Abstract

Simultaneously involving abundant [NH₂(CH₃)₂]⁺ cations and uncoordinated carboxylate oxygen atoms as dual active sites, two microporous Co^II-MOFs (LCU-105 and LCU-106, LCU = Liaocheng University) both exhibit highly selective adsorption of CO₂/CH₄ and CO₂/N₂. GCMC theoretical simulations provide good verification of the experimental results.
