Abstract
One-step solution combustion of ZnFe2O4 and ZnFe1.6O4 nanoparticles was represented. To obtain a better dispersion of nanoparticles with high specific surface area values, salt-assisted solution reaction was applied using KCl as a key criterion. Structure, chemical composition, microstructure, photoluminescence emissions, magnetic properties, and band gap of the samples were also studied. Results showed that ZnFe2O4 and ZnFe1.6O4 crystalline phases were synthesized in a one-step combustion reaction without any post-heating process requirement. The cation distributions amongst tetrahedral and octahedral sites in samples were estimated by modified Bertaut method using XRD data. Both stoichiometric and non-stoichiometric zinc ferrites had a partial reverse spinel structure with high degree of inversion. FTIR spectra demonstrated some bands associated with Fe–O and Zn–O bonds. Moreover, no unwanted impurity such as nitrate was detected in synthesized powders. Microstructure and nitrogen adsorption/desorption studies showed that the synthesized powders were mesoporous with high specific surface area, together with agglomerated nanoparticles. Magnetization curves showed that both ZnFe2O4 and ZnFe1.6O4 samples were superparamagnetic materials.
