A synthetic route to tubelike mesoporous carbon materials with a cubic structure has been developed by using propylsulfonic acid groups anchored onto a silica wall, which act as an acid catalyst for carbon-source polymerization. Pores with diameters of 2.4 and 4.0 nm were recorded for the carbon replicas obtained after removing the silica walls (see isotherm).
