Azobenzene Decorated NbO-Type Metal-Organic Framework for High-Capacity Storage of Energy Gases
Herein, a microporous NbO-type framwork (FJI-H23) that showed outstanding surface area (3740.4 m(2).g(-1)) was fabricated by utilizing an azobenzene-derived carboxylate ligand. As anticipated, FJI-H23 can store 2.35 wt % H-2 at 77 K up to 1 bar. Furthermore, FJI-H23 exhibits high-capacity storage of C2 and C3 hydrocarbons at room temperature. Especially, the uptake amount of C3H8 is 325.76 cm(3).g(-1) at 298 K, which represents the new record of C3H8 adsorption capacity in the MOFs materials. In addition, FJI-H23 exhibits excellent gravimetric total uptake of 332 cm(3).g(-1) at 298 K and 65 bar.
