Zinc ferrite nanoparticles have wide range of the applications in field Electronics, Optoelectronics, Magnetics, Solar cell, Photocatalysts. With Al doping we modify their structural, magnetic and electrical properties zinc (ZnFe2O4). In present studies, were prepared by sol gel method using glycine as combustion agent. The effects concentration on morphological, optical, ferrites studied. x-ra...

In this study, ZnFe2O4 and ZnO-ZnFe2O4 catalysts were prepared using the glycine–nitrate process (GNP). The catalyst powders characterized a scanning electron microscope, transmission XRD diffraction studies, selected area pattern studies. addition, specific surface was measured Brunauer–Emmett–Teller analysis. hydrogen reduction in different temperature ranges analyzed H2 temperature-programme...

The effect of iron oxide content on the crystallisation of a diopside glass–ceramic glaze was investigated using a glass–ceramic frit in the K2O–ZnO–MgO–CaO–Al2O3–SiO2 system and a granite waste glass. Measurements by X-ray diffraction (XRD) combined with scanning electron microscopy (SEM) and EDX microanalysis showed that the distribution of Fe ions among different crystalline phases such as f...

ZnFe2O4/?-Fe2O3/ZnO, the ternary transition metal oxide nanocomposite powder was successfully synthesized by facile coprecipitation method directly from metalorganic precursors within 4 h of processing time considerably shorter than other reported methods. To study post-synthesis thermal treatment effects on physical properties, calcination process applied at 500, 600, and 700 °C individually f...

In this study, ZnFe2O4 (ZFO) nanotapers are fabricated on the ZnO nanorods (NRs) by recycling rare-earth oxide (REO) slag as the iron source, which thereby exhibits dramatically enhanced photoelectrochemical (PEC) efficiency. Our studies demonstrate that the electron-hole separation and charge migration can be facilitated by the cascade band alignment of ZFO and ZnO and the branched nanotaper s...

Some spinel ferrites, MFe2O4 (M = Cu, Cd and Zn), having submicron grain sizes (0.1–0.7μm) were prepared by sol-gel-selfcombustion and their sensing properties to reducing gases were investigated. The gas sensing characteristics were obtained by measuring the sensitivity as a function of various controlling factors, like operating temperature, composition and concentration of the gas, and final...

The magnetic recoverable ZnO/ZnFe2O4/diatomite (ZZFDT) composite was synthesized by hydrothermal-precipitation method. structure, optical properties and of the composites were characterized different analytical instruments. ZZFDT-1 is composed cubic spinel, hexagonal wurtzite, tetrahedron structure. SEM TEM showed that ZnO ZnFe2O4 particles loaded onto surface diatomite, particle size uniform. ...

In this paper, Reduced Graphene Oxide (rGO)/ZnFe2O4 (rZnF) nanocomposite is synthesized by a simple hydrothermal method and employed as counter electrode (CE) material for tri-iodide redox reactions in Dye sensitized solar cells (DSSC) to replace the traditional high cost platinum (Pt) CE. X-ray diffraction analysis High resolution Transmission electron microscopy, clearly indicated formation o...
