The present invention concerns a process for the preparation of a porous carbon structure comprising the steps: a) providing a template comprising voids, b) filling of at least part of the voids with a precursor for the formation of the porous carbon structure, c) carbonizing the precursor for the formation of the porous carbon structure and d) removing at least part of the template. In preferred embodiments the precursor for the formation of the porous carbon structure is a formaldehyde-phenol resin, especially a cross-linked resorcinol-formaldehyde resin. The template further preferably comprises a block copolymer and an amphiphilic molecule, wherein the block copolymer comprises polymeric units of at least one lipophilic monomer and polymeric units of at least one hydrophilic monomer. Further preferred is a process wherein the template comprises a bimodal mixture of particles of silicon dioxide.
