Towards Sustainable Energy and Materials: Creating a New Circular Carbon Economy via Carbon Capture, Utilization and Storage
Abstract: In order to meet the ever-increasing global energy demands while stabilizing the atmospheric CO2 level, the development of carbon capture, utilization and storage (CCUS) technologies is one of the critical needs. In particular, there has been significant efforts to develop CO2 capture solvents and some (e.g., amine-based aqueous solvents) have shown very promising results. Unfortunately, the energy requirement for the current aqueous solvent systems is still considered to be too high. Thus, efforts have been focused on the development of the next generation CO2 capture materials, which are often water-free. Nanoparticle Organic Hybrid Materials (NOHMs) are a new class of organic-inorganic hybrids that consist of a hard nanoparticle core functionalized with a molecular organic corona that possesses a high
degree of chemical and physical tunability. It has recently been discovered that NOHMs have interesting electrolyte properties which may allow the CO2 capture to be pulled by the in-situ CO2 conversion reactions. The development of these unique nanoscale hybrid materials will not only advance CO2 capture materials design but also introduce unique research opportunities in various energy and environmental fields. This seminar will discuss the challenges and opportunities of different CO2 capture and conversion pathways including Negative Emission Technologies (e.g., Direct Air Capture) that can allow the development of circular carbon and hydrogen economy using renewable energy.
