Brownmillerite related compounds Ba_2In_2O_5, Ba_3Y_4O_9 and BaLa_2O_4 having oxygen vacan cies were synthesized. Ionic conductivity and the cata lytic activity for the reduction of NO_x to N_2 increased at the temperature of order disorder transition of the oxygen vacancies of Ba_2In_2O_5, Ba_3Y_4O_9 and BaLa_2O_4. And it was found that the catalylic activity by order disorder transition of oxygen vacancies is hardly influenced by the coexistence with oxygen or propylene (C_3H_6) . Froun these results, it was clarified that the catalytic activity for the NO_x decomposition reaction appears at a lower temperature by controning the or der disorder transition temperature of oxygen vacan cies. Moreover, it was suggested that the oxygen vacan cy is an important factor in the reduction of NO_x to N_2, and the diffusion of oxygen vacancy appeared at the or der disorder transition temperature., rights: 社団法人日本セラミックス協会
