Carbide-derived Carbons Having Incorporated Metal Chloride Or Metallic Nanoparticles

Abstract

Carbide-derived carbons are provided that have high dynamic loading capacity for high vapor pressure gasses such as H₂S, SO₂, or NH₃. The carbide-derived carbons can have a plurality of metal chloride or metallic nanoparticles entrapped therein. Carbide-derived carbons are provided by extracting a metal from a metal carbide by chlorination of the metal carbide to produce a porous carbon framework having residual metal chloride nanoparticles incorporated therein, and annealing the porous carbon framework with H₂ to remove residual chloride by reducing the metal chloride nanoparticles to produce the metallic nanoparticles entrapped within the porous carbon framework. The metals can include Fe, Co, Mo, or a combination thereof. The carbide-derived carbons are provided with an ammonia dynamic loading capacity of 6.9 mmol g−1 to 10 mmol g−1 at a relative humidity of 0% RH to 75% RH.
