Title:

METHOD FOR PREPARING POROUS CARBON STRUCTURE HAVING INCREASED SURFACE AREA AND TOTAL PORE VOLUME, AND POROUS CARBON STRUCTURE PREPARED USING SAME

Document Type and Number:

WIPO Patent Application WO/2022/220451

Kind Code:

A1

Abstract:

Disclosed are: a method for preparing a porous carbon structure, capable of dramatically increasing the surface area and total pore volume of the porous carbon structure; and a porous carbon structure prepared using same. The method of the present invention comprises the steps of: preparing a template having a mesoporous shell; injecting a carbon precursor into the template, the carbon precursor comprising a polymer precursor and a cross-linking agent, the polymer precursor comprising a first component, which has a halogen functional group, and a second component, which does not have a halogen functional group, and the amount of the first component in the polymer precursor being 20-80 wt%; polymerizing the polymer precursor to form a polymer; carbonizing the polymer to obtain a template-carbon complex; and removing the template from the template-carbon complex.
