摘要
LaCoO3是典型的ABO3型钙钛矿化合物。它具有优异的化学稳定性和高温下的良导电性,在环境催化分解、汽车尾气处理、巨磁阻材料、二次电池和燃料电池的电极材料等方面都有着十分广泛的应用前景。通过XRD谱和XPS研究发现,固相烧结法制备LaCoO3的最佳配比为Co La=105%,最佳烧结时间为50小时。
LaCoO3 is a typical ABO3 perovskite-type compounds. It has excellent chemical stability and good e-lectrical conductivity under high temperature,due to their potential applications in energetics both as cathodes and solid electrolytes in solid oxide fuel cells,and both in environmental catalysis for pollutant decomposition and colossal magnetoresistance materials. Found by XRD and XPS studies,the best ratio of synthesis of LaCoO3 by solid-phase sintering method is Co La=105%,the optimum sintering time of 50 hours.
