This work compares the capacity of generating the surface oxygen vacancies over SrTiO3, BaTiO3 and the mixed Sr0.5Ba0.5TiO3. This aspect is elucidated by significantly different chemical states of the elements on the surface of the three materials. Along with the fundamental materials aspect, CO oxidation studies complement the highest surface reducibility of the Sr0.5Ba0.5TiO3 catalyst. With detailed adsorption-desorption studies, we report that the A-site cation substitution renders a better surface-reducibility induced catalytic activity for CO oxidation.
