摘要：

Anodic characteristics of La1-xSrxMnO3 electrodes were investigated in alkaline solutions. It was found that the catalytic activity for the oxygen evolution reaction was relatively high and increased with the increase of x in La1-xSrxMnO3. The primary discharge step of hydroxide ion is rate-controlling in the anodic evolution of oxygen at La1-xSrxMnO3 electrodes. The catalytic property for this reaction is discussed by applying the theory of σ* band formation to the interaction between the eg orbital of Mn cation and the electron orbital of hydroxide ion. © 1979.
