Green Synthesis Approach for Nanosized Cobalt Doped Mg–Zn through Citrus Lemon Mediated Sol–Gel Auto Combustion Method

Abstract

Cobalt doped Mg–Zn ferrite (Mg_(0.56)Co_(0.14)Zn_(0.30)Fe₂O₄) was synthesized by the modified sol–gel auto combustion method (MSG) in which lemon extracts were used as the source of energy. X-ray diffraction (XRD) technique was employed to confirm the formation of cubic spinel ferrite phase. The lattice parameter was evaluated to be 8.39 Å with an average crystallite size ranging from 41–51 nm. Dislocation density, mechanical properties, and hopping length were determined. Crystallite size and strain were evaluated using W–H plot and size–strain plot.
