| 摘 要： | 基于氢键给体、阴离子和胺协同催化CO_2环加成反应的设计思想,以廉价、无毒、富含三级胺的六次甲基四胺为前驱体,采用原位固载的方法制得了硅羟基、季铵盐和三级胺功能化的氧化石墨烯(GO)。随后,利用正溴丁烷进一步季铵化合成多阳离子季铵盐功能化的GO(F-GO)无金属多相催化剂。采用红外光谱、元素分析和光电子能谱分析了催化剂表面的组成和含量,证明多阳离子化的策略有利于提高GO表面离子液体的固载量,所制备的F-GO表面季铵盐和三级胺负载量分别为2.23和2.49mmol·g~(-1)。F-GO在无溶剂和无助剂条件下可高效催化CO_2和环氧丙烷环加成反应,碳酸丙烯酯收率可达99.2%(100℃,2 MPa,4 h)。此外,F-GO材料具有较好的耐水性和稳定性,循环6次后活性几乎不变。
