Preparation of perovskite-type oxide by thermal decomposition of cyano complex

摘要

Introduction Perovskite-type mixed metal oxide is one of the attractive compounds used in the environmental friendly catalytic systems. It is well known that the catalytic activity of perovskite-type oxide was strongly dependent on the preparation method. We reported that perovskite-type oxide catalyst could be prepared by the thermal decomposition of organic metal cyano complex at low calcination temperature because of the structure similarity between organic metal cyano complex and perovskite-type oxide [1]. In this study, the decomposition process of cyano complex, Sm[Fe(CN)6]·4H2O and the catalytic activity of resulting perovskite-type oxide were investigated.
