摘要

The efficient separation of acetylene (C₂H₂) and ethylene (C₂H₄) is an important and complex process in the industry. Herein, we report a new family of lcy-topologic coordination frameworks (termed NTU-90 to NTU-92) with Cu₃MF₆ (M = Si, Ti, and Zr) nodes. These charged frameworks are compensated by different counterbalanced ions (MF₆^2-, BF₄^-, and Cl^-), yielding changes in the size of the window apertures. Among these frameworks, NTU-92-a (activated NTU-92) shows good adsorption selectivity of C₂H₂/C₂H₄ and also significant ability in recovering both highly pure C₂H₄ (99.95%) and C₂H₂ (99.98%). Our work not only presents a potential alternative for energy-saving purification of C2 hydrocarbons but also provides a new approach for tuning the function of charged porous materials.
