摘要

Developing new catalysts for highly selectivity and conversion of saturated C(sp3)-H bonds is of great significance.In order to obtain catalysts with high catalytic performance,six Eu-based MOFs with different structural characteristics were obtained by using europium ions and different organic acid ligands,namely Eu-1～Eu-6.Eu-1,Eu-2 and Eu-3 featured three-dimensional structures,while Eu-4 and Eu-5 featured two-dimensional structures.Differently,a one-dimensional chain structure of Eu-6 was obtained by changing the ligand.All the six MOFs were applied to the catalytic reaction of C(sp3)-H bond,and it was found that the catalytic effect was gradually en-hanced with the decrease of dimension and the increase of the size of channels.As expected,Eu-6 showed the highest selectivity(～99％)and conversion(～99％).Moreover,catalytic cycling and stability tests showed Eu-6 can be a reliable catalyst.
