Abstract：In order to improve the electrochemical catalytic activity of double perovskite oxide SmBaCoCuO5+δ,cation vacancies were introduced at Ba site.The effects of cation vacancies at Ba site on crystal structure,thermal and electrochemical catalytic properties were investigated.The results show that the introduction of Ba-site cation vacancies shrinks the cell volume and increases the oxygen vacancy content,thereby reducing the thermal expansion coefficient of the material and effectively improving the electrochemical catalytic performance.
