摘要
为克服环境友好型催化剂磷钨酸比表面积小的缺点,本文通过超声振荡法将Dawson型磷钨酸负载在氧化石墨烯表面,得到Dawson型磷钨酸/氧化石墨烯复合材料。利用FT-IR、SEM和XRD等手段对其进行形貌表征,并以环己烯合成反应为探针考察复合材料的催化性能。结果表明该复合材料具有缩短反应时间、减少催化剂用量和提高产率等优点。
In order to overcome the shortcoming of low specific surface area of environment-friendly catalysts-phosphotuogstic acid, Dawson-type phosphotungstic acid/graphene oxide composites were prepared loading Dawson-type phosphotungstic acid on graphene oxide surface by ultrasonic oscillation method. The morphology of the composites were characterized by FT-IR, XRD and SEM. The catalytic performance of the composites was studied by using cyclohexene synthesis as a probe. The results showed that the composites have the advantages of shortening the reaction time, reducing the amount of catalyst and increasing the yield.
