一种分级孔单晶HP-MIL-101的合成方法及其分离应用
By preparing hierarchical porous single-crystal HP-MIL-101, combining microporous and mesoporous structures, the limitations of macromolecular diffusion and active site interactions in MOF materials were overcome, enabling tunable mesopore size and efficient ethane/ethylene gas separation, thus improving selectivity and adsorption capacity.

AI Technical Summary
Existing MOF materials are mostly microporous, which restricts the diffusion of macromolecules and the interaction of active sites, making it difficult to meet the application requirements of macromolecule adsorption and separation, large-volume drug delivery and heterogeneous catalysis, and lacking methods for regulating mesoporous structures.
Hierarchical porous single crystal HP-MIL-101 was prepared by uniformly mixing metal salts and organic ligands in water and then reacting via reflux. The mesopore size is adjustable. The network octahedral structure combining micropores and mesopores was combined with the introduction of monovalent copper salts as a carrier to form copper-loaded hierarchical porous single crystal HP-CuⅠ@MIL-101.
A hierarchical pore structure with adjustable mesopore size was achieved, which improved the specific surface area and stability of the material. When used as an adsorbent for ethane/ethylene gas separation, the selectivity and adsorption capacity were significantly improved, with an IAST selectivity of 66, and excellent performance was maintained even after multiple cycles.
