Vanadium based catalysts with the following compositions: 30%V2O5–70%MgO, 30%V2O5–70%SiO2 and 30%V2O5–40%MgO–30%SiO2 were prepared by the wet impregnation method using MgO and/or SiO2 as support. The structure, texture and morphology of the active phase strongly depend on the choice of support: for 30%V2O5–70%MgO, thin particles of Mg3V2O8 were identified with TEM (associated to EDS) together with MgO particles while large V2O5 particles beside silica particles bearing vanadium species on their…
