1. A method for removing chloramine from aqueous solutions comprising: providing an aqueous solution comprising chloramine and contacting the aqueous solution with a composition comprising a thermolysis product of (a) a carbon substrate having a surface comprising COxEy wherein E is selected from at
1. A method for removing chloramine from aqueous solutions comprising: providing an aqueous solution comprising chloramine and contacting the aqueous solution with a composition comprising a thermolysis product of (a) a carbon substrate having a surface comprising COxEy wherein E is selected from at least one of S, Se, and Te wherein x and y are greater than 0 and (b) a metal salt, wherein the metal comprises at least one of copper, iron, silver, and manganese. 2. The method of claim 1, wherein the metal salt comprises (i) a metal carboxylate; (ii) nitrogen-containing oxyanion metal salt; (iii) a sulfur-containing anion metal salt; (iv) a metal chloride; (v) a metal phosphate; or (vi) combinations thereof. 3. The method of claim 1, wherein x is no more than 0.1, and y is 0.005 to 0.3. 4. The method of claim 1, wherein x is 0.01 to 0.1. 5. The method of claim 1, wherein the composition comprises less than 0.90, mass % nitrogen based on the total mass of the composition. 6. The method of claim 1, wherein the composition comprises greater than 2.0 mass % sulfur based on the total mass of the composition. 7. The method of claim 1, wherein the composition comprises greater than 4.0 mass % sulfur based on the total mass of the composition. 8. The method of claim 2, wherein the sulfur-containing anions metal salt comprises a sulfate, sulfamate, sulfite, bisulfate, bisulfite, thiosulfate, or combinations thereof. 9. The method of claim 2, wherein the metal carboxylate comprises an oxalate, an acetate, a citrate, or combinations thereof. 10. The method of claim 1, wherein E is sulfur and the sulfur is chemically combined with carbon. 11. The method of claim 1, wherein the composition comprises less than 0.70, mass % nitrogen based on the total mass of the composition. 12. The method of claim 1, wherein the composition comprises less than 0.30, mass % hydrogen based on the total mass of the composition.
