Benzene Oxidation in Air by an Amine-Functionalized Metal-Organic Framework-Derived Carbon- and Nitrogen-Loaded Zirconium Dioxide-Supported Platinum Catalyst.

To learn more about the behavior of amine (NH2)-functionalized metal-organic framework (MOF)-derived noble metal catalysts in the removal of aromatic volatile organic compounds in air, benzene oxidation at low temperatures has been investigated using 0.2-, 0.8-, and 1.5%-platinum (Pt)/Universitetet i Oslo (UiO)-66-NH2. The benzene conversion (XB) of x%-Pt/UiO-66-NH2-R under dry conditions (175 °C) was 23% (x = 0.2%) < 52% (x = 0.8%) < 100% (x = 1.5%): 'R' suffix denotes reduction pretreatment using a hydrogen (10 vol %) and nitrogen mixture at 300 °C for the generation of metallic Pt (Pt0) sites and simultaneous partial MOF decomposition into carbon- and nitrogen-loaded zirconium dioxide. The prominent role of reduction pretreatment was apparent in benzene oxidation as 1.5%-Pt/UiO-66-NH2 did not exhibit catalytic activity below 175 °C (dry condition). The promotional role of moisture in benzene oxidation by 1.5%-Pt/UiO-66-NH2-R was evident with a rise in the steady-state reaction rate (r) at 110 °C (21 kPa molecular oxygen (O2)) from 1.3 × 10-3 to 5.0 × 10-3 μmol g-1 s-1 as the water (H2O) partial pressure increased from 0 to 1.88 kPa. In contrast, the activity was lowered with increasing RH due to catalyst poisoning by excess moisture (r (110 °C) of 6.6 × 10-04 μmol g-1 s-1 at 2.83 kPa H2O (21 kPa O2)). Kinetic modeling suggests that XB proceeds through the Langmuir-Hinshelwood mechanism on the Pt/UiO-66-NH2-R surface (dissociative O2 chemisorption and the involvement of two oxygen species in benzene oxidation). According to the density functional theory simulation, the carbon and nitrogen impurities are to make the first XB step (i.e., hydrogen migration from the benzene molecule to the substrate) energetically favorable. The second hydrogen atom from the benzene molecule is also extracted effectively, while the oxygen derived from O2 facilitates further XB. The Pt0 sites dissociate the O2 and H2O molecules, while the product of the latter, i.e., free hydrogen and hydroxyl, makes the subsequent XB steps energetically favorable.

Rational Design of Coordination Polymers Composited Hollow Multishelled Structures for Drug Delivery.

Multifunctional drug delivery systems (DDS) are in high demand for effectively targeting specific cells, necessitating excellent biocompatibility, precise release mechanisms, and sustained release capabilities. The hollow multishelled structure (HoMS) presents a promising solution, integrating structural and compositional design for efficient DDS development amidst complex cellular environments. Herein, starting from a Fe-based metal-organic framework (MOF), amorphous coordination polymers (CP) composited HoMS with controlled shell numbers are fabricated by balancing the rate of MOF decomposition and shell formation. Fe-CP HoMS loaded with DOX is utilized for synergistic chemotherapy and chemodynamic therapy, offering excellent responsive drug release capability (excellent pH-triggered drug release 82% within 72h at pH 5.0 solution with doxorubicin (DOX) loading capacity of 284mg g-1). In addition to its potent chemotherapy attributes, Fe-CP-HoMS possesses chemodynamic therapy potential by continuously catalyzing H2O2 to generate ·OH species within cancer cells, thus effectively inhibiting cancer cell proliferation. DOX@3S-Fe-CP-HoMS, at a concentration of 12.5µg mL-1, demonstrates significant inhibitory effects on cancer cells while maintaining minimal cytotoxicity toward normal cells. It is envisioned that CP-HoMS could serve as an effective and biocompatible platform for the advancement of intelligent drug delivery systems in the realm of cancer therapy.

Laser-Assisted Design of MOF-Derivative Platforms from Nano- to Centimeter Scales for Photonic and Catalytic Applications.

