摘要 通过有机酸辅助法在较低温度下合成了Ｌａ０．８Ｓｒ０．２ＣｏＯ３ 复合氧化物，ＸＲＤ结果表明，用该方法合成的Ｌａ０．８Ｓｒ０．２ＣｏＯ３ 具有单相钙钛矿结构，从稳态物化曲线得出，在碱性溶液中，在Ｌａ０．８Ｓｒ０．２ＣｏＯ３ 表面的析氧Ｔａｆｅｌ斜率为６５ｍ Ｖ／ｄｅｃ，ＯＨ－的反应级数为１，在分析了反应机理后，得出了析氧反应的动力学方程，恒电流测试结果表明，用该方法制备的Ｌａ０．８Ｓｒ０．２ＣｏＯ３／Ｎｉ电极，在碱性溶液中具有良好的析氧催化活性。 La 0 8 Sr 0 2 CoO 3 complex oxide has been synthesized at moderate temperature by organic acid aided method.XRD result shows that La 0 8 Sr 0 2 CoO 3 synthesized by this method has perovskite structure of single phase.It was revealed from steady state polarization that the Tafel slope of oxygen evolution on La 0 8 Sr 0 2 CoO 3 was 65mV/dec and the reaction order with respect to OH was unity.The rate equation for oxygen evolution in alkaline solution was formulated after analyzed the mechanism.Galvanostatic measurements reveal the La 0 8 Sr 0 2 CoO 3/Ni electrode prepared by this method has high electrocatalytic activity for oxygen evolution in alkaline solution.
