Functional Materials for Separations
CO2 Capture. We develop composites and capsules of ionic liquids (IL) for CO2 filtration from air in confined spaces and carbon capture directly from the atmosphere. The challenges we are addressing in this field are the low gravimetric CO2 capacity of existing separation materials, inadequate surface area for gas-liquid contact and leaching of liquid from its support upon variable pressures, and the high energy requirement for material regeneration.
For IL capsules, we partner with Prof. Emily Pentzer at the Department of Materials Science and Engineering at Texas A&M University.
Our research in this are have received funding from NASA and DOE.
