Abstract
According to the structure/property characteristics of polyacids, the design and synthesis of new inorganic organic hybrid materials based on POMs is of great significance for the rapid and effective removal of pollutants in wastewater. In addition, many researchers have synthesized a large number of POMs-based inorganic organic hybrid compounds with organic cations as templates. Based on the above background, in this article, a new supramolecular compound named o-[C20H18N2O4][Mo8O26]0.5.H2O was obtained through hydrothermal method by reacting 1, 2-bis[4-nitrile-pyridine)-N-methylene]phenyldibromide (L1) with (NH4)6Mo7O24.4H2O. The compound was characterized by IR, PXRD, and single crystal X-ray analysis. Single crystal X-ray analysis shows that the compound consists of a [β-Mo8O26] 2–, a dicarboxylic acid chelating ligand and a water molecule. This compound exhibits good catalytic activity towards MB. The degradation rate of MB by photocatalysis of compound 1 was 75.2% . The novelty of this work lies in the synthesis of a cyano-hydrolyzed ligand and the high efficiency of MB degradation of the compound.
