Japanese scientists have improved the gas separation efficiencies of porous materials by precisely tuning the framework’s flexibility. Separating gas mixtures is important for generating cleaner gases for industrial energy applications. For example, carbon dioxide needs to be removed from biogas and ethane from natural gas to increase the methane content.
Porous coordination polymers are promising candidates for gas separation and this new study show that specific design of them can contribute to improved industrial separation processes.
