Catalytic Activity of Perovskite-Type Oxides for the Direct Decomposition of Nitrogen Monoxide

Abstract
Perovskite-type oxides showed the catalytic activity for NO decomposition above 773 K, which depended largely on constituent metal cations and their composition. Results obtained indicate that perovskite-type oxides such as La0.8Sr0.2CoO3 are a promising NO decomposition catalyst having high activity and thermal stability at elevated temperatures.
