A new octahedral ZnO/ZnFe2O4 heterostructure has been fabricated through a facile surfactant-free solvothermal method followed by thermal treatment. It exhibits a record-high adsorption capacity (up to 4983.0 mg·g(-1)) of malachite green (MG), which is a potentially harmful dye in prevalence and should be removed from wastewater and other aqueous solutions before discharging into the environmen...

ZnFe2O4 nanocomposites have been prepared by a simple co‐precipitation method. The prepared samples were characterized by Scanning Electron Microscopy (SEM), Powder X‐ray Diffraction (XRD), Energy Disperse X‐ray Analysis (EDX), Transmission electron microscopy (TEM) and UV‐visible absorption spectral techniques. Conductivity measurements show a transition from ferrimagnetism to...

The purpose of the present study was to introduce a newly designed approach for determi­nation glutathione using modified carbon paste electrode with ZnFe2O4 nanoparticles, ionic liquid (1-butyl-3-methylimidazolium hexafluorophosphate) and ethyl 2-(4-ferrocenyl-[1,2,3]triazol-1-yl)acetate (EFTA/ZFO/IL/CPE). According results from electro­chemical experiments, oxidation current on surface increm...

Abstract Polyvinylidene fluoride (PVDF) polymer is considered as an encouraging piezoelectric material whose optical properties need to be enhanced. Zinc ferrite excellent photoelectric material, in the present work it was doped separately by (cobalt and copper) ferrite. Co-ZnFe 2 O 4 Cu-ZnFe nanoparticles were synthesized using auto-combustion method characterized XRD, FTIR, FESEM HRTEM. The c...

ZnFe2O4 mixed spinel ferrite nanoparticles obtained through a citrate-nitrate combustion method. Ignited products calcined at different temperatures in 600-900ºC range and effect of calcination treatment temperature investigated. Final Products characterized by X-ray Diffraction (XRD), Fourier-Transform Infrared spectroscopy (FTIR), and Field Emission Scanning Electron Microscopy (FESEM). The a...

Widespread overuse and misuse of antibiotics has led to unintended consequences, it is necessary find effective ways remove antibiotics. In this study, a visible-light-response photocatalyst zinc ferrite (ZnFe2O4) was synthesized via hydrothermal method. Meanwhile, the X-ray diffraction, Brunauer–Emmett–Teller, scanning electron microscope, photoelectron spectroscopy, Fourier transform infrared...

Density functional theory (DFT) calculations have been performed on A(2+)B2(3+)O4(2-) (where A(2+) = Fe, Ni or Zn, and B(3+) = Fe or Cr) spinel oxides in order to determine some of their thermodynamic properties. Mixing energies were calculated for Fe3O4-NiFe2O4, Fe3O4-ZnFe2O4, Fe3O4-FeCr2O4, NiFe2O4-ZnFe2O4, NiFe2O4-NiCr2O4, FeCr2O4-NiCr2O4, FeCr2O4-ZnCr2O4 and ZnCr2O4-ZnFe2O4 pseudo-binaries ...
