## Abstract Ordered mesoporous carbideβderived carbon (OMβCDC) materials produced by nanocasting of ordered mesoporous silica templates are characterized by a bimodal pore size distribution with a high ratio of micropores. The micropores result in outstanding adsorption capacities and the wellβdefi
tics and a fast charge-discharge rate with a time constant of 6 s. The gravimetric specific capacitance and energy density of OMC oxidized at 60 Β°C are 138 F g Γ1 and 3.9 Wh kg Γ1 , respectively, at a scanning rate of 5 mV s Γ1 . These values are, respectively, 57% and 63% greater than for the un-t
