Metal ferrite (MFe2O4) is a type of ceramic oxide with magnetoelectric properties. In this review, we have collected and analyzed the research trends MFe2O4 as heterogeneous catalyst in multicomponent reactions (MCRs). could activate specific groups reactants by increasing their electrophilicity acting Lewis acid capable accepting electrons to form covalent bonds. Using has been shown produce simple high yields, easy separate, more environmentally friendly. As reusable green catalyst, spinel stability, so it can be used repeatedly.

Inorganics, Год журнала: 2024, Номер 12(6), С. 143 - 143

Опубликована: Май 22, 2024

This work studies the synthesis, characterization, and application of CuFe2O4 nanoparticles for removal acid blue 113 malachite green dyes from aqueous media. Utilizing combustion procedure, were synthesized using two different fuels: L-alanine (CFA) L-valine (CFV). Besides, characterized through some tools, including Fourier transform infrared (FTIR), X-ray diffraction (XRD), energy-dispersive (EDX), field emission scanning electron microscope (FE-SEM). XRD analysis verified creation a cubic spinel structure without any contaminants, revealing average crystallite sizes 26.37 17.65 nm CFA CFV samples, respectively. The FTIR spectra exhibited peaks indicative metal-oxygen bond stretching, verifying presence formation. Elemental via EDX confirmed stoichiometric composition typical copper ferrite. In addition, FE-SEM displayed that samples are composed particles with spherical irregular shapes, measuring diameters 188.35 132.78 nm, maximum adsorption capabilities towards 281.69 297.62 mg/g, Also, products dye 280.11 294.99 Kinetic equilibrium revealed process onto followed pseudo-second-order model Langmuir isotherm. Thermodynamic indicated was physical, spontaneous, exothermic.

An electrochemical aptasensor has been developed to determine breast cancer biomarkers (CA 15-3). Aptamer chains were immobilized on the surface of electrode by g-C3N4/Fe3O4 nanoparticles, which increased conductivity and active area electrode. X-ray diffraction analysis (XRD), Fourier-transformed infrared spectroscopy (FTIR), transmission electron microscopy (TEM) measurements have carried out characterize nanomaterials. Cyclic voltammetry, square wave impedance used The results demonstrate that modified better selectivity for CA 15-3 compared other biological molecules. It a good response with detection limit 0.2 UmL-1 linear between 1 9 UmL-1. as label-free sensor in potassium ferrocyanide medium methylene blue-labeled phosphate buffer medium. This was successfully applied analyze serum diseased healthy individuals, corroborates its high potential biosensing applications, especially diagnosis cancer.
