A Comparison of the Electrical Properties of Co-doped Ceria and Tri-Doped Ceria for Energy Applications

In comparison to other Periodic Table elements, rare earth elements demonstrate long-term stability and strong conductivity. Ceria nanomaterial has found many applications in numerous technologies. Doped ceria was prepared by many wet chemical methods. In this paper, we examine the electrical properties of the ceria after adding three dopants, two of which are rare earth elements (Gd and Nd) and one metal (Ca). The compositions, Ce0.75Gd0.05Nd0.2O2 and Ce0.75Gd0.05Nd0.14Ca0.06O2, were formed using the WOWS (without water and surfactant) Sol-Gel method. The X-ray diffraction (XRD) technique was used to investigate the crystallinity of nanostructures. The structure of both samples was cubic. For the electrical measurements, the Precision Analyzer was used for doped Ceria as a function of temperature. With the variation in composition, the electrical properties changes.
