Title
Dispersion of VOPO4·2H2O on different supports through exfoliation and their catalytic activity for the selective oxidation of cyclohexane
Abstract

The VOPO4·2H2O phase has been exfoliated in 2-propanol and dispersed on different supports such as alumina, KIT-6, CeO2 and ZrO2 at 50% loadings and at different VPO/support ratios in the case of alumina. It has been found that the nature and amount of the support has a profound influence on the crystallinity and morphology of the dispersed VPO phase which in turn, has a marked effect on its catalytic activity for the oxidation of the cyclohexane.
