| Research Abstract |
Effect of Ba dispersion and crystal structure on the catalytic performance of supported Ba catalyst, which shows surface basicity, for direct decomposition of NO was investigated. It was found that highly dispersed Ba species are catalytically active sites for NO decomposition reaction. Highly dispersed Ba species were also found to promote effectively the formation of NO_ 2- species as intermediate. We proposed the importance of surface basicity of support oxide to obtain highly dispersed Ba species, leading to development of highly active NO decomposition catalyst consisting suitable NO_x adsorption and reaction sites.
