AbstractThe adsorption and decomposition of acetic acid on SmOx/Rh ( 100) model surface were investigated with high resolution electron energy loss spectroscopy (HREELS) and thermal desorption spectroscopy (TDS). The presence of SmOx weakened O-H bond in acetic acid molecules and therefore facilitated the formation of adsorbed acetate at 120 K. Increasing the temperature, the addition of SmOx promoted further the decomposition of adsorbed acetate by weakening C-C bond. Upon adsorption on SmOx/Rh(100) surface at 120 K, most acetic acid molecules produced adsorbed acetate species via O-H bond cleavage. When the sample was heated to about 225 K, the decarboxylation of acetate occurs and CO is the main product. The CO and H, peaks were also observed at 417 K and 477 K, which could be attributed to reaction-limited products. The reaction mechanism was also discussed in this paper.
