Influence of iron doping on tetravalent nickel content in catalytic oxygen evolving films [electronic resource]
Iron doping of nickel oxide films results in enhanced activity for promoting the oxygen evolution reaction (OER). Whereas this enhanced activity has been ascribed to a unique iron site within the nickel oxide matrix, we show here that Fe doping influences the Ni valency. The percent of Fe<sup>...

| Summary: | Iron doping of nickel oxide films results in enhanced activity for promoting the oxygen evolution reaction (OER). Whereas this enhanced activity has been ascribed to a unique iron site within the nickel oxide matrix, we show here that Fe doping influences the Ni valency. The percent of Fe<sup>3+</sup>doping promotes the formation of formal Ni<sup>4+</sup>, which in turn directly correlates with an enhanced activity of the catalyst in promoting OER. Finally, the role of Fe<sup>3+</sup>is consistent with its behavior as a superior Lewis acid. |
