We report on a detailed textural analysis of mechanochemically synthesized MOF‐199 including N 2 adsorption‐desorption and CO 2 adsorption isotherms data at 77 K and 273 K (up to atmospheric pressure), respectively, and CH 4 adsorption data at 298 K (up to 35 bar). We used the isotherm adsorption data to determine the micropore volume of the MOF‐199 structures, to establish their methane uptake capacity and to understand how these properties depended on the Ethanol/BTC ratio used during the synthesis. The maximum methane uptake capacity for our specimens was recorded at 130 v/v at 35 bars. These results open an avenue for a better understanding of alternative manufacturing processes of MOF structures for gas storage applications.
