摘　　要：钙钛矿型氧化物Sm_(0.5)Sr_(0.5)CoO_(3-δ)(SSC)因具有混合离子-电子传导性、高电导率、良好的催化活性以及氧离子扩散性等优异的电化学性能,在固体氧化物燃料电池及电催化等诸多清洁能领域被广泛作为高性能的电极材料。不同制备方法决定了SSC材料形成纯相所需的不同煅烧温度,同时赋予了SSC材料不同的结构形貌,进而影响了其具体的应用方向。对SSC基材料的各种制备方法进行了总结。Perovskite oxide of Sm_(0.5)Sr_(0.5)CoO_(3-δ)(SSC) has been widely used as high-performance electrode material in many clean energy fields including solid oxide fuel cell and electrocatalysis, due to its excellent electrochemical properties such as mixed ion-electron conductivity, high electrical conductivity, good catalytic activity and oxygen ion dispersion. Different preparation methods determine different calcination temperatures to form phase pure SSC materials and give SSC materials with different structural morphology, which affects the specific application direction of SSC materials. The preparation methods of SSC are summarized in this paper.
