From Multimetallic Catalysts to Nanoscale Phosphides: Atomically Precise Synthesis for Sustainable Solutions


This talk will focus on our efforts to develop new chemistries that will help reduce non-renewable energy use through improved energy efficiency and mitigating carbon dioxide emissions via photochemical and catalytic transformations. Our approach focuses on fully solution-processable (i.e., inexpensive) chemical systems capable of sunlight absorption, color-pure emission, charge transfer, and fuels generation with high efficiency and minimal environmental impact. This approach requires addressing fundamental challenges in the field of nanoscience, specifically controlling the composition and the interfaces of nanomaterials to gain reliable control over their electronic structure. Towards this end, we are interested in making contributions in two key areas: 1) understanding the mechanisms of nucleation and growth of semiconductor nanocrystals and 2) understanding how to productively direct energy transduction in semiconductor nanocrystals for application in energy efficient solid state lighting, electricity generation, and fuel formation. I will address each of these areas briefly, but focus primarily on the progress we have made towards understanding the precursor conversion reactions, nucleation and growth mechanisms, and approaches to the post-synthetic transformation of indium phosphide quantum dots.
