Evaluation of microstructure, magnetic properties and catalytic application of Co2+ and Cr3+ doped Ni- Zn spinel ferrite

Cobalt and chromium doped ferro spinels synthesized by sol-gel auto-combustion method with glycine as a fuel, calcination temperature of samples confirmed from TGA/DSC analysis. The observed elemental analysis from EDAX is in good agreement with the theoretical composition of elements. The XRD and Rietveld analysis of XRD patterns illustrate formation of single- phase cubic spinel structure. The IR spectra shows two principle absorption bands. SEM and TEM images reveal well-defined nanoparticles with slight agglomeration. Calculated and observed magneton number decreased with Co2+ and Cr3+ substitution. 1, 8-dioxodecahydroacridines synthesized using synthesized ferrite nanoparticles as a catalyst.

Automated summary

Cobalt and chromium doped ferro spinels were synthesized using the sol-gel auto-combustion method with glycine as a fuel. The calcination temperature of the samples was determined by TGA/DSC analysis. The results of elemental analysis, XRD, Rietveld analysis, IR spectra, SEM, and TEM all indicate the successful synthesis of the desired structures and well-defined nanoparticles. Additionally, the synthesized ferrite nanoparticles were used as a catalyst for the synthesis of the target product, 1, 8-dioxodecahydroacridines.