Laser conversion of metal-organic frameworks (MOFs) has recently emerged as a fast and low-energy consumptive approach to create scalable MOF derivatives for catalysis, energy, and optics. However, due to the virtually unlimited MOF structures and tunable laser parameters, the results of their interaction are unpredictable and poorly controlled. Here, we experimentally base a general approach to create nano- to centimeter-scale MOF derivatives with the desired nonlinear optical and catalytic properties. Five three- and two-dimensional MOFs, differing in chemical composition, topology, and thermal resistance, have been selected as precursors. Tuning the laser parameters (i.e., pulse duration from fs to ns and repetition rate from kHz to MHz), we switch between ultrafast nonthermal destruction and thermal decomposition of MOFs. We have established that regardless of the chemical composition and MOF topology, the tuning of the laser parameters allows obtaining a series of structurally different derivatives, and the transition from femtosecond to nanosecond laser regimes ensures the scaling of the derivatives from nano- to centimeter scales. Herein, the thermal resistance of MOFs affects the structure and chemical composition of the resulting derivatives. Finally, we outline the "laser parameters versus MOF structure" space, in which one can create the desired and scalable platforms with nonlinear optical properties from photoluminescence to light control and enhanced catalytic activity.

Preparation of ZrC embedded carbon rods via thermal decomposition of metal organic frameworks

Synthesis of uniform, spherical ZrC is difficult and generally not cost-effective, as is the case for most ultra-high temperature ceramics. High aspect ratio particles for reinforcement of ceramic composites are even more difficult to synthesize. Metal organic frameworks (MOF) are crystalline coordination polymers composed of multidentate organic linkers bridging metal nodes to form porous structures. Thermal decomposition of MOFs presents a new and cost-effective route to synthesis of ZrC. In this study, heat treatment at 2000 °C of MOF PCN-222 produces zirconium carbide (ZrC) within a highly anisotropic particle. The resulting rod-shaped, glass-like carbon matrix embedded with ZrC crystals is described. These rods have potential as reinforcements for high temperature applications and as a synthetic route for ultra-high temperature ceramics with unique morphologies.

Reticular Coordination Induced Interfacial Interstitial Carbon Atoms on Ni Nanocatalysts for Highly Selective Hydrogenation of Bio-Based Furfural under Facile Conditions.

A rational design of transition metal catalysts to achieve selective hydrogenation of furfural (FFR) to tetrahydrofurfuryl alcohol (THFA) under facile conditions is a promising option. In this work, a series of Ni catalysts were synthesized by controlled thermal treatment of Ni-based metal-organic frameworks (MOFs), with the purpose of modulating the interface of nickel nanoparticles by the reticular coordination in MOF precursors. The catalytic performance indicates that Ni/C catalyst obtained at 400 °C exhibits efficient conversion of FFR (>99%) and high selectivity to THFA (96.1%), under facile conditions (80 °C, 3 MPa H2, 4.0 h). The decomposition of MOF at low temperatures results in highly dispersed Ni0 particles and interfacial charge transfer from metal to interstitial carbon atoms induced by coordination in MOF. The electron-deficient Ni species on the Ni surface results in an electropositive surface of Ni nanoparticles in Ni/C-400, which ameliorates furfural adsorption and enhances the hydrogen heterolysis process, finally achieving facile hydrogenation of FFR to THFA.

Chemical-triggered artificial cell based on metal-organic framework

An artificial cell based on an inducible cell-free expression system and metal–organic frameworks (MOFs), which can be triggered by chemical signals, was proposed in this study. The DNA expression templates were spatiotemporally encapsulated in MOF nanoparticles by co-precipitation and then wrapped in bio-mimicking liposomes. The signal of acidic pH or glucose induced the decomposition of MOFs, exposing the DNAs to start the cell-free expression to produce desired biopharmaceutical proteins. Therefore, the transcription and translation process could be controlled by simple chemical signals. This study investigated an unexplored topic of using MOFs in the construction of artificial cells, which could open new possibilities for future synthetic biology studies and therapeutic applications.

