A microporous aluminum-based metal-organic framework for high methane, hydrogen, and carbon dioxide storage

We report a microporous aluminum-based metal-organic framework (MOF), BUT-22 for high methane (CH4), hydrogen (H-2), and carbon dioxide (CO2) storage. At 296 K and 80 bar, BUT-22 exhibits a high gravimetric CH(4)storage capacity of 530 cm(3)(STP)/g (0.379 g/g). BUT-22 also has a high gravimetric H(2)storage capacity of 12 wt.% at 100 bar and 77 K. In addition, the CO(2)adsorption studies revealed that BUT-22 exhibits a high absolute gravimetric CO(2)uptake of 1.7 g/g at 296 K and 40 bar.

Automated summary

BUT-22 is a microporous aluminum-based MOF with high storage capacities for methane, hydrogen, and carbon dioxide, showing excellent performance under different conditions.
