摘要：

Molecular crystals of dipeptides containing open channels can selectively absorb CO2 over N-2 and CH4, as shown by experimental and simulated isotherms. The efficient CO2 capture enabled separation from methane and allowed the direct observation by 2D MAS NMR of CO2 sequestered in the peptide-based biozeolites.