Thermal decomposition kinetics of M−BTC (M = Cu, Co, Zn, and Ce) and M−BTC/Pt composites under oxidative and reductive environments

Metal-organic frameworks (MOFs) have been utilized as an important precursor/template to prepare diverse metal or metal oxide nanomaterials. Herein, we studied the thermal decomposition behaviors of M−BTC (M = Cu, Co, Zn, and Ce; BTC = benzene-1, 3, 5-tricarboxylate) and the Pt-supported M−BTC nanocomposites (M−BTC/Pt) in different atmospheres by using thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS), in-situ X-ray diffractometer (in-situ XRD), and in-situ diffuse reflectance infrared Fourier transform spectroscopy (in-situ DRIFTS). The results indicated that the presence of Pt promoted the decomposition of the Cu-BTC, Co-BTC, and Zn-BTC under air atmosphere with lower activation energies. For instance, the Ea values of the decomposition process of Cu-BTC and Cu-BTC/Pt were 231 and 133 kJ/mol, respectively, which can be attributed to the enhanced ligand-to-metal charge transfer effect and higher oxygen adsorption capacity after the immobilization of Pt. However, the thermal decomposition of Ce-BTC showed a different trend with a larger Ea value in the presence of Pt (167 vs 105 kJ/mol). In-situ DRIFTS showed that the introduction of Pt would change the thermal decomposition modes of MOFs by the strong hydrogen overflow effect. However, the improved thermostability of Cu-BTC, Co-BTC, and Zn-BTC in the hydrogen atmosphere is owing to the hydrogenation of the carboxylate on the organic linkers. For instance, the Ea values of the decomposition process of Co-BTC and Co-BTC/Pt were 197 and 237 kJ/mol, respectively. Such findings could provide reference and guidance for further understanding of the effects of metal nanoparticles on the thermal decomposition of MOFs for controlling the physicochemical properties of the MOF-derived metal oxide nanomaterials.

Activatable autophagy inhibition-primed chemodynamic therapy via targeted sandwich-like two-dimensional nanosheets

• MOF-containing sandwich-like 2D nanosheets were constructed via a mild method. • The targeted nanosheets showed the activatable drug release and OH generation. • The nanosheets possessed an effective cellular uptake and tumor enrichment. • The autophagy inhibition could promote the ROS-involved chemodynamic activity. The ingenious construction of transition metal-containing nanomaterials holds great potential for desired chemodynamic therapy (CDT). Herein, Cu 2+ -based porous metal–organic frameworks (MOFs) were laterally grown on the substrate of ultrathin sSiO 2 nanosheets (NSs) for high-efficiency chloroquine (CQ) loading, which was then modified by CD44-targeted hyaluronic acid (HA) to develop targeted sandwich-like two-dimensional (2D) NSs (HA-CQ/HT@sSiO 2 NSs) for activatable autophagy inhibition-primed CDT. Specifically, the obtained HA-CQ/HT@sSiO 2 NSs initiated the reduction of Cu 2+ to Cu + by depleting overexpressed glutathione (GSH), which concomitantly induced the decomposition of MOFs for controllable cargo unloading. The formed Cu + then exerted Fenton-like catalyzing activity to generate detrimental hydroxyl radicals ( OH) for ROS-involved CDT. Meanwhile, the released CQ was utilized to inhibit autophagy via blocking autolysosomes formation and degradation, thereby turning off self-protection pathway of oxidative stress for harvesting autophagy inhibition-primed chemodynamic activity. Particularly, HA-CQ/HT@sSiO 2 NSs could effectively accumulate at tumor site and be rapidly internalized into tumor cells benefiting from unique sheet-like morphology and CD44-targeting specificity. Both in vitro and in vivo results confirmed the potent autophagy inhibition-primed CDT effect, suggesting the activatable targeted sandwich-like 2D NSs may be referential to the creative design of therapy regimen.

Glycerol Hydrogenolysis to 1,2-Propanediol over Novel Cu/ZrO2 Catalysts

Glycerol is the main by-product of biodiesel production; its upgrading to more valuable products is a demanding issue. Hydrogenolysis to 1,2-propanediol is one of the most interesting processes among the possible upgrading routes. In this study, we propose novel copper/zirconia catalysts prepared by advanced preparation methods, including copper deposition via metal–organic framework (MOF) and support preparation via the sol–gel route. The catalysts were characterized by N2 physisorption, X-ray diffraction, Scanning Electron Microscopy, H2-TPR and NH3-TPD analyses and tested in a commercial batch reactor. The catalyst prepared by copper deposition via MOF decomposition onto commercial zirconia showed the best catalytic performance, reaching 75% yield. The improved catalytic performance was assigned to a proper combination of redox and acid properties. In particular, a non-negligible fraction of cuprous oxide and of weak acid sites seems fundamental to preferentially activate the selective pathway. In particular, these features avoid the overhydrogenolysis of 1,2-propanediol to 1-propanol and enhance glycerol dehydration to hydroxyacetone and the successive hydrogenation of hydroxyacetone to 1,2-propanediol.

