A Stable Porous Framework for Efficient Storage of C2–C3 Hydrocarbons

Abstract

Since hydrocarbons have been widely used in industrial production, it is particularly important to prepare stable and efficient crystalline porous materials for gas storage. Metal‐organic frameworks are an excellent kind of gas storage materials because of their high void volumes, adjustable pore structures, and excellent specific surface areas. Here, a stable framework (FJI‐W‐Ni) with a high Bruner–Emmet–Teller surface area (1511 m2 g−1) is reported, which has high‐density N/O/F atoms in the pore. FJI‐W‐Ni can not only maintain its skeleton in various organic solvents but also remain stable at high temperatures, which can be demonstrated by powder X‐ray diffraction patterns. In addition, single‐component gas adsorption tests show that FJI‐W‐Ni has high adsorption capacity of C2–C3 hydrocarbons at 298 K and 1 atm. For example, the saturated adsorption capacity of acetylene (C2H2) and allylene (C3H4) can reach 124.56 and 175.84 cm3 g−1, respectively.
