Abstract
Provided herein are metal organic frameworks having high selectivity and stability in the present of gases and vapors including H2S, H2O, and CO2. Metal organic frameworks can comprise metal nodes and N-donor organic ligands. Further provided are methods of making metal organic frameworks.
Claims20
A metal organic framework, comprising:
- a pillar characterized by the formula (MbF5(O/H2O)), where Mb is an element from periodic groups IIIA, IIIB, IVB, VB, VIB, and VIII;
- and
- a square grid characterized by the formula (Ma(ligand)x), where Ma is Ni2+, ligand is pyrazine, and x is 2;
- wherein pillaring of the square grids with the pillars forms a metal-organic framework.
1 more element
A method of fabricating a metal organic framework, the method comprising:
- combining a fluorhydric acid solution, a Ni2+ source, a second metal source, and a solvent, sufficient to form a mixture;
- reacting the mixture over a period of time sufficient to form a reacted mixture;
- processing the reacted mixture to provide a metal organic framework via pillaring of square grids with a pillar,
- wherein the pillar is characterized by the formula (MbF5(O/H2O)), where Mb is an element from periodic groups IIIA, IIIB, IVB, VB, VIB, and VIII, and the square grids are characterized by the formula (Ma(ligand)x), where Ma is Ni2+;
- ligand is pyrazine, and x is 2.
