摘要：

Ba2In2O5, Ba3Y4O9, and BaLa2O4 having brownmillerite-related structures were synthesized. Ionic conductivity and catalytic activity following the reduction of NO to N2 were also investigated, both of which increased at the order-disorder transition temperature for oxygen vacancies of these compounds. It was made clear that the catalytic activity of NO decomposition reaction increased with a decreased in the order-disorder transition temperature. Moreover, it was found that ionic conductivity contributed to the catalytic activity of NO reduction to N2.