Development of an innovative nitrite sensing platform based on the construction of carbon-layer-coated In2O3 porous tubes

Excessive uptake of nitrite has been proven to be harmful for human health and ecological systems, so it is vital to develop a reliable methodology for nitrite analysis. In this work, we have synthesized innovative carbon-layer-coated In2O3 porous tubes (C@In2O3 PTs) to electrochemically detect nitrite in industrial wastewater samples. C@In2O3 PTs were prepared through the thermal decomposition of metal organic frameworks (MOFs, MIL-68-In) based on the two-step synthetic processes. The obtained C@In2O3 PTs displayed obviously increased catalytic activity to the electrochemical oxidation of nitrite, which benefited from the enhanced surface area and electron transfer based on the porous and hollow structure, and the maximized synergistic effect due to the intimate contact between In2O3 core and carbon layer. Thus, the sensitive determination of nitrite with a detection limit of 0.08 μM was realized, which was promising for sensitive determination of nitrite in the environmental analysis and food industry.

MOF‐derived nickel−cobalt bimetal oxide nanostructures as a cooperative catalyst for the reduction of 4‐nitrophenol

AbstractBACKGROUND4‐Nitrophenol, as a representative hazardous contaminant, may pose potential risks to the environment in the process of production, storage, and use. Catalytic hydrogenation reduction offers a promising route to the removal of 4‐nitrophenol by its transformation into the less toxic and biodegradable 4‐aminophenol. In this work, nickel−cobalt bimetal oxide nanostructures were fabricated by the thermal decomposition of metal organic frameworks and cooperatively utilized for the catalytic reduction of 4‐nitrophenol.RESULTSThe as‐fabricated oxide catalysts were characterized and analyzed with several physicochemical measurements, including X‐ray diffraction, scanning electron microscopy, transmission electron microscopy, X‐ray photoelectron spectroscopy, thermogravimetry, Fourier‐transform infrared spectroscopy, Raman spectroscopy, nitrogen adsorption, and electrochemical impedance spectroscopy. The catalytic reduction of 4‐nitrophenol was conducted in the presence of the as‐prepared oxide nanostructures with varying Ni/Co ratios to evaluate their catalytic activity. The optimal catalyst (Ni–Co–O) delivered the activity parameter of k’app = 12.0 min−1 mg−1, which was higher than either NiO (2.4 min−1 mg−1) or Co3O4 (3.6 min−1 mg−1). Moreover, the induction time of the 4‐nitrophenol reduction was significantly reduced by using the bimetal oxide catalyst. Based on the surface and electrochemistry analyses, the enhancement of catalytic activity for the Ni–Co bimetal oxide nanostructures was discussed.CONCLUSIONThe above results indicated that the cooperation of nickel with cobalt into bimetal oxide nanostructures exhibited an enhanced catalytic activity, which not only promoted the conversion rate of 4‐nitrophenol, but also shortened the reduction induction period.

Heterostructured g-CN/TiO2 Photocatalysts Prepared by Thermolysis of g-CN/MIL-125(Ti) Composites for Efficient Pollutant Degradation and Hydrogen Production.

Photocatalysts composed of graphitic carbon nitride (g-CN) and TiO2 were efficiently prepared by thermolysis of the MIL-125(Ti) metal organic framework deposited on g-CN. The heterojunction between the 12 nm-sized TiO2 nanoparticles and g-CN was well established and the highest photocatalytic activity was observed for the g-CN/TiO2 (3:1) material. The g-CN/TiO2 (3:1) composite exhibits high visible light performances both for the degradation of pollutants like the Orange II dye or tetracycline but also for the production of hydrogen (hydrogen evolution rate (HER) up to 1330 μmolh−1g−1 and apparent quantum yield of 0.22% using NiS as a cocatalyst). The improved visible light performances originate from the high specific surface area of the photocatalyst (86 m2g−1) and from the efficient charge carriers separation as demonstrated by photoluminescence, photocurrent measurements, and electrochemical impedance spectroscopy. The synthetic process developed in this work is based on the thermal decomposition of metal organic framework deposited on a graphitic material and holds huge promise for the preparation of porous heterostructured photocatalysts.

