Abstract

Reflection absorption infrared spectroscopy (RAIRS) has been used to investigate the adsorption of CO on CeO2-x-supported Pd nanoparticles at room temperature. The results show that when CeO2-x is initially grown on Pt(I 11), a small proportion of the surface remains as bare Pt sites. However, when Pd is deposited onto CeO2-x/Pt(I 11), most of the Pd grows directly on top of the CeO2-x(111). RAIR spectra of CO adsorption on I ML Pd/CeO2-x/Pt(I 11) show a broad CO-Pd band, which is inconsistent with a single crystal Pd surface. However, the 5 ML and 10 ML Pd/CeO2-x/Pt(I 11) spectra show vibrational bands consistent with the presence of Pd(I 11) and (100) faces, suggesting the growth of Pd nanostructures with well defined facets.
