Abstract
Pt group metals have been widely used in catalysis such as hydrogenation of organic compounds and the oxidation of carbon monoxide. The information about CO adsorption on the Pt group surfaces and the influence of other surface species, such as hydrogen and CO2 will be greatly helpful to elucidate the adsorption behavior of CO on Pt group metal surfaces and get a deeper understanding of catalytic mechanisms of Pt group metals. Surface enhanced Raman spectroscopy (SERS) has been becoming an increasingly important means to characterize the electrochemical metal solution interface over the past two decades. Our laboratory has successfully obtained SERS from neat transition metal surfaces, including Pt, Ni, Feand Co. We are able to observe the SERS of CO and the atop adsorbed H on roughened Pt surfaces. However, compared with Ag, Au and Cu which exhibit great surface enhancement, the weak enhancement of the transition metals make it unsuitable for the detailed study for those adsorbates with very small Raman scattering cross sections.
