We present analysis of the indirect role of Co doping on the electrocatalytic activity of α-Fe<sub>2</sub>O<sub>3</sub>. Upon substitution of one of the Fe atoms in the hematite surface, we observed a promoting effect of the substitution, upon which the overpotential required for the water-splitting reaction decreased in all substitution sites investigated. The cobalt site itself, however, does not exhibit the improved properties with respect to the undoped hematite. The promoting effect results ...[more]
