Carbide-derived carbons are provided that have high dynamic loading capacity for high vapor pressure gasses such as H.sub.2S, SO.sub.2, or NH.sub.3. 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 H.sub.2 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.sup.−1 to 10 mmol g.sup.−1 at a relative humidity of 0% RH to 75% RH.

A biochar-derived adsorbent preferably from Sargassum boveanum, macroalgae can be used for removing phenolic compounds, such as 2,4,6-trichlorophenol and 2,4-dimethylphenol, from aqueous solutions. The carbonization can improve the removal capability of the macroalgae adsorbent for such phenolic compounds with removal efficiencies of 60% or more from high salinity seawater and 100% from distilled water. The adsorption may occur through a mixed mechanism dominated by physisorption following pseudo second-order kinetics. The adsorption of the phenolic molecules may be spontaneous, endothermic and thermodynamically favorable.

Metal-inorganic frameworks (“MIFs”) having enhanced adsorption capabilities to hydrogen, CO, CO.sub.2, hydrocarbons, and a variety of other guest molecules are disclosed. All linkers in the MIFs contain metal complexes, comprising metal atoms and inorganic or organic ligands, instead of only organic ligands as linkers in metal-organic frameworks (MOFs). Compared to their MOF counterparts, MIFs with carbon-free or carbon-deficient chemical structure are expected to possess enhanced thermal stability, higher catalytic activity, and higher gas affinity and selectivity.
