摘要
使用固溶包覆法成功合成了La_(0.8)Sr_(0.2)MnO_(3-σ)(LSM)包覆Ba_(0.5)Sr_(0.5)Co_(0.8)Fe_(0.2)O_(3-σ)(BSCF)的LSM-BSCF复合粉体,分析了复合粉体的物相组成,形貌结构,抗CO_2气体毒化能力以及相应电极电化学性能,结果表明所制备的粉体成相良好,具有较好的抗CO_2毒化性能,而电化学性能有所降低。
La_(0.8)Sr_(0.2)MnO_(3-σ) coated Ba_(0.5)Sr_(0.5)Co_(0.8)Fe_(0.2)O_(3-σ)(LSM-BSCF) composite powders was successfully synthesized by solid-solution method. Some property of material was investigated, such as the phase composition, morphology, ability of ant-CO_2 gas poisoning, and electrochemical performance. The result showed the material have good crystal structure, well ability of ant-CO_2 gas poisoning, and the electrochemical performance is reduced.
