A Systematic Approach to Building Highly Porous, Noninterpenetrating Metal–Organic Frameworks with a Large Capacity for Adsorbing H2 and CH4

Highly porous metal organic framework materials having closely related structures and systematically tunable porosity demonstrate a high capacity for methane and hydrogen adsorption. At room temperature and ≈40 bars, the compounds Zn(BDC)(TED)0.5 and Ni(NDC)(TED)0.5 adsorb 242 cm3 g−1 and 173 cm3 g−1 of CH4, respectively. At 77 K, they take up 4.1 and 5.5 wt% of hydrogen at 40 and 65 bars, respectively.
