Abstract

The invention discloses a preparation method and application of nitrogen-containing defect site porous carbon based on a microporous organic polymer. According to the preparation method, a C-N coupling reaction is used for polymerizing a central carrier and a linker under the action of salt to obtain a nitrogen-containing microporous organic polymer precursor capable of being carbonized. Under the action of a gas atmosphere template, the microporous organic polymer is directly carbonized as a precursor, the specific surface area and the pore channel structure of the microporous organic polymer are regulated and controlled by regulating and controlling different charcoal burning temperatures, and finally the nitrogen-containing defect site porous carbon material based on the microporous organic polymer is obtained. The method has the advantages of simplicity in operation, mild conditions, remarkable effect, greenness, environmental protection and the like, the porous carbon can be prepared without any complex operation, and the nitrogen-containing defect site porous carbon prepared based on the microporous organic polymer can effectively improve the CO2 adsorption capacity, and is suitable for large-scale production. Therefore, the method has a wide application prospect.

Description

technical field [0001] The invention belongs to the field of synthesis of chemical functional materials, and in particular relates to the preparation of nitrogen-containing defect-site porous carbon based on microporous organic polymers and its application in carbon dioxide adsorption. Background technique [0002] Porous carbon materials refer to a class of solid materials containing a certain number of interconnected or closed pores and the medium is carbon. Porous carbon materials have high chemical stability, good electrical conductivity, good biocompatibility, and low price. At the same time, they also have the characteristics of high specific surface area, adjustable pore size, controllable pore structure, and easy modification. Therefore, porous carbon materials have been widely used in the fields of gas adsorption and separation, water treatment, catalysis, and energy storage. At present, most of the methods for preparing porous carbon materials use small organic mo...
