Characterization and Catalytic Properties of Surface La-rich LaFeO₃Perovskite

Abstract

(B = transition metal) oxides are proved to be highly active catalysts for oxidation reactions in connection with air pollution control. Especially, they are considered as potential catalysts in substitution of noble metal catalysts because of their high thermostability. Many investi-gators have suggested that oxygen vacancies in the perovskite oxides play a major role in catalytic oxidations although there is still debate on the origin of their catalytic activity.
