About the cover

The cover image shows the gold electrode used by Rodriguez, Kwon and Koper in their study of gold-catalysed alcohol oxidation. The electrode is in the 'hanging-meniscus configuration' and is immersed in an aqueous solution. When modified with carbon monoxide, the gold surface catalyses the oxidation of certain alcohols in alkaline media. Remarkably, the carbon monoxide acts as a reaction promoter, in contrast to its usual role as a poison.
