Abstract
Discloses herein is an activated metal-organic framework of formula as defined in the application, and the metal organic framework has a BET surface area of from 250 to 1,000 m2/g as obtained from a 298 K CO2 sorption isotherm. In a particular embodiment, the activated metal-organic framework is aluminium formate (Al(HCOO)3) or vanadium formate (V(HCOO)3).
Claims22
An activated metal-organic framework of formula I:
- where:
