Abstract

The invention discloses a silver coordination polymer. The chemical formula of the silver coordination polymer is C24H20AgN4O2, 4,4'-di(parazole-1-methyl)-biphenyl is taken as the major ligand, terephthalic acid is taken as the auxiliary ligand, distilled water is taken as the solvent, the microwave heating reflux synthesis method is adopted, the first binode two-dimensional '4,4L10' topological network structure is formed, sufficient representation of the structure is achieved through elemental analysis, thermogravimetry and a single crystal X-ray diffractometer, and the luminescent property and degradation property on methyl orange dye of the structure are researched in detail too. The preparing process is simple, the yield and purity of crystals are high, high thermal stability and special luminescent property are realized, organic pollutants can be degraded through Fenton-like reaction, degradation efficiency is high, and the silver coordination polymer can serve as a catalyst and has great application prospects in the field of luminescent materials and environment protection.

Description

technical field [0001] The invention relates to a metal-organic coordination polymer material and its preparation and application, in particular to a silver coordination polymer and its preparation method and application. Background technique [0002] Metal-organic coordination polymers have attracted the attention of chemists due to their fascinating topological structures and great potential value in the fields of catalysis, luminescence, gas storage, molecular magnetism, ion exchange, etc. In view of the shortcomings of organic pollutants that are difficult to decompose naturally and have a long decomposition cycle, the application of coordination polymer catalytic materials to the degradation of organic pollutants has attracted widespread attention, and has become a green, stable and efficient environmental restoration method . In addition to using multidentate ligands and symmetric ligands to construct multidimensional spatial structures through covalent bonds, low-dim...
