Hierarchical porous carbons can exhibit excellent adsorption performance due to their high connectivity of narrow pores provided by the textural transport pores that allowing rapidly deep penetration of adsorbate molecules into the pore network [1, 2]. They have been attracting widespread attention due to their potential technological applications, such as in adsorption of harmful materials in liquid or gas phase, in catalyst support, and as carbon electrode for supercapacitors [3, 4, 5, 6, 7, 8, 9, 10, 11]. The hierarchical micro/meso-porous carbons have been prepared by CO2 activation of ordered mesoporous carbon and utilized as the electrode material for supercapacitor . Meanwhile, a hierarchical meso/macro-porous carbon monolith has been obtained by using Pluronic F127 and SiO2 opal as the templates . In addition, a 3D aperiodic hierarchical porous graphitic carbon material has also been reported . All of these porous carbons exhibited notable...
