The planar, continuous β-Mo2C sample was prepared by temperature-programmed carburization of pure molybdenum foil. We review our results showing selective deoxygenation of cyclobutanone, cyclopentanone, cyclohexanone, acetone and acetaldehyde to form coadsorbed alkylidene and atomic oxygen species on the metal carbide. RAIRS measurements were used to detect surface oxo species. Olefin metathesis reaction steps were used to detect surface alkylidene species. The selective deoxygenation activity of the β-Mo2C foil is related to the C/Mo ratio at the surface.
