Vanadia monolayers deposited on various oxide supports (Zr02, Nb(2)O(5), TiO2, Al(2)O(3) and Si0(2) have been investigated with the aid of electron spin resonance. The results show that the electronic structure of reduced vanadyl species generated during methanol chemisorption depends on the nature of the supporting matrix. This is shown by changes of theBeta(2) bonding coefficient calculated from the experimentally determined ESR parameters. I t is demonstrated that the catalytic activity in methanol oxidation, ex-pressed in terms of turnover frequency (TOF), can be correlated with the latter parameter and increases with the ionicity of the vanadyl in-plane Pi-bonding system.
