Room temperature partial oxidation (corrosion) of cubic CoO led to the formation of mixed valence CoOx with better electrochemical water oxidation activities in alkaline pH. Activation of both octahedral Co3+ and Co2+ to layered oxohydroxide–hydroxide during alkaline electrochemical water oxidation has been demonstrated.
