Abstract
Metal-inorganic frameworks (“MIFs”) having enhanced adsorption capabilities to hydrogen, CO, CO2, hydrocarbons, and a variety of other guest molecules are disclosed. All linkers in the MIFs contain metal complexes, comprising metal atoms and inorganic or organic ligands, instead of only organic ligands as linkers in metal-organic frameworks (MOFs). Compared to their MOF counterparts, MIFs with carbon-free or carbon-deficient chemical structure are expected to possess enhanced thermal stability, higher catalytic activity, and higher gas affinity and selectivity.
Claims20
A metal-inorganic framework (MIF) coordination polymer comprising:
- a plurality of metal clusters, each metal cluster comprising one or more metal ions;
- and
- a plurality of linking complexes connecting adjacent metal clusters.
A method of storing a gas within a metal-inorganic framework (MIF) comprising:
- contacting a MIF having an average pore size of 10 Å with a gas;
- wherein the gas is at a pressure ranging from 14.5 to 725 psi.
