The influence of calcium doping on the electrocatalytic activity of amorphous lanthanum cobaltite a-La1–yCayCoOx with respect to the oxygen evolution reaction in 0.1 M KOH is investigated. The introduction of calcium slightly decreases the activity and does not hamper the short-term stability very much. a-La0.7Ca0.3CoOx demonstrates the highest activity among the calcium-containing materials, which is ascribed to the higher concentration of Co3+ and lower film resistance as determined from ex situ X-ray photoelectron spectroscopy and electrochemical impedance spectroscopy.
