Semiconductor nanocrystals have great potential to serve as photocatalysts for the interconversion of light and chemical energy. Heterostructures, nanocrystals composed of multiple semiconductor components or building blocks, are particularly promising because they facilitate charge carrier separation, resulting in longer excited state lifetimes and spatial separation of the elementary steps of a photocatalytic reaction cycle. One of the biggest challenges for these materials is producing them in a scalable and broadly generalizable manner. Moreover, the assembly of individual nanostructures and reaction co-catalysts into functioning, bio-inspired photosystems remains open for synthetic innovation that will advance catalytic function. This presentation will report on our progress to develop the synthesis science that governs the bottom-up fabrication and assembly of colloidal nanoscale chromophores and their elaboration into functioning photosystems.
