Abstract
We report measurements of CO oxidation by CO molecular beam titration of an Ir (110) surface precovered with atomically bonded oxygen. The C O2 formation rate increases with increasing CO fluence and depends str ongly on both oxygen precoverage and surface temperature. The self-acc elerating CO2 formation kinetics may be qualitatively discussed in the framework of coverage-dependent kinetics of the Langmuir-Hinshelwood type. (C) 1998 American Vacuum Society.
