Method for preparing porous carbon material and porous carbon material obtainable by same
Known methods for preparing a porous carbon material with a hierarchical porosity comprise the steps of a) providing at least one carbon source and at least one amphiphilic species, b) combining the carbon source and the amphiphilic species to obtain a precursor material, and c) heating the precursor material to obtain the porous carbon material having a modal pore size and a pore volume. In order to avoid a lengthy hydrothermal treatment and to allow tunability of the pore size, pore size distribution and pore volume in carbon material, it is proposed that the heating step c) comprises a low temperature treatment in which the precursor material is heated to a first temperature in the range between 300 DEG C and 600 DEG C to obtain a self-assembled porous carbonaceous material, and wherein heating to the first temperature comprises a first average heating rate in the range of 0.5 DEG C/min to 5 DEG C/min.
制备具有分级孔隙率的多孔碳材料的已知方法包含步骤：a)提供至少一种碳源和至少一种两亲物类，b)合并碳源和两亲物类以获得前体材料，和c)加热所述前体材料以获得具有模态孔径和孔隙体积的多孔碳材料。为了避免漫长的水热处理并实现碳材料中的孔径、孔径分布和孔隙体积的可调谐性，提议加热步骤c)包含低温处理，其中将前体材料加热到在300℃至600℃之间的第一温度以获得自组装多孔碳质材料，并且其中加热到第一温度包含在0.5℃/min至5℃/min的范围内的第一平均加热速率。
