摘要
对钙钛石型氧化物催化剂进行分类 ,探讨催化剂元素组成、结构与性能间的关系 ,并介绍多种催化剂的制备方法 .在对氧化物反应法、盐分解法、共沉淀法及无定形羟酸前驱体法进行分析研究的基础上发现 ,由于无定形苹果酸前驱体法具有制备温度较低、催化剂比表面积大、工艺过程简单的特点 ,是最佳的合成方法之一 .
In this paper the relationship between the elemental composition and catalytic performance of perovskite-type oxides as electrocatalysts was investigated.The various preparative methods,such as oxide reaction,nitrate or acetate decomposition,precipitation and hydroxy acid-aided synthesis,were introduced.It was proved that one of the best ways is the amorphous malate precursor method,by which the preparative temperature is low and the obtained catalysts have high specific surface area.
