dc.description.abstractThe adsorption and oxidation of n-propyl alcohol on Pt and Pt modified with saturated adsorped Sb and S (Pt/Sb-ad and Pt/S-ad) electrodes were studied using cyclic voltammetry and electrochemical quartz crystal microbalance (EQCM). The results demonstrated that the oxidation of n-propyl alcohol depends strongly on the oxidation states of the electrode surface. Sb adatoms on Pt surface can adsorb oxygen at relatively low potentials, and exhibit catalytic effects for n-propyl alcohol oxidation. In comparison with n-propyl alcohol oxidation at a Pt electrode, the oxidation peak potential of n-propyl alcohol on Pt surface modified with saturated Sb-ad was negatively shifted about 290 mV and the peak current was doubly increased. In contrary, the oxidation of S adatoms consumes oxygen species of Pt electrode surface. Consequently, the oxidation of n-propyl alcohol was inhibited on Pt surface modified with Sb-ad in saturation. The EQCM studies provided quantitative results of surface mass changes during n-propyl alcohol oxidation, and have thrown new light in elucidating different effects of adatoms Sb-ad and S-ad on Pt electrode surface towards n-propyl alcohol oxidation.zh_CN
