Despite a growing awareness of the effects of climate change across the globe, carbon dioxide (CO2) emissions persist as a primary cause of global temperature extremes. The progressive increase in worldwide carbon emissions provides a critical need for developing new materials that can capture, sequester, and re-utilize carbon emissions to reduce the impacts of climate change. Metal-organic frameworks (MOFs) possess a promising potential to fulfill this need due to their structural and chemical modularity.1 Most MOFs for selective carbon capture reported to date experience truncated uptake or structural destabilization amidst humid conditions, rendering these materials unusable for industrial conditions. To address the limitations preventing industrial viability, in this talk, I will describe the use of MIL-120 as a cost-effective, ecologically sustainable, and waterstable MOF exhibiting selective CO2 uptake in humid flue gas conditions.2 Its regenerability as a CO2 adsorbent and its conserved stability under high temperatures and water exposure suggests its suitability for use in industry.
Applying this material to post-combustion carbon capture can limit the volume of CO2 released into the atmosphere and meet the reduced emission goals. Toward the end of my talk, I will discuss our approaches to discovering MOFs as efficient catalysts to convert CO2 into value-added products.
Short Bio: Kyriakos obtained his Ph.D. degree in materials chemistry at the University of Liverpool, UK. Upon completing his Ph.D. thesis, he was awarded the prestigious Marie Curie individual fellowship to work at the Catalan Institute of Nanoscience and Nanotechnology, ICN2, in Barcelona, Spain. In 2015, he moved to EPFL Valais in Sion, Switzerland, as a team leader within LSMO and started his independent research career. In 2019, he joined the Department of Chemistry at Oregon State University as an Assistant Professor and leads the Materials Discovery Laboratory (MaD Lab). His team’s interests are based on the design and synthesis of porous MOFs for carbon capture and separation, hydrogen generation, the capture of hazardous molecules such as ammonia and iodine, and sensing applications.
