摘要
制备和考察了一系列银催化剂、金催化剂和银-金双金属催化剂,通过系列结构表征及其在丙烯直接环氧化制环氧丙烷反应中的性能评价研究,发现单金属银催化剂对目标产物的选择性较低,而双金属催化剂能够显著提高反应选择性,在丙烯直接环氧化反应中表现出良好的应用潜力。
In this study, a series of silver catalysts, gold catalysts and Ag-Au bimetallic catalysts were prepared. The structure characteristics were investigated by series of characterizations and their catalytic performances were evaluated by the direct epoxidation of propylene to produce propylene oxide. It was found that the selectivity of monometallic silver catalyst to the target product was very low, while the bimetallic catalyst could significantly improve the selectivity of the reaction and showed good application potential in the direct epoxidation of propylene.
