Their contribution arises essentially from the double layer capacity formed on their surface, which corresponds to 0.14 F m−2 in aqueous electrolytes such as H2SO4 and KOH and 0.06 F m−2 for the aprotic medium (C2H5)4NBF4 in CH3CN. In the case of a series of 27 TMCs, it appears that the effective surface area determined by independent techniques can be as high as 1500–1600 m2 g−1, and therefore exceeds the value obtained for many activated carbons (typically 900–1300 m2 g−1). On the other hand, the relatively low amount of surface oxygen in the present TMCs, as opposed to activated carbons, reduces the contribution of pseudo-capacitance effects and limits the gravimetric capacitance to 200–220 F g−1 for aqueous electrolytes. In the case of non-aqueous electrolyte, it rarely exceeds 100 F g−1.It is also shown that the average mesopore diameter of these TMCs does not improve significantly the ionic mobility compared with typical activated carbons of pore-widths above 1.0–1.3 nm.This study suggests that activated carbons remain the more promising candidates for supercapacitors with high performances.The financial support provided by the Spanish MCyT (MAT2005-00262) is gratefully acknowledged.
