چکیده

Abstract

Characterization and application of calcium ferrites based solid solutions containing active oxygen species for catalysts in propylene total and methane partial oxidation has been studied. The calcium ferrite based solutions containing brownmillerite phases showed a structural transition based on the migration of oxide ions at high temperature. The calcium ferrite solution provided two types of active  oxygen  species  due  to  the  existence  of  the  brownmillerite  phase.  These  oxygen  species  individually played important roles in the propylene and methane oxidation mechanisms.
