The crystal structure of Co-based perovskite oxides (ACoO) can be controlled by adjusting the A-site elements. In this study, we synthesized YBaCoO ( = 0, 0.5, and 1.
View Article and Find Full Text PDFPt-based catalysts are commonly employed as NO-trapping catalysts for automobiles, while perovskite oxides have received attention as Pt-free NO-trapping catalysts. However, the NO storage performance of perovskite catalysts is significantly inferior at low temperatures and with coexisting gases such as HO, CO, and SO. This study demonstrates that NO storage reactions proceed over redox site (Mn, Fe, and Co)-doped SrTiO perovskites.
