We report a microporous aluminum-based metal-organic framework (MOF),BUT-22 for high methane (CH4),hydrogen (H2),and carbon dioxide (CO2) storage.At 296 K and 80 bar,BUT-22 exhibits a high gravimetric CH4 storage capacity of 530 cm3 (STP)/g(0.379 g/g).BUT-22 also has a high gravimetric H2 storage capacity of 12 wt.％ at 100 bar and 77 K.In addition,the CO2 adsorption studies revealed that BUT-22 exhibits a high absolute gravimetric CO2 uptake of 1.7 g/g at 296 K and 40 bar.
