This work presents the first experimental evidence for the effect of support morphology (ceria) on metal oxide (vanadia) catalysis. The morphology determines the amount of defect sites available in ceria support and thus affects greatly both the catalytic activity and selectivity of supported vanadia catalysts in alkane oxidative dehydrogenation reaction.
