摘要
用热脱附、程序升温反应谱和瞬时应答对丁醇在电解银上的氧化反应进行了研究。结果表明,室温下丁醇在电解银表面轻微吸附,氧能促进丁醇的吸附并在363K、461K和626K处给出三组产物的脱附峰,对应于不同的表面反应。根据实验结果,提出了丁醇在电解银表面的氧化反应机理。
The oxidation of n-Butanol on electrolytic silver catalyst has been studied using a ultra-high vacuum temperature—programmed-reaction-spectroscopy (TPRS) and a transient response method. It was found that n-Butanol can adsorb on the surface of electrolytic silver slightly at room temperature and desorbed at 362K. Reaction of n—Butanol with preadsorbed oxygen give three groups of products at 363K, 461K and 612K, respectively. Based on our experimental results, a reaction mechanism was proposed.
