Methods and Compositions for Removing Carbon Dioxide from a Gaseous Mixture

The structure of 1 showing 1D open channels. Color scheme: Zn: cyan, N: blue, O: red and C: grey. H atoms and DMF are omitted for clarity.


Invention Summary:

Rutgers researchers have developed a method for separating carbon dioxide from a mixture of gases by way of passing said mixture through a porous polymeric coordination compound. The compound is a three-dimensional network with one-dimensional channels made of Zn metal and two polyfunctional ligands with binding sites conducive to CO2 removal.

Market Application:

Sequestration of greenhouse gases as related to combating anthropogenic climate change.

Advantages:

The MMOFs presented are highly promising candidates for use in high selectivity capture of CO2 under low temperature or high pressure conditions. They offer a low-cost and high-efficiency alternative more suitable for CO2 adsorption in industrial process over current CO2 separation methods.
