nanomagnetic mgfe2o4 is an active, stable, and reusable catalyst for the oxidation of alcohols. the oxidation of various primary and secondary alcohols has been examined and related corresponding products were obtained in good yields. the reactions were carried out in the presence of water as solvent and oxone (at room temperature) or h2o2 (at 60 ºc) as an oxidant. the catalyst was investigated...

Nanocrystalline magnesium ferrite is synthesized by high-energy ball milling. The formation of nanocrystalline ferrite phase is observed after 3 h of milling and its content increases with milling time. The structural and microstructural evolution of the nanophase have been studied by X-ray powder diffraction and the Rietveld method. After 3 h of milling, ferrite phase (mixed spinel) nucleates ...

in the present work, magnetic nanocomposites of the multi-walled carbon nanotubes (mwcnts) decorated with magnesium ferrite (mgfe2o4) nanoparticles were synthesized successfully by citrate-gel method. the shape, structure, size, and properties of the as-synthesized sample were characterized by fourier transform infrared spectroscopy (ftir), x-ray diffraction pattern (xrd), transmission electron...

The influence of various cations ranging from alkali metals to transition metals according to the periodic table were discussed. The ferrites used were Ni ferrite, Mg ferrite and Zn ferrite having different cation distributions in the spinel lattice. Cations having appropriate ionic radii and valencies are soluble in ferrite. Several additives formed other phase in addition to the spinel phase....

Magnesium ferrite (MgFe(2)O(4)) nanostructures were successfully fabricated by electrospinning method. X-ray diffraction, FT-IR, scanning electron microscopy, and transmission electron microscopy revealed that calcination of the as-spun MgFe(2)O(4)/poly(vinyl pyrrolidone) (PVP) composite nanofibers at 500-800 degrees C in air for 2 h resulted in well-developed spinel MgFe(2)O(4) nanostuctures. ...
