Abstract

In this study, the density functional theory was employed to analyze from a theoretical point of view the reaction of CO and CO2 with the surfaces of BaTiO3(001). Our results showed that the adsorption of CO is more stable on the TiO2-terminated than on the BaO-terminated slab. Additionally, this interaction led to the stable formation of CO3 on the TiO2-terminated slab. Similarly, the chemisorption of CO2 on both surfaces showed to be high stable, and it led to the CO3 formation on the BaOT slab. Moreover, in order to investigate the possibility of carbon deposition, the CO disproportionation reaction was considered to occur via the Eley-Rideal reaction mechanism. However, it was observed that the carbon deposition is quite energetically demanding, more challenging for the BaO-terminated surface than for the TiO2-terminated, and might not occur at the operating conditions of the solid oxide fuel cells.
