This study investigated the impact of alkali metal cation occupancy on the formation of O vacancies in spinel-type titanium oxide. The results suggested that substituting the cation at the 8a-site could enhance catalytic oxidation activity.
In this study, density functional theory calculations determined that the formation of O vacancies in spinel-type titanium oxide is affected by the alkali metal cation occupying the 8a-site. This result indicates that substitution of the 8a-site cation, such as Li+-> Na+, should improve catalytic oxidation activity. Experimental results confirmed that Au supported on sodium titanate (Na3LiTi5O12) showed improved catalytic CO oxidation activity compared to Au supported on lithium titanate (Li4Ti5O12).
