal organic frameworks-303 (MOF-303) with a yield of 96.37%, with particle uniformity of (35 nm ± 10 nm) and predominantly blocky crystal morphology. Water adsorption measurements confirmed that the surfactant-modified MOF-303 retained comparable performance to the surfactant-free counterpart, with a maximum capacity (water/MOF) of 0.214 g·g −1 at 35% RH. This study establishes a scalable and tunable synthetic protocol for MOF-303, providing critical insights into microwave-accelerated crystal engineering.

Membrane technology has become one of the most effective methods for treating oily wastewater, which is harmful to the survival of ecosystems. However, separation membranes often suffer from serious fouling problems. Therefore, in this work, MOF-303 nanoparticles and attapulgites (APT) were loaded on the surface of polyvinylidene fluoride (PVDF) membrane based on the layer-by-layer self-assembly to construct MOF/APT/PEG composite membrane with excellent superhydrophilicity/underwater superoleophobicity, anti-fouling ability and outstanding emulsion separation performance, durability. It should be noted that a unique “absorption-storage” strategy for water molecules has been creatively adopted to realize anti-fouling and promote permeability. The separation efficiency of MOF/APT/PEG composite membrane was as high as 99.6 %, and permeability was above 1316 LMH/bar. Particularly, separation performance still remained stable after 10 cycles and 60 min of cross-flow separation. This study introduces a comprehensive and straightforward methodology for the development of membranes with anti-fouling properties aimed at the highly efficient treatment of oily wastewater.

To develop a high-performance humidity sensor, MOF-303, possessing both micro- and mesoporous structures, was selected as the host material for the sensor. SnO 2 nanoparticles were introduced via wet impregnation, and Cu(II) ions were anchored onto uncoordinated nitrogen sites of MOF-303, forming a ternary Cu(II)/SnO 2 /MOF-303 nanocomposites. The optimal sample denoted as 1-2CuSnM (with a molar ratio of Cu(II) to SnO 2 /MOF-303 of 1:2) achieved a response value of 116.98 over 11-98% RH, with response/recovery times of 16.2/6.3 s, low hysteresis (2.48% RH), and excellent 30-day stability (SD < 0.01) at room temperature. The synergy between Cu(II) and SnO 2 introduces abundant oxygen vacancies for water adsorption, while uncoordinated N sites enable proton hopping (Grotthuss mechanism) and Cu(II) dissociation enhances ionic conductivity, collectively reducing impedance. This ternary strategy is novel in combining protonic and ionic conduction pathways within a MOF framework, enabling a humidity sensor with wide range, fast response, and low hysteresis, key advancements over conventional materials.

Atmospheric water harvesting is a practical strategy that is achieved by removing materials from air moisture to relieve global water scarcity. Here we design a water-harvester (i.e., MOF-303/thiolated polymer composite (MTC)) by using a metal–organic framework (MOF-303) and thiolated chitosan (TC) skeleton. Intermolecular hydrogen bonding between TC and MOF-303 facilitates porous structures with enlarged air–polymer interfaces for long cycling life and high capacity at low relative humidity. Benefiting from synergetic effects on porosity and anchorage for accelerating the uptake-release of moisture, MTC exhibits a rapid water uptake capacity of 0.135 g/g in 60 min under 12.5 RH% and ultrafast water desorption kinetics of 0.003 g/g/min at 8.5 RH%, which is superior to the as-reported MOF-303 based adsorbents. At low heat (∼40 °C), the water desorption and collection rate, respectively, are 0.0195 and 0.0168 g/g/min within 210 min, showing ultrahigh harvesting efficiency. These results highlight the enormous potential as promising materials for solving the world’s water scarcity crisis. This study offers an insight into the design of AWH materials, which can be extended into applications in some realms, e.g., freshwater development for industry in arid areas, water engineering-related devices and systems, etc.

Efficient and economical capture and separation of sulfur hexafluoride (SF6) are critical for emissions mitigation and industrial reuse. Conventional distillation methods remain energy-intensive, prompting the need for cost-effective alternatives. Here, MOF-303, constructed from earth-abundant aluminum and low-cost linkers, features optimally sized pores (8.3 Å) that selectively adsorb SF6 (5.5 Å) over N2 (3.6 Å). This rational pore engineering enables MOF-303 to achieve benchmark SF6 capture (1.91 mmol g–1 at P < 0.1 bar) with exceptional selectivity (148), while its low regeneration energy (22.9 kJ mol–1) ensures practical cycling. Breakthrough experiments confirm robust performance under dynamic conditions. Computational studies reveal how pore geometry enables size-exclusive recognition. Compared to noble-metal adsorbents, MOF-303’s earth-abundant components reduce costs by >70%, offering a sustainable solution for industrial SF6 recovery.

