Claim:
1. A method of making porositized/activated carbon comprising the steps of: loading a porositizing agent, or a mixture of porositizing agents, to carbon materials selected from the group consisting of charcoal, coal, peat, lignite and petroleum coke, or a carbonaceous material, to generate a carbon material/metallic compound aqueous dispersion, or a carbonaceous material/metallic compound aqueous dispersion, wherein the porositizing agent or mixture of porositizing agents comprises metallic compounds formed from the aqueous dispersion, wherein the metallic compounds include metals selected from the group consisting of Fe, Cu, Zn, Ag, Cr, Co, Pt, Pd, Rh, Re, Mn, Sn, V, Pb, Ge, As, Se, Mg, Ca, Ba, Mo, Ru, Os, Ir, Y, and combinations thereof, and wherein the metallic compounds are formed in situ in the aqueous dispersion by adding a base solution to the aqueous dispersion and mixing the resulting mixture; subjecting the carbon material/metallic compound aqueous dispersion, or the carbonaceous material/metallic compound aqueous dispersion, to a thermal treatment at a desired temperature above about 300° C. to give a thermally-treated carbon material/metallic compound mixture, or a thermally-treated carbonaceous material/metallic compound mixture; and subjecting the thermally-treated carbon material/metallic compound mixture, or the thermally-treated carbonaceous material/metallic compound mixture, to an acid to yield porositized/activated carbon.
