摘要
Ba 2 In 2 O 5 , Ba 3 Y 4 O 9 , and BaLa 2 O 4 having brownmilleriterelated structures were synthesized. Ionic conductivity and catalytic activity following the reduction or NO to N 2 were also investigated, both or which increased at the order-disorder transition temperature for oxygen vacancies or these compounds. It was made clear that the catalytic activity or NO decomposition reaction increased with a decrease in the order-disorder transition temperature. Moreover, it was round that ionic conductivity contributed to the catalytic activity or NO reduction to N 2
