structure
hello,
I wonder if the vanadium, vanadium oxides, when used as catalysts in the reactions in the solid state, can alter the structure of a material.

Your question is not specific. Maybe if you provide information of your synthesis some members may help you.

it is known that vanadium oxide can act as a catalyst. yet we know that the catalyst does not change the status of a final product of a reaction and
he is kinetic. I wonder if these oxides, such as intervention by its catalysts can state a structural product of monoclinic to tetragonal, for
example, or else in particular for solid solid reaction.

Yes and no, it varies with the specific case - which you are not supplying.
Plus you are making assumption. The vanadium based catalyst for the oxidation of SO2 to SO3 is not V2O5 or even solid but rather molten mixture of
alkali metal and vanadyl sulfates/pyrosulfates. The catalyst becomes solid as various deactivating compounds are formed.
