Atomic oxygen adsorbed on metallic gold promotes the low-temperature transformation of methanol to methyl formate, formaldehyde, and formic acid. The reactions occur with oxygen-containing gold nanoparticles (ca. 2 nm in diameter), which form when Au(111) is oxidized with ozone. The detailed reaction mechanism is discussed by C. M. Friend and co-workers in the Communication on page 4206 ff.
