Ce_1-xSm_xO_2-δ (x = 0.0, 0.1, 0.2, 0.3) samples were prepared by sucrose and pectin–assisted auto combustion method. The phase identification, morphology, spectroscopic properties, and electrical properties of the samples are studied by XRD, FESEM, Raman spectrometer, and impedance spectroscopy. Rietveld refinement was carried on XRD samples for structural properties. Samples showed a single phase with the cubic fluorite structure. The average crystallite size was in the range of 10–17 nm. The sample Ce_0.8Sm_0.2O_2−δ exhibits improved conductivity with low activation energy in comparison with pure ceria.

蔗糖-果胶辅助自动燃烧过程对Ce 1-x Sm x O2-δ的结构表征和电性能

 用蔗糖和果胶辅助的自动燃烧法制备了Ce _1-x Sm _x O2 _-δ（x = 0.0、0.1、0.2、0.3）样品。通过XRD，FESEM，拉曼光谱仪和阻抗谱研究了样品的相识别，形态，光谱性质和电性质。对XRD样品进行Rietveld精炼以获得结构特性。样品显示具有立方萤石结构的单相。平均微晶尺寸在10–17 nm范围内。与纯二氧化铈相比，样品Ce _0.8 Sm _0.2 O _2-δ表现出改善的电导率和较低的活化能。