Hard X-ray-based techniques for structural investigations of CO2 methanation catalysts prepared by MOF decomposition.

Thermal decomposition of metal-organic framework (MOF) precursors is a recent method to create well-dispersed metal centers within active catalyst materials with enhanced stability, as required for dynamic operation conditions in light of challenges caused by the renewable energy supply. Here, we use a hard X-ray-based toolbox of pair distribution function (PDF) and X-ray absorption spectroscopy (XAS) analysis combined with X-ray diffraction and catalytic activity tests to investigate structure-activity correlations of methanation catalysts obtained by thermal decomposition of a Ni(BDC)(PNO) MOF precursor. Increasing the decomposition temperature from 350 to 500 °C resulted in Nifcc nanoparticles with increasing particle sizes, alongside a decrease in Ni2+ species and strain-induced peak broadening. For lower temperatures and inert atmosphere, Ni3C and NiO phases co-existed. A graphitic shell stabilized the Ni particles. Compared to an inert atmosphere, reducing conditions led to larger particles and a faster decomposition of the MOF precursor. Catalytic studies revealed that the decomposition at an intermediate temperature of 375 °C in 5% H2/He is the best set of parameters to obtain high specific surface areas while maintaining particle sizes that feature many active Ni centers for the formation of CH4.

Enhanced Drug Delivery by Dissolution of Amorphous Drug Encapsulated in a Water Unstable Metal–Organic Framework (MOF)

AbstractEncapsulating a drug molecule into a water‐reactive metal–organic framework (MOF) leads to amorphous drug confined within the nanoscale pores. Rapid release of drug occurs upon hydrolytic decomposition of MOF in dissolution media. Application to improve dissolution and solubility for the hydrophobic small drug molecules curcumin, sulindac, and triamterene is demonstrated. The drug@MOF composites exhibit significantly enhanced dissolution and achieves high supersaturation in simulated gastric and/or phosphate buffer saline media. This combination strategy where MOF inhibits crystallization of the amorphous phase and then releases drug upon MOF irreversible structural collapse represents a novel and generalizable approach for drug delivery of poorly soluble compounds while overcoming the traditional weakness of amorphous drug delivery: physical instability of the amorphous form.

Highly stable reduced graphene oxide-encapsulated Ce-MOF composite as sensing material for electrochemically detecting dichlorophen

Metal–organic frameworks (MOFs) as porous materials have been widely used in electrochemical sensing field. Unfortunately, their low electrical conductivity and poor stability in the aqueous solution limit their application. To overcome these shortcomings, in this study, a novel reduced graphene oxide-encapsulated Ce-MOF (RGO@Ce-MOF) composite was synthesized by using a simple and green method. Ce-MOF and GO were firstly casted onto glassy carbon electrode, respectively, and then GO was reduced to RGO through electrochemical reduction strategy. The proposed encapsulated structure of RGO@Ce-MOF effectively improved the stability of Ce-MOF by preventing decomposition of MOF in solution. The combination of RGO and Ce-MOF can also significantly promote the conductivity of composite. Then, the obtained RGO@Ce-MOF composite was utilized as electrode material for the detection of dichlorophen (Dcp), a halogenated phenolic intermediate for synthesis of pesticide. The electrochemical properties of the proposed sensor were investigated by electrochemical techniques in detail. Benefiting from the synergy between Ce-MOF and RGO, the RGO@Ce-MOF can be used to detect Dcp with a wide linear range from 0.02 μM to 10 μM and a low detection limit of 0.007 μM (S/N = 3). Furthermore, the RGO@Ce-MOF electrode showed acceptable reproducibility and good selectivity. This method was applied to detect Dcp in the real samples with satisfying results.

