| Abstract: | The technique of electrospinning was employed to fabricate Sm2O3 and Nd2O3 co-doped CeO2 nanofiber electrolytes. The phases and morphology were observed by X-ray diffraction, scan electron microscopy, and transmission electron microscope. With respect to calcination temperature, the electrical conductivity of the nanofiber electrolytes was measured in air. The results indicate that the nanofibers calcined at various temperatures all exhibit a cubic fluorite structure. The nanofibers calcined at 400 oC with an average diameter of 402 nm and grain size of 5 nm have the highest electrical conductivity. |
