Mesoporous Carbon with CNT Skeleton and their Electrochemical Properties

A kind of Carbon nanotube-implanted mesoporous carbon sphere (CNTs-MCS) is successfully prepared by a facile polymerization-induced colloid aggregation method using gelatin as a soft template. SEM, TEM, BET measurement and BJH method reveal that the obtained CNTs-MCS possess a mesoporous character, with specific surface area (284 m(2).g(-1)) and uniform pore size of 3.9 nm. As the electrode material for supercapacitor in 6 mol.L(-1) KOH, a low equivalent series resistance of 0.9 Omega cm(2) and a maximum specific capacitance of 189 F.g(-1) with a measured power density of 8 kW.kg(-1) at energy density of 26.3 Wh.kg(-1) are obtained.
