The importance of nickel oxyhydroxide deprotonation on its activity towards electrochemical water oxidation

). Furthermore, we propose a mechanism for the OER on NiOOH which is consistent with the observed pH-sensitivity, and that also explains why NiOOH is not a suitable catalyst for applications in neutral or moderately alkaline pH (in the range 7-11), apart from the lower stability of the catalyst under these conditions.
