Abstract

The adsorption of carbon monoxide on a platinum-rhodium alloy (111) single crystal surface was studied with a combination of reflection absorption infrared spectroscopy, thermal desorption spectroscopy, and work function change measurements. It was found that CO shows a pronounced preference for adsorption on Rh sites both at 100 K and room temperature, up to a coverage at which available next-nearest neighbor Rh sites were filled. Adsorption was found to be predominantly in atop sites and only weak bridge bands were detected at 100 and 300 K. (C) 1997 American Vacuum Society.
