Abstract
Pt-Cu/HZSM-5 catalysts with various Cu/Pt ratios are studied by EXAFS/ XANES, XPS/XAES, IR spectroscopy of adsorbed CO, and electron microsco py after oxidation-reduction treatment. The data obtained reveal bimet allic alloy particles in the zeolite matrix. The structure of these pa rticles is found to be dependent on their composition and pretreatment conditions.
