Abstract

As global warming problem caused by greenhouse gas (GHG) emissions accelerates, many methods to remove carbon dioxide (CO₂) have been proposed. In particular, CO₂ decomposition has been developed for GHG emission reduction and CO₂ upcycling. Our group previously reported on the results of efficient CO₂ decomposition using SrFeO_3-δ (perovskite-type metal oxide). According to the results of the isothermal test of SrFeO_3-δ, reaction for a long time at high temperatures is necessary for effective CO₂ decomposition, and this may lead to inefficient energy use. Therefore, in this study, Rh and Ru were impregnated as catalysts to SrFeO_3-δ. As a result of CO₂ decomposition using these catalysts, CO₂ decomposition appeared at a low temperature of ∼200 °C. The maximum produced CO concentration was 3 times higher due to the spillover phenomenon of the precious metal catalysts. The cyclic tests showed catalyst stabilities of Rh- and Ru-SrFeO_3-δ as well as the potential for continued and improved CO production. In additions, this study demonstrated that the decomposition of CO₂ and the production of CO are performed by reverse Boudouard reactions as well as oxygen vacancies. It is expected that these results will contribute to GHG emission reduction.
