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.

Abstract translation: 提供碳化物衍生的碳，其对于高蒸汽压气体如H 2 S，SO 2或NH 3具有高动态负载能力。 碳化物衍生的碳可以含有多个金属氯化物或金属纳米粒子。 通过将金属碳化物进行氯化从金属碳化物中提取金属以制备其中含有残余金属氯化物纳米颗粒的多孔碳骨架，并用H 2还原多孔碳骨架以通过还原金属来除去残留的氯化物来提供硬质合金衍生的碳 氯化物纳米颗粒，以产生包埋在多孔碳框架内的金属纳米颗粒。 金属可以包括Fe，Co，Mo或它们的组合。 在0％RH至75％RH的相对湿度下，碳化物衍生的碳具有6.9mmol g-1至10mmol g-1的氨动态负载能力。
