The catalytic activity of B-site binary composite perovskite oxide LaFeyMn1-yO3 for ammoxidation was studied. The catalyst was characterized by various means. The relationship between NO selectivity in ammoxidation and the chemical properties of the catalyst, Katsushika, was discussed. It is found that the structure of the catalyst and the redox properties of the transition metal ions are important factors that affect the physico-chemical properties and catalytic performance of the catalyst. The effect of a small amount of B doping on NO selectivity is significant. The NO selectivity in the Mn-rich region is mainly determined by the concentration of Mn4 + ions. The iron-rich region is mainly related to the state of Fe ions and the defect structure of the catalyst.
