Reactions of H2PtCl6 on HY Zeolite

Abstract The reactions of H 2 PtCl 6 supported on HY zeolite were studied by X-ray photoelectron spectroscopy and diffuse reflectance spectroscopy. During impregnation, [PtCl 6 ] 2− is anchored on the surface via chloride bridging. On the basis of the spectroscopic results, the feature of the thermal decomposition of H 2 PtCl 6 on HY zeolite may be represented as follows: where the subscript s denotes surface. The decomposition reactions are different from those of the unsupported compound as a result of interaction between the complex and the support.
