Abstract: Molecules, Materials, and Processes for Electrifying Carbon Capture
Carbon capture is considered a critical means for climate change mitigation. Unfortunately, conventional thermochemical methods are energy-intensive and fossil fuel-dependent, motivating the search for more efficient carbon dioxide separation strategies driven by non-thermal energy transfer. In this talk, I will share our research efforts on developing materials and processes for electrochemically mediated carbon capture. I will first present a library of redox-tunable organic molecules that can reversibly capture and release carbon dioxide through an electrochemical cycle. Strategies to finetune sorbent properties and break the scaling relationships will be introduced. I will then discuss challenges and opportunities for sorbent and electrochemical reactor designs toward practical carbon capture processes driven by electrochemical stimuli.
Bio:
Yayuan Liu joined the Department of Chemical and Biomolecular Engineering at Johns Hopkins University as an assistant professor in January 2022. Her research group works at the interface of chemical engineering, materials science, and electrochemistry to accelerate the realization of energy and environmental sustainability. She earned her Ph.D. in materials science and engineering in 2019 from Stanford University under the guidance of Dr. Yi Cui and completed her postdoctoral training at the Massachusetts Institute of Technology, working with Dr. T. Alan Hatton in the Department of Chemical Engineering. She has received multiple recognitions for her research, such as the NSF CAREER award, the Beckman Young Investigator award, the Packard Fellowship, and the Electrochemical Society Toyota Young Investigator award.
