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.

一种由溴盐和β-Mo8O26 阴离子得到的有机-无机化合物的合成、表征和光催化性能

根据多元酸的结构/性质特点，设计和合成基于 POMs 的新型无机有机杂化材料对于快速有效地去除废水中的污染物具有重要意义。此外，许多研究人员以有机阳离子为模板合成了大量基于 POMs 的无机有机杂化物。基于上述背景，本文通过水热法将 1, 2-双[4-腈-吡啶)-N-亚甲基]苯基二溴化物（L1）与 (NH4)6Mo7O24.4H2O 反应，得到了一种新的超分子化合物，命名为 o-[C20H18N2O4][Mo8O26]0.5.H2O。该化合物通过红外光谱、PXRD 和单晶 X 射线分析进行了表征。单晶 X 射线分析表明，该化合物由一个 [β-Mo8O26] 2-、一个二羧酸螯合配体和一个水分子组成。这种化合物对甲基溴具有良好的催化活性。通过化合物 1 的光催化作用，甲基溴的降解率为 75.2%。这项工作的新颖之处在于合成了一种氰水解配体，而且该化合物对甲基溴的降解效率很高。
