Popis: We have studied the oxidation of carbon monoxide (CO) on an oxygen-precovered gold (1 1 0)-(1 × 2) surface. At low oxygen coverages, the reaction is first-order in the oxygen coverage and has an apparent activation energy of −1.8 kJ/mol. Assuming a Langmuir–Hinshelwood mechanism we evaluated a true activation energy of 57 kJ/mol. A complete reaction energy diagram of the CO oxidation on Au(1 1 0) is reported.
