16 Claims

1. A process for preparing a porous carbon material comprising the steps:

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,

wherein 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 500° 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, and wherein the low temperature treatment comprises a temperature dwell time of 15 to 240 minutes at a holding temperature lower than the first temperature.
