摘要：
The impact of different calcination temperature (550, 650, 750 and 850 degrees C) on the structural/electrical properties of sintered Cu/Sm co-doped CeO2 prepared by sol-gel combustion were studied. Structural properties were studied by X-ray diffraction (XRD), Raman spectroscopy and ultraviolet-visible spectroscopy (UV-VIS). The composition, oxidation state and electrical conductivity of sintered samples were investigated by photoelectron spectroscopy (XPS) and electrochemical impedance spectroscopy (EIS), respectively. With the increasing calcination temperature, both the oxygen vacancy and Ce3+ increase. Therefore, the highest conductivity was obtained for samples calcined at 850 degrees C.
