Опубликована: Апрель 4, 2024

Four Co(II)-based metal–organic frameworks (MOFs) were constructed by a mixed ligand strategy under solvothermal conditions. The controllable modification of the bridging groups in secondary building units was realized changing anions MOFs 1–3. MOF 4 with 3D framework structure obtained regulating solvent ratio following synthesis process 3. Furthermore, 1–4 exhibited efficient photocatalytic activity for degradation malachite green (MG) dye without any photosensitizer or cocatalyst low-energy light source, decolorization MG all reached more than 96.0% within 60 min, and maximal to be 99.4% (MOF 4). recycling experiments showed that rate still higher 91% after 10 cycles. In as representation, explored systematically. possible mechanism catalytic discussed, which proved existence oxidation active factors (•O2–, •OH, h+). intermediates pathways investigated based on high-performance liquid chromatography tandem mass spectrometry. Additionally, also excellent methylene blue, methyl violet, rhodamine B, basic red 9.

Novel formulations of metal-organic frameworks for controlled drug delivery

Expert Opinion on Drug Delivery, Год журнала: 2022, Номер 19(10), С. 1183 - 1202

Опубликована: Апрель 15, 2022

Metal-organic frameworks (MOFs) are one of the typical coordination polymers which constructed by metal ions/clusters and multitopic organic ligands. Compared with traditional porous materials, MOFs have advantages significant porosity, large specific surface area, adjustable chemical composition, structure tailorability, these unique features make them a promising candidate for controlled drug delivery.This review aims to summarize recent advances in development delivery, particular, focusing on its ability deliver various drugs their release mechanism, as well vivo vitro biological evaluation. Moreover, future research directions clinical treatment also outlined.Although numbers been developed nanocarriers further improvements still needed advance application clinic. For example, circulation mechanism degradation process vivo, efficiency pharmacokinetics evaluation drugs. The present work main focus progress effective delivery examine some challenges applications.

In this work, a new bimetallic Na(I)-Zn(II) metal-organic framework (MOF), formulated as [Na2Zn3(btc)2(μ-HCOO)2(μ-H2O)8] n (1) (H3btc = benzene tricarboxylic acid), and its composite (ZnO@1) have been successfully synthesized using solvothermal mechanochemical solid grinding methods. 1 ZnO@1 were characterized by diffraction [single-crystal X-ray (XRD) powder XRD], spectroscopic (ultraviolet-visible diffuse reflectance spectroscopy Fourier transform infrared spectroscopy), microscopic (transmission electron microscopy), thermal (thermogravimetric analysis) The surface area porosity of determined Brunauer-Emmett-Teller analyzer. Single-crystal confirms that Na1 Zn2 octahedral coordination environments, whereas Zn1 has tetrahedral geometry. Topological simplification shows 3,6-connected kgd net. MOF is crystallized with slight exhibits good tendency toward the encapsulation zinc oxide nanoparticles (ZnO NPs). photocatalytic behaviors investigated over MB dye under sunlight illumination promising degradation efficiencies 93.69% for 97.53% in 80 min.

Enhanced Removal of Rhodamine b Dye from Aqueous Media via Adsorption on Facilely Synthesized Zinc Ferrite Nanoparticles

Inorganics, Год журнала: 2024, Номер 12(7), С. 191 - 191

Опубликована: Июль 12, 2024

This paper studies the synthesis, characterization, and application of ZnFe2O4 nanoparticles for removal rhodamine b dye from aqueous media. Utilizing combustion procedure, were synthesized using two different fuels: glutamine (SG) L-arginine (SA). In addition, characterized through various techniques, including Fourier transform infrared (FTIR), X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM), energy-dispersive (EDX), high resolution transmission (HR-TEM), Brunauer-Emmett-Teller (BET) surface area analysis. XRD analysis verified creation a cubic spinel structure without any contaminants, revealing average crystallite sizes 43.72 29.38 nm SG SA samples, respectively. The FTIR spectra exhibited peaks indicative metal-oxygen bond stretching, verifying presence formation. Elemental via EDX confirmed stoichiometric composition typical zinc ferrite. FE-SEM imaging displayed that samples are composed particles with irregular spherical shapes, measuring diameters 135.11 59.89 nm, Furthermore, BET is 60 85 m2/g, maximum adsorption capacity sample (409.84 mg/g) towards was higher than (279.33 mg/g), which ascribed to its larger porosity. Kinetic equilibrium revealed process onto followed Langmuir isotherm pseudo-second-order model. Thermodynamic indicated spontaneous, exothermic, physical. study concludes (SA) exhibit enhanced efficiency due their smaller size, increased area, porosity compared those (SG). optimum conditions found be at pH 10, contact time 70 min, temperature 298 K. These findings underscore potential L-arginine-synthesized effective sustainable environmental cleanup applications.
