Title: A Spiderweb-Like Metal-Organic Framework Multifunctional Foam
Processing metal-organic-frameworks (MOFs) into hierarchical macroscopic materials can greatly extend their practical applications. However, current strategies suffer from severe aggregation of MOFs and limited tuning of the hierarchical porous network. Here, we report a controlled strategy that can simultaneously tune the MOF loading, composition, spatial distribution, and confinement within various bio-originated macroscopic supports, as well as control the accessibility, robustness, and formability of the support itself. Our methodology enables the good dispersion of individual MOF nanoparticles on a spiderweb-like network within each macrovoid even at high loadings (up to 86 wt%), ensuring the foam pores are highly accessible for excellent adsorption and catalytic capacity. Additionally, this approach allows the direct pre-incorporation of other functional components into the framework. Our strategy provides a general toolbox for precise control over the properties of both the hierarchical support and MOF, opening new possibilities to construct tunable multi-scale porous platforms with desired functionalities.  more » « less

    Metal–organic frameworks (MOFs) are considered promising templates for the fabrication of nanostructured materials with high porosities and high surface areas, which are important parameters for enhanced performance in sensing applications. Here, a facile in situ synthetic strategy to construct MOF-derived porous CuO polyhedrons on carbon cloth (CC) is reported. Uniform Cu(OH) 2 nanorods are first synthesized on carbon cloth, followed by the conversion of Cu(OH) 2 nanorods into porous CuO polyhedrons via a copper-based MOF, Cu–BTC, as the intermediate species. When evaluated as a glucose sensing electrode, the as-fabricated CuO polyhedrons/CC composite exhibits a high sensitivity of 13 575 μA mM −1 cm −2 with a fast response time ( t 90 ) of 2.3 s and a low detection limit of 0.46 μM. This work exemplifies the rational fabrication of porous nanostructures on conductive substrates for enhanced performance in glucose detection.

    Despite great promise as next-generation high-capacity energy storage devices, lithium–sulfur batteries still face technical challenges in long-term cyclability. With their porous structures and facile synthesis, metal–organic frameworks (MOFs) are tunable platforms for understanding polysulfide redox and can serve as effective sulfur hosts for lithium–sulfur batteries. This feature article describes our design strategies to tailor MOF properties such as polysulfide affinity, ionic conductivity, and porosity for promoting active material utilization and charge transport efficiency. We also present engineering approaches for implementing MOF-based sulfur cathodes for lithium–sulfur batteries with high volumetric density and under low temperature operation. Our studies provide fundamental insights into sulfur–host interactions and polysulfide electrochemistry in the presence of porous matrices, inspiring future designs of advanced batteries.

    Abstract Electrochemical applications of metal organic frameworks (MOFs) are of considerable current interest. Due to the large surface area exposed to solution, MOFs are potentially useful electrode materials for sensing inner‐sphere analytes, such as reactive oxygen species. Herein, we electrodeposited copper benzene tricarboxylate MOF (HKUST‐1) into the cavity of an open carbon nanopipette (CNP) to produce a CNP‐MOF nanoelectrode. Unlike electronically conductive metal or carbon electrodes, the electrochemical response of CNP–MOFs relies on oxidation/reduction of Cu(I)/Cu(II) nodes in the porous nanostructure. Nevertheless, sigmoidal steady‐state voltammograms with a well‐defined plateau current have been recorded for simple redox mediators, for example, ferrocenemethanol. A linear calibration curve obtained for the hydrogen peroxide reduction suggests that CNP–MOFs can potentially be useful as nanosensors for peroxide.

    Recently, metal–organic framework (MOF)-based polymeric substrates show promising performance in many engineering and technology fields. However, a commonly known drawback of MOF/polymer composites is MOF crystal encapsulation and reduced surface area. This work reports a facile and gentle strategy to produce self-supported MOF predominant hollow fiber mats. A wide range of hollow MOFs including MIL-53(Al)–NH 2 , Al-PMOF, and ZIF-8 are successfully fabricated by our synthetic method. The synthetic strategy combines atomic layer deposition (ALD) of metal oxides onto polymer fibers and subsequent selective removal of polymer components followed by conversion of remaining hollow metal oxides into freestanding MOF predominant hollow fiber structures. The hollow MOFs show boosted surface area, superb porosity, and excellent pore accessibility, and exhibit a significantly improved performance in CO 2 adsorption (3.30 mmol g −1 ), CO 2 /N 2 separation selectivity (24.9 and 21.2 for 15/85 and 50/50 CO 2 /N 2 mixtures), and catalytic removal of HCHO (complete oxidation of 150 ppm within 60 min).

    Hydrogen sulfide (H 2 S) is an endogenous gasotransmitter with potential therapeutic value for treating a range of disorders, such as ischemia-reperfusion injury resulting from a myocardial infarction or stroke. However, the medicinal delivery of H 2 S is hindered by its corrosive and toxic nature. In addition, small molecule H 2 S donors often generate other reactive and sulfur-containing species upon H 2 S release, leading to unwanted side effects. Here, we demonstrate that H 2 S release from biocompatible porous solids, namely metal–organic frameworks (MOFs), is a promising alternative strategy for H 2 S delivery under physiologically relevant conditions. In particular, through gas adsorption measurements and density functional theory calculations we establish that H 2 S binds strongly and reversibly within the tetrahedral pockets of the fumaric acid-derived framework MOF-801 and the mesaconic acid-derived framework Zr-mes, as well as the new itaconic acid-derived framework CORN-MOF-2. These features make all three frameworks among the best materials identified to date for the capture, storage, and delivery of H 2 S. In addition, these frameworks are non-toxic to HeLa cells and capable of releasing H 2 S under aqueous conditions, as confirmed by fluorescence assays. Last, a cellular ischemia-reperfusion injury model using H9c2 rat cardiomyoblast cells corroborates that H 2 S-loaded MOF-801 is capable of mitigating hypoxia-reoxygenation injury, likely due to the release of H 2 S. Overall, our findings suggest that H 2 S-loaded MOFs represent a new family of easily-handled solid sources of H 2 S that merit further investigation as therapeutic agents. In addition, our findings add Zr-mes and CORN-MOF-2 to the growing lexicon of biocompatible MOFs suitable for drug delivery.
