We synthesized magnetic ZnFe2O4 nanoparticles via one pot solvent free microwave assisted technique. Iron (III) nitrate nonahydrate and zinc nitrate hexahydrate as reactants were crushed in the presence of reactive reagents. Then, the prepared mixture was transferred into a domestic microwave oven with the power of 900 W for 20 minutes. Finally, the resulting compound was collected, washed several times with ethanol, dried at 80 °C for 24 h and analyzed. The constructed nano-sized zinc ferrite was characterized using powder x-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and energy dispersion of x-ray spectrometry (EDX). This technique is a simple, fast, environmental friendly and can draw a usable viewpoint for the synthesis of nanomaterials. The ability of the prepared product was studied on the removal of organic pollutant (Congo Red) from aqueous solution through adsorption mechanism.
Organic reagents can be used as a driving agent to synthesize a wide spectrum of nanomaterials.In this work, nickel molybdate (NiMoO 4 ) nanoparticles with a pure monoclinic crystalline phase were synthesized by using a facile one step microwave heating technique in solid state within a few minutes. Ammonium hepta molybdate tetrahydrate and nickel nitrate hexahydrate as initial materials were mixed to each other without any solvent and put into a domestic microwave oven with one step scheduled run. We introduced an alternative route of power input into chemical reactions in solid state by using microwave radiation. In fact, the obtained results can draw an outlook of the effectiveness and feasibility of this technique for the synthesis of various nanoparticles. Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersion of x-ray spectrometry (EDX) were used to characterize the prepared product. The study of photocatalytic behaviour of the resulting product indicated a high capability on the removal of Methylene Blue (MB) from aqueous solution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
