The adsorption and coadsorption of CO and H2 on polycrystalline Pt have been examined using temperature programmed desorption (TPD) and ion scattering spectroscopy (ISS). The data show that CO adsorbs molecularly through the C with the O pointing away from the surface and that the surface is about 80% covered. TPD data obtained after coadsorption indicate that a CO-H complex forms at this surface.
