摘　　要：通过二氧化碳(CO_(2))与环氧化物的环加成反应可以将温室气体CO_(2)转化为有价值的化工产品环状碳酸酯,因而对该反应具有高效、高选择性的催化材料的开发一直是材料和催化领域研究的热点。UiO-66(University of Oslo,UiO)作为一种具有较高稳定性、较大开放性孔道的金属有机骨架材料(metal-organic framework,MOFs),在催化领域一直作为催化材料被广泛研究,但对于Lewis酸、碱催化的CO_(2)环加成反应,UiO-66通常需要在较为苛刻的反应条件下,或在离子液体类助催化剂或溶剂存在时才能展示出一定的催化效果。通过引入功能性基团、离子液体功能化、制造缺陷和与其他材料复合等手段可增加UiO-66框架的酸、碱位点含量,从而有效提高材料对CO_(2)环加成反应的催化性能。The greenhouse gas CO_(2)can be converted into valuable chemical product cyclic carbonate through the cycloaddition reaction of CO_(2)and epoxides.Therefore,the development of catalytic materials that can efficiently and selectively catalyze CO_(2)cycloaddition has been a hot topic in the field of materials and catalysis.As a highly stable MOFs with large open pores,UiO-66 has been widely studied as catalytic materials in the field of catalysis.However,for the CO_(2)cycloaddition reaction catalyzed by Lewis acid and base,UiO-66 shows a certain catalytic effect usually under relatively harsh reaction conditions,or in the presence of ionic liquid catalysts or solvents.The amount of acidic and basic sites in UiO-66 framework can be increased by introduction of functional groups,ionic liquid functionalization,defect-engineered and formation of composites with other materials,thereby the catalytic performance of UiO-66 for CO_(2)cycloaddition can be improved effectively.
