CPP 32: Focus Session: Novel Approaches to Surface Plasmon Generated Charges and Heat for Photocatalysis I (joint session O/CPP)

Wednesday, March 20, 2024, 15:00–17:30, MA 141

Plasmonic nanostructures present efficent optical antennas to generate energetic charges and/or localized heat for the use in photocatalysis. The time and length scales of typical plasmon-induced processes however pose a formidable challenge, which today still hinders the large-scale implementation of plasmon photocatalysis. The aim of this focus session is to discuss the physical mechanism of plasmon-induced charge-transfer and heat generation processes and exchange ideas on novel materials and devices utilizing these processes.
