| Abstract: | he oxidation of glycol on electrolytic silver catalyst has been studied by using ultrahigh vacuum temperature-programmed-reaction troscopy (TPRS) and transient response method. It was found that glycol could be adsorbed on the surface of electrolytic silver at room temperature and gave a group of products at 343 K. Reaction of glycol with preadsorbed oxygen gives three groups of product at 343, 433 and 612K, respectively. The catalytic activity and selectivity of electrolytic silver for this reaction have been measured. Based on the experimental results, a reaction mechanism was proposed. |
