Abstract A set of new materials with general formula [M(H2O)]X(VO)1−XPO4·2H2O (M 3+=Al, Cr, Ga, Mn), isomorphous with layered tetragonal VOPO4·2H2O and having potential catalytic properties, have been characterized by TG and DTA, X-ray diffraction and surface acid strength. During heating the compounds transform in the monohydrated and anhydrous phases, all maintaining a layered structure, with a proper interlayer spacing. Catalytic tests performed with 1-butene show that theM 3+-vanadyl phosphates greatly improve the conversion of the olefine with respect to pure vanadyl phosphate.
