ZMS-5 zeolite modified with Nb was investigated by XRD, IR and MAS NMR spectroscopies. Niobium atoms were introduced by calcination of NH4ZSM-5 zeolite with Nb2O5. The last samples showed Broensted and Lewis acidity and can catalyse m-xylene ammoxidation to nitriles. Thermal treatment of ZSM-5 and Nb2O5 decreases the amount of aluminium atoms eliminated from the lattice and preserves the framework.