The development of efficient and long-duration antimicrobial agents remains an important and challenging goal for public health safety. Current silver-containing antimicrobials commonly suffer from the limited silver (Ag) content or uncontrolled release of Ag + ions, leading to restricted bactericidal activity and duration. Herein, we report an example of chelating Ag(I) into a highly stable and scalable aluminum-based MOF (Ag + @MOF-303) for achieving highly efficient sterilization. Due to the edge-to-edge arrangement of pyrazole rings with a short N − N distance of 3.4 Å, Ag + ions can be precisely chelated into the MOF-303 framework with a controlled amount of 0.28 g Ag g MOF −1 . The resulting material Ag + @MOF-303 was thoroughly characterized by powder X-ray diffraction, scanning electron microscopy, and energy dispersive spectroscopy. Bactericidal activity experiments revealed that Ag + @MOF-303 can efficiently inhibit a wide range of bacteria, with a minimal inhibitory concentration of 31.25 μg mL −1 and a minimum bactericidal concentration of 62.5 μg mL −1 against the Gram-negative strain Escherichia coli , corresponding to silver content of 8.75 and 17.5 μg mL −1 , respectively. The controlled Ag + release from Ag + @MOF-303 was monitored to show a gradual release of 26.1 % of its total silver content over 7 days. Benefiting from its highly stable framework, this material after sterilization could be easily regenerated by the re-metalation of Ag + ions into MOF-303, indicating its unique reutilization and sustainability for sterilization applications.

The development of highly active catalysts and catalytic systems is crucial for the efficient valorization of lignin biomass. In this paper, a defective CoNi bimetallic MOF-303 catalyst was synthesized by adjusting the thermal reduction temperature and bimetallic ratio, demonstrating efficient catalytic performance in the aqueous-phase hydrodeoxygenation (HDO) of vanillin to produce 2-methoxy-4-methylphenol (MMP). Under mild conditions (200 °C, 2 h, 0.5 MPa H 2 ), the Co 2 Ni 1 /M 460 catalyst achieves complete conversion of vanillin with an MMP yield of 90.42 %. Additionally, the catalyst exhibited high activity in the aqueous-phase HDO of lignin and other lignin-derived/model compounds. Remarkably, facilitated the depolymerization of lignin into low-molecular-weight aromatic compounds, predominantly MMP, via secondary catalysis (8 h). Characterization analyses revealed that the high activity of Co 2 Ni 1 /M 460 stems not only from its defect-induced large pores, which enhance substrate adsorption and active site availability, but also from the synergistic effects between the CoNi alloy and the MOF-303 framework (Co-N interaction), promoting C=O group activation and efficient HDO. This work presents a viable strategy for designing sustainable and efficient lignin catalytic systems, highlighting the promising catalytic potential of MOF-303.

Atmospheric water harvesting is a promising solution to freshwater shortage because it is not limited by location. Metal–organic frameworks (MOFs) have attracted much attention for low-humidity applications due to their large surface areas and strong water adsorption capacities. In this study, the desorption efficiency of MOF-based adsorbents under solar heating was improved by adding efficient photothermal materials. MOF-303 was combined with Fe3O4, MWCNTs, and Ti3C2 by ball milling. Characterization analysis of the composite materials’ morphology, elemental distribution, crystal structure, and functional group changes demonstrated that the composite formation was successful. The results showed that compared to the original MOF-303, adding 10 wt % photothermal material greatly improved light absorption, leading to faster solar heating and quicker water desorption. However, the introduction of photothermal materials leads to a reduction in the effective adsorption sites within the composite materials, resulting in lower saturated water absorption capacities for all three composites compared to the original MOF-303. Among the three composite materials, Ti3C2/MOF-303 shows the best overall performance. Under 40% RH conditions, the material increased water vapor adsorption from 0 g/g to 0.382 g/g within 30 min. After 20 min of irradiation at 1 sun, the surface temperature of the material rapidly rose to 87.4 °C, reducing the remaining water content to 11.3%. Under the same conditions, the original MOF-303 had a water vapor adsorption of 0.42 g/g, a surface temperature of 59.8 °C after irradiation, and a remaining water content of about 31.7%. Taking 30% RH as an example, the Ti3C2/MOF-303 water vapor adsorption capacity is about 8.1% lower than that of the original MOF-303. During desorption at 85 °C, it takes approximately 20 min to achieve complete desorption, which is 20% shorter than that of the original MOF-303.

Adsorption-based atmospheric water harvesting (AWH) is a promising approach to address freshwater scarcity, particularly in arid regions. The performance of AWH largely depends on the adsorbent. Traditional adsorbents often suffer from low moisture uptake and high regeneration temperatures, while emerging adsorbents such as polymer gels and metal-organic frameworks (MOFs) also face challenges like complex synthesis procedures. Although MOFs can adsorb water vapor under low-humidity conditions, their practical application is limited due to their powdered form.Here, we propose a composite aerogel adsorbent, PPy-MOF-303@SA, synthesized via directional freezing, which uses sodium alginate aerogel as the matrix, MOF-303 as the hygroscopic component, and polypyrrole as the photothermal component. By loading MOF onto the aerogel, the limitations of powdered materials are overcome. The vertically aligned channels formed in the aerogel enhance adsorption kinetics, while polypyrrole improves the photothermal conversion capability.The composite adsorbent achieves a water uptake of 0.39 g/g at 25°C and 30% relative humidity, reaching equilibrium within 60 minutes. Under 1 kW•m⁻² solar irradiation, the surface temperature reaches 72.7°C, with a desorption ratio of 96.73%.
