Research in the Hupp Laboratory is highly interdisciplinary, within the ranges of Physical, Inorganic, Materials and Organic Chemistry. Most research projects revolve around a theme of studying materials for alternative energy applications and other environmental issues, such as monitoring and destruction of chemical pollutants in water. Two seminars will be given, one on each of the two major research tracks: Metal-Organic Frameworks and Photovoltaic and Photoelectrochemical Energy Conversion.

Seminar 1: Metal Organic Frameworks
​Time and place: December 3, 14:15-15:00h, Seminar room (71121) house 7 floor 1.

This presentation will focus on high-area, permanently microporous, metal-organic framework (MOF) compounds as functional materials. The presentation will touch upon very recent advances in MOF synthesis. These advances are facilitating the construction of exceptionally robust MOFs that show promise for energy-related applications, including: a) hydrogen storage and release, b) chemical separations based on emergent phenomena, c) carbon capture, d) multi-stage catalysis of chemical reactions, and e) light-harvesting and long-range directional energy transfer, followed by catalytic photochemistry. New developments in one or more of these areas will be described.

I will also describe our initial work on hybrid MOFs obtained via “AIM” (Atomic-layer-deposition In Metal-organic frameworks). This materials synthesis strategy has enabled us to build arrays of otherwise synthetically inaccessible, metal-oxide clusters within mesoporous MOFs. Of particular interest are the catalytic and electrocatalytic properties of the first members of this new collection of hybrid materials.


 

Seminar 2: Photovoltaic and Photoelectrochemical Conversion
Time and place
: December 4, 14:15-15:00h, Fakultetsrummet (room 1203) house 1 floor 2.

To convert sunlight to electricity dye-sensitized solar cells (DSCs) employ a strategy that is much like the first stages of photosynthesis, entailing light harvesting by strongly absorbing molecules, followed by fast electron transfer to a charge-transporting conduit. The best existing DSCs convert solar energy to electrical energy with about 14% efficiency – less than half of what is theoretically achievable with cells of this kind. This lecture will focus on: a) understanding what limits the efficiency, and b) illustrating how nanostructured molecular-dye architectures and semiconductor-electrode architectures are might circumvent these limits. Shown will be some illustrative examples that take advantage of newly developed atomic-layer-deposition chemistry, as well as new ways of building effective redox shuttles and light harvesting molecules.

Join after-seminar discussions both days from 15:00-16:00h! Fika will be provided.

Most welcome,

Hanna Ellis, Mohammad Mirmohades and Sonja Pullen.
