CeXO2 (X: Fe, Mn) nanoparticles, synthesized using the coprecipitation route, were investigated for their structural, morphological, magnetic, and electrochemical properties using X-ray diffraction (XRD), field emission transmission electron microscopy (FE-TEM), dc magnetization, and cyclic voltammetry methods. The single-phase formation of CeO2 nanoparticles with FCC fluorite structure was confirmed by the Rietveld refinement, indicating the successful incorporation of Fe and Mn in the CeO2 matrix with the reduced dimensions and band gap values. The Raman analysis supported the lowest band gap of Fe-doped CeO2 on account of oxygen non-stoichiometry. The samples exhibited weak room temperature ferromagnetism, which was found to be enhanced in the Fe doped CeO2. The NEXAFS analysis supported the results by revealing the oxidation state of Fe to be Fe2+/Fe3+ in Fe-doped CeO2 nanoparticles. Further, the room temperature electrochemical performance of CeXO2 (X: Fe, Mn) nanoparticles was measured with a scan rate of 10 mV s−1 using 1 M KCL electrolyte, which showed that the Ce0.95Fe0.05O2 electrode revealed excellent performance with a specific capacitance of 945 Fּ·g−1 for the application in energy storage devices.

The unique characteristics of rare earth elements, attributed to their distinctive 4f electron band, hold significant potential for enhancing the stability and effectiveness of inorganic anticorrosion materials. In this study, rod-shaped samarium-doped zinc oxide solid solution (ZSO) material was synthesized under pure inorganic conditions. The protective effect of the 4f electrons of samarium on the 3d electrons of zinc enhances the chemical stability of the material. Furthermore, the ZSO material exhibited the ability to utilize photogenerated electrons for preventing metal corrosion. Tests have shown that the corrosion resistance of the ZSO composite shield is 78.3% higher than that of the zinc oxide shield and 202.3% higher than that of the epoxy resin coating. Under sunlight, the ZSO composite shield exhibits further improved corrosion inhibition efficiencies of 40% and 100%. The protective effect may be extended to other rare earth and transition metals, leading to the development of more stable and durable materials.
