Problems solved by technology
[0005] The synthesis of alkaline earth metal organic crystal materials mostly uses the hydrothermal synthesis method. Due to the different chemical substances selected, the different synthesis parameters, and the differences in the synthesis process, most of the synthesized substances have low purity and large differences in chemical and physical properties. It is difficult to meet the requirements of the synthesis process. Material requirements, so that the application of such materials has been greatly limited

The invention relates to a preparation method of an alkaline earth metal organic crystal material. According to the material, an alkaline earth metal barium nitrate is adopted as a metal source; 2,6-dimethylpyridin-3,5-dicarboxylic acid is adopted as an organic ligand; sodium hydroxide is adopted as a pH value regulating agent; and anhydrate ethanol and deionized water are adopted as solvents. A heating crystallization reaction is carried out in a reaction vessel, such that a crystallization reaction solution is prepared; and pump filtration, washing, and vacuum drying are carried out, such that metal organic crystals are prepared. The preparation method has the advantages of advanced process, detailed and accurate data, high preparation speed, and no environmental pollution. The product is transparent block-shaped crystals with a two-dimensional layered structure. The product has high purity reaching 95.3%, and can be matched with various chemical substances. The method provided by the invention is an ideal method for preparing alkaline earth metal organic crystal materials.
Description
technical field [0001] The invention relates to a preparation method of an alkaline earth metal organic crystal material, which belongs to the technical field of preparation and application of organic metal materials. Background technique [0002] Metal-organic crystal materials have good structural tailorability and easy functional characteristics, which are unmatched by other materials. Metal-organic crystal materials have the characteristics of organic compounds and inorganic substances. got applied. [0003] The synthesis process of metal-organic crystal materials will directly affect the structural characteristics and properties of the material. For example, the coordination tendency of metal ions and the geometric configuration of organic ligands are decisive factors. Anions, organic or inorganic template molecules, solvents, and reactants The ratio and the pH value of the reaction system will also have an important impact. [0004] Metal ions are the basic component...
