Disclosed are: a method for preparing a porous carbon structure capable of significantly increasing the surface area and the total pore volume of the porous carbon structure; and a porous carbon structure prepared using the method. The method comprises the following steps: preparing a template with 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 having a halogen functional group and a second component not having a halogen functional group, and the content of the first component in the polymer precursor being 20 to 80 wt%; polymerizing the polymer precursor to form a polymer; carbonizing the polymer to obtain a template-carbon composite; and removing the template from the template-carbon composite. 公开了一种制备多孔碳结构的方法，其能够显著增加多孔碳结构的表面积和总孔体积；和使用所述方法制备的多孔碳结构。本发明的方法包括如下步骤：制备具有介孔壳的模板；将碳前体注入到所述模板中，所述碳前体包含聚合物前体和交联剂，所述聚合物前体包含具有卤素官能团的第一组分和不具有卤素官能团的第二组分，并且所述第一组分在所述聚合物前体中的含量为20
