•Anodic TiO2 films with a doping of Ru ions on the surface were coincidently prepared.•Overpotentials for the evolution of both O2 and Cl2 were greatly reduced•Electrocatalytic activity was determined by amount of Ru on the oxide surface
Anodic TiO2 films with a doping of Ru ions on the surface were coincidently prepared by facile one-step anodization for application of the electrode in electrolysis. We found that the amount of Ru ions on the surface of the oxide could be determined based on the applied potential in KRuO4 electrolyte, which provided negative RuO4– ions through dissociation. Overpotentials for the evolution of both O2 and Cl2 were greatly reduced when the coincidently-Ru-doped TiO2 was employed. The Ru-doped electrode prepared at 60 V showed the highest electrocatalytic activity due to the largest amount of Ru incorporation in the oxide.
