Claim:
1. A promoted carbon nanocomposite sorbent made by a method comprising: contacting a carbon precursor and a substrate material, wherein the carbon precursor comprises a carbohydrate, wherein the substrate material comprises diatomaceous earth, clay, zeolite, or a combination thereof, to provide a nanocomposite starting material; heating the nanocomposite starting material, to provide a carbon nanocomposite sorbent; and promoting at least a portion of the carbon nanocomposite sorbent by chemically reacting the portion of the carbon nanocomposite sorbent with a halogen or halide promoter, wherein the halogen or halide promoter is NH wherein the carbon nanocomposite sorbent and the promoted carbon nanocomposite sorbent are multiphase solid materials having at least one phase having at least one dimension that is about 1-1000 nm or having a repeat distance separating at least some of the phases of about 1-1000 nm.
