Oxygen Evolution on La1 − x Sr x CoO3 Electrodes in Alkaline Solutions

摘要: Anodic characteristics of (with ) electrodes were investigated in alkaline solutions. It was found that the catalytic activities for oxygen evolution reaction are relatively high and activity electrode with is higher than . The secondary chemical step, i.e., , rate‐controlling reaction. Therefore, it concluded rate step more rapid at value because beneficial effect positive charge on Co cation this step. suitable anode material solutions, anodic dissolution scarcely occurs.
