1. An activated carbon having:
a pore volume A (cc/g) of pores with a size of 1.0 nm or less wherein a pore volume calculated by the Quenched Solid Density Functional Theory (QSDFT) method is 0.300 cc/g or more,
a pore volume B (cc/g) of pores with a size of 1.5 nm or less wherein a pore volume calculated by the QSDFT method is 0.38 cc/g or more,
wherein the activated carbon has a specific surface area, as measured by BET method (single point using nitrogen as an adsorbate) of between 800 and 1,300 m2/g, and
wherein elemental vanadium and/or a vanadium compound is contained in the activated carbon.
