The Oxidation of Methanol on Cr₂O₃ (101̅2) Single Crystal Surfaces
… and nucleophilic from lattice oxygen to form dioxymethylene. Hydrogenation of methoxides leads to the formation of CH₄ and CH₃OH above 550 K. Formate is formed as a surface intermediate by reversible dehydrogenation of dioxymethylene. Formaldehyde is produced via C-O bond cleavage of …

Reaction chemistry of C₁ hydrocarbon fragments and oxygenates on Cr₂O₃ (101̅2)
… spectroscopy. Adsorbed formaldehyde forms dioxymethylene species on the nearly-stoichiometric surface that react primarily above 600 K. Dioxymethylene decomposes via a Cannizzaro-type process with dehydrogenation to formate, and hydrogenation to methoxide. Methoxide hydrogenation produces …
