Covalent organic framework (COF) membranes used for selective removal of CO2 were believed as an efficient and low-cost solution to energy environmental sustainability. In this study, the amide modified COF nanosheet cluster with a 2D structure was facilely prepared through solid reaction, exhibiting good adsorption-based selectivity (223 at 273 K 90 298 K) toward N2. Remarkably, mixed matrix membrane (MMM) that consists lesser amount filler (1 wt %) shows promising CO2/N2 gas (∼64). addition, competitive adsorption prompts ∼72 under equimolar mixture, which surpasses values all reported membranes. It is worth note binary separation stable during 120 h.
