Project Overview

Post-Synthetic Modification of Materials for Carbon Dioxide Separations

Faculty Sponsor

Matt Hudson (




Due to global greenhouse gas emissions, the atmospheric carbon dioxide level has risen to over 400 ppm, an increase of over 100 ppm from just 60 years ago. Post-combustion carbon capture and sequestration methods have been shown to be useful in stemming this rise in carbon dioxide emissions however the current separation methods/materials are inadequate due to toxicity and cost. Powerplant flue-gas has low partial-pressures of carbon dioxide, compared to that of nitrogen, which makes finding a material that selectively captures carbon dioxide at low partial pressures essential to making a great adsorbent material. We will prepare and post-synthetically modify different porous adsorbents in the form of metal-organic frameworks (MOFs) and zeolites to better capture and separate carbon dioxide. Post-synthetic methods will involve the polymerization of amines and epoxides into MOF/zeolite materials whose stability, structure, and gas adsorption properties will be characterized. Depending on interest, a non-synthetic fully computational project looking at the carbon dioxide adsorption in MOFs via state-of-the-art solid-state modeling software may be considered. No prior experience in solid-state synthesis, computational chemistry, or materials chemistry are needed or expected. Students interested in these research opportunities should reach out and discuss this further with Professor Hudson.
