ZSM-5 zeolite modified with Tl has been investigated with XRD, IR and XPS spectroscopies. Thallium Tl(+) ions were introducted in the exchange reaction in water medium, accompanied by exchange of Na(+) with H(+). From XPS results follows that more likely thallium atoms have been incorporated to the ZSM-5 zeolite lacctice as Tl(+) species. All TlHNa-ZSM-5 zeolite samples catalyzed ammoxidation of m-xylene. X-ray diffractograms before and after ammoxidation proved the preservation of the ZSM-5 zeolite structure.
