MOF-177 is a porous crystalline material that consists of Zn40 tetrahedrons connected with benzene tribenzoate （BTB） ligands, It is an ideal adsorbent with an ex- ceptionally high specific surface area （BET〉4500 m^2/g）, a uniform micropore size dJstrJbutJon with a median pore diameter of 12.7 A, a large pore volume （2.65 cm^3/g）, and very promising adsorption properties for hy- drogen storage and other gas separation and purification applications. A hydrogen adsorption amount of 19.6 wt.% on MOF-177 at 77 K and 100 bar was observed, and a CO2 uptake of 35 mmol/g on MOF-177 was measured at 45 bar and an ambient temperature.
