AI Technical Summary
Existing metal-organic framework materials are not moisture-resistant and cannot efficiently separate carbon dioxide and nitrogen under humid conditions.
Metal-organic framework materials were prepared by dissolving metal cations, N,N'-(1,4-phenylene)diisonicotinamide and organic ligands in an organic solvent in a specific molar ratio and then reacting them with a solvothermal reaction. The materials contain amide groups and R groups, and the pore size is closely matched with the diameter of CO2 molecules. They have an ultraporous structure and excellent thermal stability and moisture resistance.
It achieves efficient separation of carbon dioxide and nitrogen under dry or high humidity conditions, with mild material regeneration conditions, easy desorption and regeneration, and low energy consumption in the regeneration process.
