An indium-based microporous metal–organic framework, UTSA-22, with unique three-way rod-shaped secondary building units, exhibits efficient methane and hydrogen storage at room temperature. A novel microporous indium-based MOF material with unique 3-way rod-shaped secondary building units (SBUs), UTSA-22, was reported and exhibited high methane (CH 4 ) and hydrogen (H 2 ) storage. At 298 K and 65 bar, the total CH 4 volumetric uptake of UTSA-22 is 174 cm 3 (STP) cm −3 . Moreover, UTSA-22 shows a high CH 4 working capacity of 146 cm 3 (STP) cm −3 in a pressure range of 5–65 bar at 298 K. In addition, UTSA-22 shows a high H 2 gravimetric storage capacity (1.2 wt%) at 298 K and 100 bar.
