Development of porous metal–organic frameworks (MOFs) with enhanced stability and high methane working capacity is of paramount importance to facilitate the use of natural gas as a transportation fuel. In this work, we used C₃-symmetrical tricarboxylates to construct two isoreticular Zr-based MOFs (ZJNU-30 and ZJNU-31) featuring the coexistence of a one-dimensional channel and two different types of cages in the overall structures. High-pressure methane adsorption studies show that the two compounds have good methane adsorption capacities. In particular, the methane working capacity of ZJNU-30a is among the highest reported for Zr-based MOFs. More importantly, the two compounds display exceptional hydrostability, making them attractive for use as a methane adsorbent.
