Novel synthesis of a vanadium–titanium aluminophosphate molecular sieve of MFI structure (VTAPO-5) and catalytic activity for the partial oxidation of methanol

Abstract

A new vanadium–titanium substituted aluminophosphate molecular sieve of MFI structure (VTAPO-5) was synthesized hydrothermally and found to be active and selective in partial oxidation of methanol; catalytic activity depends on the vanadium sites; however, the presence of titanium influences the reactivity of vanadium species during reaction.
