摘　　要：以硝酸铁和均苯三酸为原料,采用水热方法合成了金属有机骨架材料MIL-100(Fe),并采用不同浓度的己二胺乙醇溶液进行后修饰,制备得到氨基化的金属有机骨架材料MIL-100(Fe)-NH2。利用X射线衍射(XRD)、傅里叶变换红外光谱(FT-IR)、扫描电镜(SEM)和透射电镜(TEM)等技术对MIL-100(Fe)-NH2材料的结构和形貌进行了表征。以苯甲醛和氰基乙酸乙酯的Knoevenagel缩合反应为模型反应,考察了MIL-100(Fe)-NH2作为固体碱催化剂的催化性能和循环稳定性。研究结果表明,采用低浓度的修饰剂可以制备结构保持的氨基功能化材料MIL-100(Fe)-NH2。该材料能够快速催化苯甲醛和氰基乙酸乙酯的Knoevenagel缩合反应,而且可以循环使用至少4次而没有明显活性损失。Metal organic frameworks MIL-100（Fe）was prepared using iron（Ⅲ）nitrate nonahydrate and trimesinic acid by a solvothermal method,which was then surface modified with hexamethylene diamine ethanol solution with various concentration.The structure and morphology of material were characterized by XRD,FT-IR,SEM and TEM techniques.Knoevenagel condensation between benzaldehyde and ethyl cynoacetate was selected as a model reaction to investigate their catalytic performances.Results indicated that MIL-100（Fe）-NH2 not only could promote the knoevenagel condensation efficiently,but also could be recycled at least four times without obvious loss of its catalytic performance.
