Influence of iron doping on tetravalent nickel content in …
Abstract. 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 3+ doping promotes the formation of formal …
