“…Thus, the catalytic behavior for oxidative conversion of methane and oxidative coupling of methane was investigated over pure and neodymium substituted zinc ferrites ( Fig. 10) prepared by combustion method (Papa et al, 2010). The catalytic activity proved to be strongly related to the oxide structure as well as to the specific defects created by substitution.…”

Recent applications of ferrite nanoparticles as catalysts in organic processes are reviewed. Catalytic applications include the use of mainly cobalt, nickel, copper, and zinc ferrites, as well as their mixed-metal combinations with Cr, Cd, Mn and sometimes some lanthanides. Core-shell nanostructures with silica and titania are also used without loss of magnetic properties. The ferrite nanomaterials are obtained mainly by wet-chemical sol-gel or co-precipitation methods, more rarely by sonochemical technique, mechanical high-energy ball milling, spark plasma sintering, microwave heating or hydrothermal route. Catalytic processes with application of ferrite nanoparticles include decomposition (in particular photocatalytic), reactions of dehydrogenation, oxidation, alkylation, C-C coupling, among other processes. Ferrite nano catalysts can be easily recovered from reaction systems and reused up to several runs almost without loss of catalytic activity.

Spinel MFe 2 O 4 (M ¼ Cu, Co and Zn) ferrites have been successfully synthesized via a wet chemical process assisted by albumin matrix and employed as catalyst for methylene blue (MB) degradation. The materials have been characterized by different techniques including X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), high resolution transmission electron microscopy (HR-TEM), field emission scanning electron microscopy (FESEM), Raman spectroscopy, Mössbauer spectroscopy, vibrating sample magnetometry (VSM) and N 2 adsorption-desorption isotherm. The crystallite size is found to vary from 13 to 43 nm depending on the calcination temperature and they exhibit low BET surface area. Spherical and rod like surface morphology is obtained for porous copper and zinc ferrite. Copper and cobalt ferrite exhibit ferromagnetic properties typical of nanomaterials. On the other hand zinc ferrite shows superparamagnetic behavior. The current ferrites, specifically copper ferrite, are reported to exhibit significant catalytic activity for the photodegradation of methylene blue in the presence of H 2 O 2 under visible light. All the ferrite materials show better activity in acidic medium.
