- 요약The demands of the petrochemical industry put a large stress on the environment, motivating a search for more sustainable methods of chemical manufacturing. One promising technology is plasmonic photocatalysis. Plasmons, the collective oscillation of conduction electron in response to light, give rise to geometry dependent optical properties in nanostructured metallic particles. These resonant optical interactions lead to high energy charge carriers which may participate in chemical reactions. Unfortunately, the ultrasmall and ultrafast interaction of these carriers with molecules is difficult to probe. The focus of this work is to combine automated ensemble level approaches with fundamental investigations in search of the underlying mechanisms of plasmonic photocatalysis. An introduction to the challenges of characterizing plasmonic chemistry is provided in addition to background information on in situ electron microscopy and our model system, Pd hydride. Chapter 2 demonstrates the considerations needed for building a photocatalysis system from scratch. The proceeding two chapters describe the synthesis and testing of two plasmonic alloyed catalysts and their behavior for light-driven acetylene hydrogenation. Finally, similar alloy catalysts are explored using environmental transmission electron microscopy to understand their structure under working conditions, and the final chapter documents efforts to push the frontier of this measurement technique through both rigorous optically coupled ETEM measurements and system improvements. The goal of this project is to explore plasmonic photocatalysis using a multimodal approach in which practical demonstration and fundamental investigation can be performed on the same system.
