摘要

本研究采用溶剂热法,用均苯三甲酸(H3BTC)与过渡金属Zn(Ⅱ)盐合成了一种新型的Zn(Ⅱ)-MOFs配合物[ZnBTC·DMF·CH3NH2CH3]n.晶体结构显示,该配合物属于单斜晶系中的P21/c空间群.均苯三甲酸中的羧基通过单齿和桥连的方式与Zn(Ⅱ)配位,形成了网格状的三维MOFs结构,游离的DMF分子和二甲胺离子填充于MOFs空隙中.光催化降解数据表明,在250W紫外灯的驱动下,该配合物作为催化剂能有效抑制亚甲基蓝、甲基橙、罗丹明B的光催化降解.

Abstract

A new novel Zn(Ⅱ)-MOFs material,namely[ZnBTC·DMF·CH3NH2CH3]n,was synthesized by solvothermal method using the ligands of H3BTC(H3BTC=benzene-1,3,5-tricar-boxylic acid)and the Zn(Ⅱ)salts.Single crystal X-ray diffraction analysis revealed that the complex crystallizes in the monoclinic crystal system of the P21/c space group.The carboxyl group of benzene 1,3,5-tri-carboxylic acid adopts monodentate and bridge-dentate mode to coordinate with Zn(Ⅱ)cations,forming a netlike 3D MOFs structure.The free DMF molecules and dimeth-ylamine cations were filled in the voids of MOFs.Photocatalytic degradation data revealed that the complex acts as a catalyst to inhibit the degradation of meth-ylene blue,methyl orange and rhodamine B under a 250W ultraviolet lamp.
