摘要

以柔性配体1,4-二(2-甲基咪唑-1-基)丁烷(bib)、过渡金属Co(Ⅱ)盐和1,3-金刚烷二甲酸(H_2ada)为原料,采用水热合成法合成配位聚合物[Co(bib)(ada)]_n.用X射线单晶衍射仪测定了配合物的晶体结构,并对其进行红外和紫外等性质表征,重点探究了其在催化降解甲基橙方面的应用和机理.结果表明,配合物属单斜晶体,P2/n空间群.催化实验结果表明,在紫外灯光照下[Co(bib)(ada)]_n对甲基橙有较好的降解效果.
        The coordination polymer[Co(bib)(ada)]_nwas synthesized by hydrothermal method with flexible ligand 1,4-bis(2-methy limidazol-1-yl)butane,the transition metal cobalt salt and acid(H_2ada).The structure of the compound was determined by single-crystal X-ray diffraction.The properties of IR and UV were also characterized.The photocatalytic activity and the mechansim were investigated mainly.The results showed that the complex belongs to monoclinic crystal,P2/n space group.The results of catalytic experiments indicated that[Co(bib)(ada)]_nhas a good degradation effect on methyl orange under ultraviolet light.
