Claim 7:
8. A system for separating carbon dioxide from a mixture comprising:
a chamber having an inlet adapted to direct the mixture into the chamber; and
a sorbent comprising a metal organic framework (MOF) positioned within the chamber, wherein the MOF comprises:
a plurality of secondary building units (SBUs), each SBU comprising a repeating unit of one metal cation connected to another metal cation via a first moiety of an organic linker;
a layer of connected adjacent SBUs in which a second moiety of the organic linker in a first SBU is connected to a metal cation of an adjacent SBU,
wherein adjacent layers are connected to each other via linker-to-linker bonding interactions;
and wherein each metal ion is selected from cobalt(II) ions, manganese(II) ions and nickel(II) ions, the organic linker is 5-aminoisophthalate, the first moiety is a carboxylate group and the second moiety is an amino group.
