双吡啶双酰胺配体构筑的钴配合物的合成、结构及光催化性能研究
Synthesis,Structure and Photocatalytic Properties of a Cobalt Complex Constructed by Dipyridyl-Diamide Ligand
摘要
Abstract
In this paper,a semi-rigid dipyridyl-diamide ligand was selected as the organic linker to assemble with CoCl2,and a new cobalt complex[Co(EDPB)Cl2](EDPB=(E)-4,4'-(ethene-1,2-diyl)bis(N-(pyridin-3-yl)benzamide))was prepared under the solvothermal conditions.The structure and properties of the complex were tested by single crystal X-ray diffraction,powder X-ray diffraction,infrared spectra,thermogravimetric analysis,and solid-state UV-Vis diffuse reflectance spectra.It is found that the Co(Ⅱ)atoms in the complex are tetracoordinated,which connect with EDPB ligands to form a 1D chain structure.The complex exhibits excellent absorption for visible light and highly heterogeneous catalytic activity for Cr(Ⅵ)reduction reaction with 97.9％of reduction rate in 60 min.The complex's ability to be recycled for photocatalytic Cr(Ⅵ)reduction reaction was examined.Remarkably,it can be reused at least five times without any degradation in activity,showing its excellent cycling stability.关键词
