Preparation method of ordered mesoporous carbon material

Abstract

The invention discloses a preparation method of an ordered mesoporous carbon material, wherein the method comprises the steps: 1) at room temperature, placing a structure-directing agent and a carbon precursor in a reactor; 2) at the temperature of 50-350 DEG C, carrying out heat treatment for 10-720 minutes; and 3) roasting the product obtained in the step 2) at the temperature of 400-800 DEG C and in an inert atmosphere, and thus obtaining the ordered mesoporous carbon material. The method for direct heating of solid mixtures is adopted, while the structure-directing agent, the carbon precursor and a functionalized precursor are subjected to molecular-level self-diffusion balance, the self-assembly process is completed, and then the ordered mesoporous carbon material or functionalized mesoporous carbon material is obtained through roasting; therefore, mechanical grinding and the separation problem between a mesoscopic-phase intermediate and equipment due to grinding are completely avoided, the operation is simplified, the cost is reduced, and the synthesized mesoporous carbon material has good mesoscopic orderliness and larger specific surface area and pore volume.

Description

technical field [0001] The invention relates to a mesoporous carbon material, in particular to a preparation method of an ordered mesoporous carbon material. Background technique [0002] Ordered mesoporous carbon materials have large specific surface area and pore volume, regular pore structure, high hydrothermal stability and mechanical strength, so they have a wide range of applications in adsorption and separation, catalyst supports, bioreactors, electrode materials, etc. , further modifying its channels and surface can also endow it with special functions. [0003] At present, the synthesis of ordered mesoporous carbon materials mainly adopts hard template method and soft template method. The preparation process of the hard template method includes: pre-preparing the carrier, introducing the carbon precursor, and finally removing the carrier. This method is cumbersome, time-consuming, resource-wasting and costly. The soft template method overcomes the cumbersome and ...

Problems solved by technology

Although this method avoids the use of solvents and reduces the synthesis cost, it still needs to use mechanical equipment to grind the polymer monomer and surfactant into a paste-like mesoscopic intermediate, which will not only increase equipment investment, but also exist The difficulty of separating the paste from the mechanical equipment will also increase the cost of later operations
