Description

technical field [0001] The invention relates to the preparation of crystalline materials, in particular to a multifunctional zinc-based organic-inorganic hybrid material and its preparation method and application. Background technique [0002] As a class of advanced porous crystalline materials, metal-organic frameworks have shown rapid development in the past few decades, and have shown many potential applications in the fields of energy gas storage and environmental pollutant identification. In general, metal-organic frameworks are composed of metal nodes and organic ligands. Compared with metal nodes, organic ligands are more selective and designable. Scientists can use the method of organic synthesis to design various organic ligands containing different coordination atoms and polar functional groups to construct metal-organic framework materials. However, this method usually requires a long synthetic route and expensive synthetic reagents. Cost control is very unfavor...
