FORMATION AND DECOMPOSITION OF ACETATE INTERMEDIATES ON THE AG(110) SURFACE Academic Article

abstract

• The reactions of CH3COOH and CH3CHO with oxygen adsorbed on a Ag(110) surface were examined by temperature-programmed reaction spectroscopy. Acetic acid reacted with surface oxygen to form H2O plus a stable acetate intermediate. Acetaldehyde reacted with surface oxygen to form CH3CHO2(ad) which decomposed at 250 K to liberate H2 and produce the stable acetate. The role of adsorbed oxygen in these two reactions was that of a strong base and strong nucleophile, respectively. The acetate intermediates formed by these two pathways were indistinguishable. The acetate intermediate decomposed near 640 K to produce CO2, CH3COOH, CH4, and H2CCO (and deposit small amounts of surface carbon). 1981.
