| 摘 要： | 用酒石酸辅助法制备了Ｌａ１－ｘＳｒｘＣｏＯ３系列钙钛矿氧化物，结果表明，采用该方法可在较低温度下形成高比表面的钙钛矿，Ｓｒ取代Ｌａ有助于形成均相多孔的表面，提高氧化物的比表面。电化学研究表明，钙钛矿氧化物膜电极Ｎｉ／Ｌａ１－ｘＳｒｘＣｏＯ３在碱性溶液中表现出很高的析氧电催化活性和良好的稳定性。

| Abstract: | La1-xSrxCoO3 series perovskite oxides were prepared by tartaric acid-aided method.The XRD, SEM and CV results indicated that perovskites with high specific surface area can be prepared at moderate temperature by this method and the substitution of Sr for La in the oxide lattice was helpful to the formation of uniform and porous surface and the increase of its specific surface area. The electrochemical results suggested that the perovskite oxide film eIectrode Ni/La0.8Sr0.2CoO3 exhibited the highest electrocatalytic accivity among all the others prepared and a high stability. |
