Molecular sieves refer to a class of substances with uniform micropores and the pore size is equivalent to the general molecular size. Molecular sieves are widely used and can be used as high-efficiency desiccants, selective adsorbents, catalysts, ion exchangers, etc. However, the cost of using chemical raw materials to synthesize molecular sieves is very high. Commonly used molecular sieves are crystalline silicates or aluminosilicates,
