摘要
Abstract
A new inorganic-organic hybrid[(H3DIBA)2Cl]·[HGeMo12 O40](HDIBA=3,5-bis(1H-imidazol-1-yl)benzoic acid)based on Keggin-type polyoxometalate anion was synthesized by hydrothermal synthesis,in which HDIBA was a tridentate organic ligand containing two imidazole and one carboxyl groups.The results showed that the compound is triclinic,space group P-1,a=1.27831(4)nm,b=1.29723(4)nm,c=1.98978(5)nm,α=94.51°,β=102.61°,y=117.99°,V=2.77968(14)nm3,and Z=2.The HDIBA in the compound is protonated,and a one-dimensional supramolecular chain is formed by hydrogen bonding interactions between the organic ligand and free Cl-.There are hydrogen bonding interactions between[GeMo12O40]4-polyoxoanions and[H3DIBA]2+,which connect the adjacent one-dimensional supramolecular chains into a three-dimensional supramolecular structure.The compound can degrade the organic dye Malachite green by photocatalysis,and the degradation rate reaches 99.99％in 150 min.In addition,electrochemical studies found that the compound has the properties of electrocatalytic reduction of BrO3-and electrocatalytic oxidation of ascorbic acid.In brief,the compound is an effective heterogeneous photocatalyst and electrocatalyst for the treatment of pollutants in wastewater.关键词
