Abstract

In this present report, effect on iron (Fe) substitution on the structural properties of chromium oxide (Cr2O3) nanoparticles has been investigated in detail. Simple and cost-effective co-precipitation technique was used to synthesize Fe-substituted Cr2O3 nanoparticles at various Fe-concentrations. Structural properties of as-prepared nanoparticles were examined using X-ray diffraction (XRD) technique and Fourier transform infrared (FTIR) spectroscopy. XRD results demonstrated that crystal structure remains single phase up to x = 0.20 of Fe-content. Single-phase Cr2O3 nanoparticles crystallize in rhombohedral crystal structure with space group. Beyond x = 0.20 of Fe-content into Cr2O3 nanoparticles, formation of secondary phase in the form of iron oxide (Fe2O3) has been initiated. Both Cr2O3 and Fe2O3 materials crystallize in same corundum structure with same space group. Hence, we have performed Rietveld refinement for detailed structural study of multi-phase compound. In a multi-component system, phase fraction has also been determined using Rietveld refinement method. FTIR spectra also complement the XRD results and demonstrated the Cr–O and Fe–O vibration band in octahedral environment.
