ChE-605 - Highlights in Energy Research seminar series
Metal–organic frameworks (MOFs) are an emerging class of solid-state materials built up from metal-based nodes and organic linkers. They exhibit permanent porosity and unprecedented surface areas which can be readily tuned through coordination chemistry at the inorganic node and/or organic chemistry at the linkers. The high porosities, tunability, and stability are highly attractive in the context of catalysis. As exemplified by many catalytic enzyme assemblies in nature, site-isolation is a powerful strategy for performing catalytic reactions. MOFs provide an exciting platform for deploying catalysts in a site-isolated fashion and the cavities surrounding them can be engineered to conceptually mimic enzymes. This talk will address new advances in the synthesis and catalytic activity of MOF/Enzyme composite materials developed at Northwestern University.

Approaches to porous materials development to address separation challenges

ChE-605 - Highlights in Energy Research seminar series
Access to clean water along with sustainable energy and the protection of the environment are probably the greatest challenges of our society but also a unique opportunity to reshape our technology landscape. Major molecular separation issues underpin these areas. Take for instance CO2 capture: here, one wishes to separate CO2 from other flue gas (or ambient air) components. Notably, existing separation processes account for 10 to 15% of the world energy consumption. Researchers must propose transformative approaches to molecular separations possibly exploiting the increasing complexity and sophistication of materials available to perform such separations.
This seminar will provide an overview of our research – past and current – in that direction. I will discuss selected examples of our work on the design, synthesis, characterisation and testing of porous materials (i.e. sorbents) to address separation challenges related to environmental, water and energy sustainability. I will focus specifically on our study of metal-organic frameworks and porous boron nitride for applications in carbon management and solar energy conversion. I will describe how our approach to material design, which combines aspects of chemistry, materials science and chemical engineering, enables us to identify key materials structure-property relationships while also accelerating the identification of the ‘best’ material for a given application.
