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.


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.
