Influence of Preparation Conditions of Mixed-valence Co/ZSM-5 Zeolites on Their Adsorption and Catalytic Properties in CO Oxidation
Published 2002-05-01“…The adsorption properties, thermal stability and catalytic activity in CO oxidation of Co 2+ , Co 3+ -containing ZSM-5 zeolite systems with different metal loadings were studied. Treatment in H 2 caused an increase in the activity of Co 2+ /ZSM-5 and Co 2+ –Co 3+ /ZSM-5 systems, but the activity of the Co 3+ /ZSM-5 system remained unchanged, demonstrating the very low reducibility of the [Co(NH 3 ) 6 ] 3+ ion when embedded in the zeolite framework. …”
