Key Points

This research aims to explore the effectiveness of Cu(I)-cluster-based COFs in separating C2H2 from CO2 more efficiently.
Developed two Cu(I)-cluster-based COFs with distinct open metal sites and microporosity.
Evaluated their separation performance for C2H2 and CO2.
Utilized various analytical techniques for characterizing the COFs and assessing separation efficiency.
The Cu(I)-cluster-based COFs showed significantly improved separation rates for C2H2 compared to traditional methods.
Achieved a separation factor of over X for C2H2/CO2 under specific conditions.
Demonstrated tunable microporosity enhanced the selective adsorption of C2H2.

Implication

Investigates C2H2 and CO2 separation using Cu(I)-clusters in COFs, suggesting enhanced efficiency.

Abstract

Incorporating open metal sites into covalent organic frameworks (COFs) offers a promising strategy to enhance acetylene (C2H2) and carbon dioxide (CO2) separation performance. Herein, we report two Cu(I)-cluster-based COFs, Cu-HAPB...
