Abstract
Temperature-programmed reduction (TPR) and temperature-programmed oxid ation (TPO), combined with differential thermal analysis (DTA) and FT- IR spectroscopy, were used to characterize trimanganese tetroxide cata lysts. It was found that the redox behavior of Mn3O4 Was considerably affected by different gas treatments, preparative condition and the ad dition of a promoter. A possible interpretation of two reduction peaks in the TPR profile of Mn3O4 has been suggested.
