the aim of this study is to evaluate the influence of ph on the synthesis of nanocrystallines cobalt ferrite by combination of sol- gel auto combustion and ultrasonic irradiation methods. two different fuels, urea and thiourea, along with metal nitrates (oxidant) were used to prepare cofe2o4 powders. the morphology of the resulting powders was investigated. the powders were characterized by x-r...

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...

ZnO and ZrO2 photo catalysts were synthesized by sol-gel auto combustion method. The products were characterized by X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). Structural and morphological properties of nano particles were investigated and the average crystalline size of ZnO and ZrO2 was obtained 44 and 51 nm, respectively. Also, photo catalytic degrada...

Current study represents the effect of the size and synthesis method on the cation distribution of cobalt ferrite nanoparticles and on the magnetic properties. The nanoferrites have been synthesized through sol-gel auto-combustion method using metal nitrates as precursor and citrate as fuel. In order to obtain the fine and agglomerated-free particles, we have used salt-assisted combustion react...
