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. 收起
