摘要：

The adsorption and surface diffusion of CO on Pd/W (110) and Cu/Rh (100) surfaces have been studied using infrared reflection-absorption spectroscopy (IRAS). For CO adsorbed on 0.14 MP Pd on W (110), the CO is found to diffuse from Pd to W at approximately 200 K. Likewise, CO adsorbed on ≈ 0.1 ML Cu on Rh (100) will diffuse from the Cu to the Rh at approximately 250 K. In addition, the CO adsorbed on the copper is blue-shifted relative to the gas phase CO stretching frequency of 2143 cm-1. © 1990.
