Synthesis of Large-Pore Ia$bar 3$d Mesoporous Silica and Its Tubelike Carbon Replica

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).
