| Outline of Final Research Achievements |
In this study, we have investigated complex-oxide catalysts for CO2 gasification of carbon material. It is found that alkaline-earth containing perovskites significantly accelerate CO2 gasification reaction kinetics. BaSnO3 and BaCeO3 showed particularly high catalytic activity for CO2 gasification. The detailed structural and chemical analyses suggest that Ba-O-C complex is formed at the contact point of catalyst and carbon. Then CO2 adsorbed on the complex is activated and promote gasification of carbon.
