ACTIVATED CARBON MATERIALS, AND METHODS OF PREPARING THEREOF AND USES THEREOF
Provided is a method of producing activated carbon from a resin composite made up of furanic polymer. The method includes producing a resin composite from feedstock (e.g., in the presence of an acid and a salt), combining the resin composite with a base to form an impregnated material, and carbonizing the impregnated material to produce the and salt activated carbon. Provided herein are also resin composites and activated carbon materials.

isolating the resin composite; and
drying the resin composite,
wherein the resin composite comprises:
a plurality of particles, wherein each particle independently comprises furanic polymer, and
salt, wherein at least a portion of the salt is incorporated into at least a portion of the particles.
