Abstract
The adsorption and coadsorption of CO and H-2 on polycrystalline Pt ha ve been examined using temperature programmed desorption (TPD) and ion scattering spectroscopy (ISS). The data show that CO adsorbs molecula rly through the C with the O pointing away from the surface and that t he surface is about 80% covered. TPD data obtained after coadsorption indicate that a CO-H complex forms at this surface.
