An indium-based microporous metal–organic framework with unique three-way rod-shaped secondary building units for efficient methane and hydrogen storage
Abstract
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 (CH4) and hydrogen (H2) storage. At 298 K and 65 bar, the total CH4 volumetric uptake of UTSA-22 is 174 cm3(STP) cm−3. Moreover, UTSA-22 shows a high CH4 working capacity of 146 cm3(STP) cm−3 in a pressure range of 5-65 bar at 298 K. In addition, UTSA-22 shows a high H2 gravimetric storage capacity (1.2 wt%) at 298 K and 100 bar.
