[0042] (1) Powder diffraction characterization of phase purity

[0043] The PXRD diffraction pattern of compound 1 is as follows figure 1 As shown, the positions of the key diffraction peaks measured in the experiment match the positions of the key diffraction peaks calculated theoretically, which indicates that compound 1 has a high purity and is a single phase. The difference in the intensity of the diffraction peaks may be due to the variation of the preferred orientation of the powder during the experimental data collection.

Abstract

The invention discloses a polyacid compound with metal bridging and a multi-dimensional structure. The polyacid compound is obtained in the mode that ammonium molybdate, organic ligands and metal saltare subjected to a heat seal reaction in a solvent, namely an alcoholic solution, wherein the ammonium molybdate is (NH4)6Mo7O24 4H2O, the organic ligands are ethidene diamine or (1R,2R)-1,2-diphenylethylenediamine, and the metal salt is copper salt. A preparation method of the polyacid compound with metal bridging and the multi-dimensional structure is simple, the capacity of catalyzing organicdyestuff is high, and good dirt and rust removing cleaning effects are achieved. The polyacid compound can be used as a light degradation catalyst for organic pollutants in waste water, and has good application prospects in the technical fields of material science and waste water treatment.

Description

technical field [0001] The present invention relates to the field of polyacid compounds. More specifically, the present invention relates to a metal-bridged polyacid compound with a multidimensional structure and its application. Background technique [0002] Polyacids are important research objects in inorganic chemistry. The scientific name is polyoxometalates (polyoxometalates, POMs) or metal-oxygen clusters (metal-oxygen clusters), which are mainly compounds obtained by condensation of inorganic oxoacid ions. , According to the presence or absence of heteroatoms, it can be divided into isopolyacid compounds (such as hexamolybdic acid) and heteropolyacid compounds (such as phosphotungstic acid). The elements that can be used as coordination atoms in polyacid compounds mainly include Mo, W, Nb, etc., and there are nearly 70 elements that can be used as heteroatoms, so polyoxometalates have the characteristics of many types and complex structures. In recent years, selecti...
