Competitive Advantages
- Enhances CO₂ interactions
- Reduces interactions with water vapor
- Simple, inexpensive chemicals
- Facile to activate and reactivate
Summary
USF inventors have utilized these strategies to develop a unique class of porous MOM platforms that exhibit highly selective adsorption for polarizable gases, like CO2, over other gases, including water vapor, methane, nitrogen and hydrogen. These platforms are based upon saturated metal centers with inorganic anion pillars that offer superior performance to existing porous materials due to the electrostatics of the frameworks, which are particularly favorable to CO2 more than other gases. The selectivity of CO2 over water is an especially rare phenomenon for porous materials, since water is usually the preferred molecule. In addition, these materials are facile to activate and reactivate, and they are based on simple, relatively inexpensive chemicals. These properties demonstrate important implications for any industrial process involving CO2, including carbon capture and natural gas upgrading.
