Zinc ferrite (ZnFe2O4) nanoparticles were synthesized via the auto-combustion assisted sol-gel method of Zn2+ and Fe3+ ions (molar ratio 1:2) in ammonia solution. The prepared nanomagnetic catalyst was characterized by IR, XRD, SEM and ICP. The diameter of the ZnFe2O4 MNPs (63.7 nm) was determined by Debye-Scherre equation via their XRD pattern. Nanomagnetic ZnFe2O4 efficiently catalyzes oxidat...
در این پژوهش فعالیت فوتوکاتالیستی ZnO با باند گپ eV 2/3 و کامپوزیت آن با نیمههادی ZnFe2O4 با باند گپ eV 9/1 بررسی شده است. همچنین تاثیر افزایش درصد ZnFe2O4 به ZnO روی فعالیت فوتوکاتالیستی نانوکامپوزیت ZnO-ZnFe2O4 مورد بررسی قرار گرفته است. از روش میکروامولسیون معکوس به عنوان روشی جدید در سنتز نانوذرات استفاده شده و همچنین مقادیر ZnO-(10, 30, 50%) ZnFe2O4 از این نانوکامپوزیت برای بررسی سنتز شد...
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...
In the present work, the ZnFe2O4 nanoparticle has been successfully synthesized. The obtained sample was characterized by X-ray diffraction (XRD), emission scanning electron microscopy (FE-SEM) and its optical property was examined by UV-Vis spectrophotometer. FE-SEM revealed that the particle size of the ZnFe2O4 of about 47 nm was synthesized. The photocatalytic performance under UV-Vis and vi...
In this study, engine performance and emissions effects of ZnFe2O4 ZnCO3 nanoparticle additives have been investigated in a Diesel engine. The experiments carried out at 600 rpm different loads (250-380 Nm) 11670 cc heavy-duty Mixtures applied to diesel fuel as 100 ppm. Brake thermal efficiency, cylinder pressure, emission values tested for all mixtures. maximum efficiency D-ZnCO3-100 D-ZnFe2O4...
Natural Zn reserves might be exhausted in the following decades. Electric arc furnace (EAF) dust is an essential secondary resource. The recovery of from EAF a critical factor sustainable development industry and steelmaking industry. Efficient destruction ZnFe2O4 crystal structure separation Fe are key issues to recycle dust. Molten metal chlorides believed effective breaking ZnFe2O4. This wor...
Triple-shelled ZnFe2O4 hollow microspheres (ZFO) as anode materials for lithium ion battery are prepared through a one-pot hydrothermal reaction using the composite solution consisting of sucrose in water and metal ions in ethylene glycol (EG), followed by different calcination processes. The architectures of ZFO micro spheres are differently synthesized through a mutual cooperation of inward a...
The synthesis of ZnFe2O4 nanoparticles was performed using the solution combustion method with three types fuel, namely urea, glycine, and ethylenediamine tetra-acetic acid (EDTA) precursors (Zn(NO3)2.6H2O Fe(NO3)3.9H2O. process conducted in an open space at 300 °C for ± 1 h, resulting a brownish-black ZnFe2O4. Meanwhile, fuel type used affects physicochemical properties XRD analysis showed tha...
