Characterization of nanostructed gas sorbents by TPD/FTIR measurements
EMSL Project ID
6896
Abstract
This project directly supports DOE's environmental mission areas in the CO2 emission control. Novel sorbent materials are synthesized by grafting amine functional groups to a variety of nanostuctured substrates such as carbon nanotubes and mesoporous silica. We propose to charaterize the adsorption/desorption properties of these materials by temperature-programed desorption and follow the surface chemistry by direct FTIR measurements as well as mass spectrometry of the evolved gas. The information that will be obtained from this work will help us understand the reactions of CO2 and common flue gas contaminants such as SO2 and water with solid amine sorbents. Equipped with such knowledge of surface chemistry, we can tailor the amine ligands for optimal CO2 capture materials.
