Microporous carbon (MPC) and hierarchically porous carbon (HPC) were precisely designed by a colloidal process using the same carbon source and pore template. Tetraethyl orthosilicate (TEOS) hydrolysis and condensation reaction under acid condition yields the MPC featuring a highly microporous structure with BET surface area of 2068 m2g−1and pore volume of 0.99 cm3g−1while the reaction under alkaline condition makes the resulting carbon with hierarchically porous structure (HPC), giving a surface area of 1051 m2g−1and pore volume of 0.8 cm3g−1. MPC is also proved to be a promising candidate for supercapacitors with a high capacitance of 287 F g−1at 0.5 A g−1and 152 F g−1at 50 A g−1.
