Designing Plasmonic Photocatalysts — Emiliano Cortes and •Andrei Stefancu — Nanoinstitute Munich, Faculty of Physics, University of Munich (LMU), Munich, Germany

Nanostructured surfaces and colloids with designed optical functionalities - such as plasmonic & photonic nano and metamaterials - allow efficient harvesting of light at the nanoscale. Exploiting light-driven matter excitations in these artificial materials opens up a new dimension in the conversion and management of energy at the nanoscale [1-4]. One example are plasmonic and photonic catalysts, that can indeed confine solar energy into molecular regions [4-11]. In this talk, I will present our recent efforts in order to understand the light-matter interaction in plasmonic nanoparticles and metamaterials for photocatalysis [1-11].
