ChE-605 - Highlights in Energy Research seminar series
Colloidal synthesis is a surfactant-assisted approach that has proven to be one of the most powerful solution-based method to tailor the size, the shape and the composition of nanocrystalline materials. This superior control afforded by colloidal chemistry, combined with the solution processability and the rich surface chemistry, provides access to atomically defined nanocrystals with an unprecedented tunability. The Laboratory of Nanochemistry for Energy at EPFL Valais develops synthetic route to colloidal nanocrystals and uses them as platforms to explore new concepts and to advance the knowledge in photo- and electro-catalysis. Our current focus is the conversion of water and CO2 into useful chemical products. In this seminar, after a general introduction on colloidal chemistry, I will discuss our recent work on metal nanocrystals as electrocatalysts for CO2 reduction and on quantum dots nanocomposites as light harvesting antennas.1-3
