Water has important effects on several reactions occurring over gold catalysts. In this work, we review studies demonstrating the interactions of water in surface chemistry and catalysis over gold, with specific emphasis on the ability of water to enhance activity for the CO oxidation reaction and the role water plays in the mechanism of the water–gas shift reaction. Water significantly influences...
This paper presents results of an investigation of low-temperature CO oxidation and the role of moisture on an atomic oxygen covered Au(111) surface by employing molecular beam scattering techniques under ultrahigh vacuum (UHV) conditions. The effect of atomic oxygen precoverage on CO oxidation was examined at sample temperatures as low as 77 K. Prompt CO2 production was observed when the CO beam...
