Description: TOPIC: CARBON CAPTURE WITH LEWIS BASE DERIVATIZED METAL-ORGANIC FRAMEWORKS
Abstract: The United Nations Intergovernmental Panel on Climate Change recently released its Fifth Assessment Report. The report states that human activity is extremely likely (95-100%) to have been the dominant cause of the observed warming since the mid-20th century. The results of this climate change will have impacts that include alteration of ecosystems, disruption of food production and water supply, damage to infrastructure and settlements, human morbidity and mortality and consequences for mental health and human well-being.One promising method to mitigate the impacts of greenhouse gas emission is Carbon Capture and Sequestration (CCS). An effective material for carbon capture must selectively bind carbon dioxide and not bind other gases that are present in the atmosphere and in waste streams. It must be easy to regenerate, requiring a small energy input to release the pure carbon dioxide so that it can be isolated from the environment. Research in our laboratory is focused on the development of Metal-Organic Frameworks, or MOFs, for this purpose. MOFs are crystalline, porous solids containing metal ions and organic linkers. The construction of these materials is similar to Tinker Toys on an atomic level, where metal ions function as spools and organic linkers function as rods. Our strategy involves the inclusion of electron donating sites within the pores of MOFs that will interact more strongly with carbon dioxide than with other molecules in air (e.g. oxygen and nitrogen). The seminar will explore the synthesis and structure of porous MOFs and Covalent Metal-Organic Networks (CMONs) with open electron donating sites. The gas sorption properties of the synthesized materials will be discussed, as well as strategies to improve their selectivity for carbon dioxide capture.
Biosketch:
Dr. Manke received his Bachelor's at Brandeis under Wenbin Lin (now at U of Chicago) who is one of the world's experts in MOFs, his Ph.D. under the MIT Professor of Energy, Daniel G. Nocera (now at Harvard) and performed Post-doctoral work at Cornell under Peter T. Wolczanski, working on carbon dioxide reduction. He has extensive experience in synthetic inorganic chemistry, particularly as it related to clean energy problems. Previous funding while at UMass Dartmouth includes two National Science Foundation grants and a grant from the Camille and Henry Dreyfus Foundation.
