摘　　要：在相对温和的反应条件下,利用简单的反应过程将CO_(2)固定,形成高附加价值的产物,是当前很受关注的一项科学技术挑战,其中环氧丙烷和CO_(2)的环加成反应是实现碳中性,固定CO_(2)的一条理想途径,CO_(2)的有效活化则是这个反应的前提。但目前关于实验的反应过程和机理仍然是有待解决的问题。因此,在本研究中,我们通过合成不同金属基底的MOFs材料,分别进行CO_(2)与环氧丙烷的加成反应,分析最有利于反应进行的催化材料。实验结果表明,UiO-66-NH2的催化效果最好。本研究为不同材料的CO_(2)环加成反应的设计和应用提供一些新思路。The use of simple reactions to immobilise CO_(2)under relatively mild reaction conditions to form high value-added products is a current scientific and technological challenge of great interest,where the cycloaddition of propylene oxide and CO_(2)is an ideal way to achieve carbon neutrality and immobilise CO_(2).The effective activation of CO_(2)is a prerequisite for this reaction.However,there are still open questions regarding the experimental reaction process and mechanism.Therefore,in this study,we prepare metal-organic frameworks(MOFs)materials with different metal centers for the addition reaction of CO_(2)with propylene oxide.The experimental results show that UiO-66-NH2 has the best catalytic effect.This study provides some new ideas for the design and application of CO_(2)cycloaddition reactions with different materials.
