| Abstract: | Under the applied high reaction temperatures ( 900 K) the Ag surface is restructured and a tightly held oxygen species is formed on the surface (O ) apart from O atoms dissolved in the bulk (O ). Methanol oxidation to formaldehyde proceeds through this O species as demonstrated by application of a variety of spectroscopic techniques. |
