摘要：

We have studied the oxidation of carbon monoxide (CO) on an oxygen-precovered gold (1 1 0)-(1 x 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 10) is reported. (C) 2004 Elsevier B.V.
