Ethane oxidehydrogenation selectivity and reductibility of mixed NiVSb oxides

摘要

Alumina-supported NiV, SbV and NiVSb oxides were characterized and tested as catalysts for the oxidehydrogenation of ethane. The results of their surface and bulk reduction by hydrogen revealed that the most easily reduced NiVSb catalyst was the most selective. The relationship between catalyst reducibility and selectivity was interpreted on the assumption that the reaction occurred through a redox mechanism.