Highly stable nitrogen-doped carbon nanotubes derived from carbon dots and metal-organic frameworks toward excellent efficient electrocatalyst for oxygen reduction reaction

A highly efficient nitrogen-doped carbon nanotubes (N-CNTs) electrocatalyst derived from nitrogen-doped carbon dots (N-Cdots) and metal-organic frameworks (MOFs) for oxygen reduction reaction (ORR) was demonstrated successfully for the first time. The N-Cdots with plenty of hydroxyl and amine groups can favor the formation of N-CNTs through the catalytic decomposition of MOFs in a lower temperature. On the other hand, the N-Cdots serve as inducers of the graphitic structure and supply extra nitrogen, extending a potential electrocatalytic activity of N-CNTs. Results show that the N-CNTs provided an excellent ORR electrocatalytic performance, yielding a positive onset potential of 0.88 V vs. RHE and a high kinetic current density of up to 5.58 mA cm−2 at 0.2 V. In addition, the slope of N-CNTs being ∼81 mV/dec can be found to be much lower than that of the Pt/C catalyst (∼132 mV/dec). These superior performances are attributed to defects in the graphitic crystal structure and the synergistic coupling effects of N-Cdots and N-CNTs. In addition, a slight loss in activity for the N-CNTs catalyst can be found whereas the Pt/C catalyst decreases nearly 45% of its initial activity, which exhibit highly catalytic durability and tolerance to methanol in an alkaline media.

Dielectric and ferroelectric properties of LaFeO3 particles derived from metal organic frameworks precursor

As one of the few single-phase multiferroic materials with both antiferromagnetic and ferroelectric properties, LaFeO3 has attracted much attention, especially film and ceramic. In this work, LaFeO3 particles were prepared by thermal decomposition of Metal Organic Frameworks (MOFs) precursor La[Fe(CN)6]·5H2O, and the dielectric and ferroelectric properties of particles were studied for the first time. The effect of annealing temperature and time on the dielectric and ferroelectric performance were investigated in detail. The results indicate that the LaFeO3 particles annealed at 600 °C for 5 h achieve dielectric constant of 201, remnant polarization 2Pr of 0.064 μC/cm2 with coercive electric field 2Ec of 39.16 kV/cm, higher than those of other annealing time. In addition, the LaFeO3 particles annealed at 700 °C for 3 h exhibit dielectric constant of 178 and remnant polarization 2Pr of 0.072 μC/cm2 which are higher compared with other annealing temperatures. Our results provide useful information to study LaFeO3 particles.

Metal organic frameworks-derived sensing material of SnO2/NiO composites for detection of triethylamine

The SnO2/NiO composites were synthesized by hydrothermal followed by calcination using metal-organic framework (MOF) consisting of the ligand of p-benzene-dicarboxylic acid (PTA) and the Sn and Ni center ions as sacrificial templates. The structure and morphology of Sn/Ni-based MOF and SnO2/NiO composites were characterized by XRD, SEM, TEM, FT-IR, TG, XPS and Brunauer-Emmett-Teller analysis. Sensing experiments reveal that the SnO2/NiO composite with the molar ratio of 9:1 not only exhibits the highest response of 14.03 that is 3 times higher than pristine SnO2 to triethylamine at 70 °C, but also shows good selectivity. Such excellent performance is attributed to the MOF-driven strategy and the formation of p-n heterojunctions, because the metal ions can be highly dispersed and separated in the MOFs and can prevent the metal ions aggregation during the MOF decomposition process. The work is a novel route for synthesis of gas sensing material.

Design of Porous/Hollow Structured Ceria by Partial Thermal Decomposition of Ce-MOF and Selective Etching.

Metal-organic frameworks (MOFs) have been widely used to prepare corresponding porous metal oxides via thermal treatment. However, high temperature treatment always leads to obtained metal oxides with a large crystallite size, thus decreasing their specific surface area. Different from the conventional complete thermal decomposition of MOFs, herein, using Ce-MOF as a demonstration, we choose partial thermal decomposition of MOF, followed by selective etching to prepare porous/hollow structured ceria because of the poor stability of Ce-MOF under acidic conditions. Compared with the ceria derived from complete thermal decomposition of Ce-MOF, the as-prepared ceria is demonstrated to be a good support for copper oxide species during the CO oxidation catalytic reaction. Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), and hydrogen temperature-programmed reduction (H2-TPR) analysis revealed that the as-prepared ceria is favorable for strengthening the interaction between the ceria and loaded copper oxide species. This work is expected to open a new, simple avenue for the synthesis of metal oxides from MOFs via partial thermal decomposition.
