Synthesis and Catalytic Properties of Nanosized Zinc and Nickel Ferrites
Nanosized NiFe2O4 and ZnFe2O4 were synthesized by the citrate combustion method. The nanopowders were characterized by elemental analysis and powder X-ray diffraction; size, dispersion, and morphological features were determined. It was established that the nanopowders of the synthesized ferrite spinels (average particle size 38 ± 3 nm for NiFe2O4 and 49 ± 3 nm for ZnFe2O4) are effective catalysts for the oxidation reaction of methylene blue dye (degradation efficiency 92% for nickel ferrite and 95% for zinc ferrite). The observed dependence of the catalytic activity of nanosized ferrites on the type of illumination is more pronounced for nickel ferrite (a 2.5-fold increase in the reaction rate constant and a 31% increase in the degradation efficiency).
期刊介绍：
Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
