PROCESS FOR PREPARING A POROUS CARBON MATERIAL AND A POROUS CARBON MATERIAL OBTAINABLE BY THIS PROCESS
Known processes for preparing a macroporous 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 macroporous 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°C and 600°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°C/min to 5°C/min.
