Compared with the background art, the mesoporous carbon material preparation method has obvious progresses, a small organic molecule is taken as a carbon source, a Na-K alloy is taken as a reducing agent, methylbenzene is taken as a solvent, the materials are stirred at the room temperature to prepare a reaction solution, the reaction solution is subjected to suction filtration, washing and vacuum drying to prepare a mesoporous carbon material, the process of the preparation method is advanced, the data are full and accurate, the preparation is fast, high-temperature calcination is not needed, the product is a black powder, the black powder has a mesoporous porous structure, the yield of the product is as high as 75.6%, the mesoporous carbon material can be matched with various chemical substances, and the preparation method is a quite ideal method for preparing the mesoporous carbon material.

Description

technical field [0001] The invention relates to a method for preparing a mesoporous carbon material, which belongs to the technical field of preparation and application of carbon materials. Background technique [0002] Mesoporous carbon materials have good structural adjustability and stability, which is unmatched by other materials. Mesoporous carbon materials have high specific surface area and large pore volume, and have been obtained in the fields of adsorption, catalysis, optics, and electricity. widely used. [0003] The synthesis method and process of mesoporous carbon materials will directly affect the structural characteristics and properties of the material. For example, the choice of template and precursor is the decisive factor. The reaction temperature, solvent, ratio of reactants, pH value of the reaction system, roasting Temperature can also play an important role. [0004] Templating agent is the basic component of synthesizing mesoporous carbon materials....

AI Technical Summary

Problems solved by technology

[0005] In the process of synthesizing carbon materials with organic small molecules or polymers as precursors, most of them need to be calcined and carbonized at high temperature under an inert atmosphere. Due to the different chemical substances selected, the different synthesis parameters, and the differences in the synthesis process, the carbonization temperature ranges from 600 ° C to At 1800 °C, the chemical and physical properties of the obtained carbon materials are quite different, and it is difficult to meet the requirements of synthetic substances, which greatly limits the application of such materials
