Abstract
The nickel substituted copper ferrite nanoparticles (NixCu1-xFe2O4), where x = 0.0, 0.2, 0.4, 0.6, 0.8, 1.0) were prepared by simple and economic coprecipitation method and characterized by various physicochemical methods such as XRD analysis, IR spectrometry, FEG-SEM and EDS. The XRD analysis showed that all the samples formed have single-phase cubic structure. The FEG-SEM analysis data reveals that the particle size of the compounds lie in the range 13.9 to 31.8nm. The nanoparticles synthesized are useful in the catalytic reactions and are ~100% selective for the acetylation of selected phenols. The catalysts were found to be magnetically separable and reusable without any further treatment. These ferrospinel nanoparticles were found to have better catalytic activity as compared to the corresponding metal oxides. The present nanoparticle catalysts offer high yields in a short reaction time and moderate reaction conditions.
