| 1. A method of making a porous carbon comprising
(a) curing a mixture under conditions effective so as to produce a cured carbon, said mixture comprising:
(i) at least one carbohydrate,
(ii) at least one dehydrating component, and
(iii) at least one pore-forming agent comprising a nonmetallic cation of a nonmetal salt; and
(b) carbonizing the cured carbon under conditions effective to provide a porous carbon having a surface area between about
100 m2/g and about 3000 m2/g, wherein said at least one pore forming agent comprises an ammonium cation, wherein step (a)
includes removing substantially all of the water from the mixture and wherein step (a) includes producing a porous monolith.
