Method for preparing mesoporous material through microwave-assisted loading of nanometer silver oxide

Abstract

The invention discloses a method for preparing mesoporous material through microwave-assisted loading of nanometer silver oxide. The method specifically includes the first step of preparing a solution A, the second step of preparing a solution B, the third step of carrying out primary dipping, the fourth step of carrying out deep dipping, and the fifth step of preparing the finished product. According to the method, granules containing Zn and Ag and the graphite oxide component are attached to the surface of the mesoporous material through microwave ultrasonic loading, metal ions and graphite oxide form a double-layer structure on the surface of the mesoporous material, the loss rate of graphite oxide is low, and thus cost is reduced; by the adoption of microwave-assisted loading, the method has the advantages that reaction conditions are mild, the reaction speed is high, and the yield is high; the pH value is regulated to be 5-6 with a hydrogen chloride solution, the loading capacity of metallic oxide is improved, and the dispersity of metallic oxide is good; a titanium dioxide catalyst is sprayed on the surface of the mesoporous material blow-dried with nitrogen, integration of the mesoporous material and the surface-loaded material is achieved, and the titanium dioxide catalyst is high in loading efficiency, makes the polymerization process easy to control, accelerates the reaction process and improves productivity.

Description

Technical field [0001] The invention belongs to the technical field of improved methods for mesoporous materials, and specifically relates to a method for preparing mesoporous materials by microwave-assisted loading nano-silver oxide. Background technique [0002] Mesoporous materials have the characteristics of extremely high specific surface area, regular and ordered pore structure, narrow pore size distribution, and continuously adjustable pore size, which make it difficult to complete the adsorption and separation of macromolecules in many microporous zeolite molecular sieves, especially Play a role in catalytic reactions. Therefore, since its birth, mesoporous materials have attracted a wide range of international interest in multidisciplinary research fields such as physics, chemistry, biology, materials and information, and have become one of the hot frontiers of interdisciplinary in the world. [0003] The most commonly used synthesis method is hydrothermal synthesis, and ...

Problems solved by technology

[0004] Due to the large amount of MAO required to achieve high activity of the mesoporous materials loaded with metal catalysts, the production cost is high, and the obtained polymer has no particle shape, which cannot be used in the widely used slurry or gas phase polymerization process. An effective solution to the problem is to load the soluble metallocene catalyst
