摘要：

Previous temperature programmed desorption (TPD) studies [1,2] have concluded that formaldehyde desorption is the only significant pathway in methanol oxidation at Cu(110) surfaces. We show that this is true only under a limited range of experimental conditions, and in fact formate production is often the more favourable reaction pathway. This has important implications for other systems that have been discussed where it has been assumed that the formate formation pathway on copper is unfavourable.
