Abstract

CO chemisorption on PVP-protected Pt clusters supported on fine high silica zeolite Beta has been studied by in situ FTIR spectroscopy. Two special CO adsorption bands are observed at 2050 cm-1 and 1860 cm-1, respectively, on the surface of catalysts. The frequency shifts and CO band intensity vary with the changing of catalyst preparation parameters, such as polymer amount, Pt loading and pretreatment processing. The results show that PVP-protected Pt clusters have high dispersion on Beta zeolite surface and strong chemical adsorption to CO.
