Plasmonic nanomaterials have been extensively investigated because of their fascinating optical properties and broad applications ranging from sensing to energy to medicine. This symposium focuses on the utilization of plasmonic nanomaterials for energy conversion. Plasmonic nanomaterials can drastically concentrate the electric field under resonant excitation which leads to enhanced efficiency of photovoltaics. This field enhancement effect is used to improve the photocatalytic activity for a variety of important reactions such as photocatalytic water splitting. The decay of the plasmon excitation also results in the excitation of high energy carriers, which can subsequently inject into reactant molecules or semiconductors to initiate chemical reactions. Carefully controlling the electron injection processes can potentially open up new possibilities of highly selective catalysis which are otherwise impossible using traditional catalysts. Furthermore, plasmonic materials can efficiently convert light energy to generate heat. The heat generation has been demonstrated for solar vapor generation, for driving a variety of chemical reactions as well as for novel biomedical applications. Finally, the recent discovery of plasmoelectric potentials in metal nanostructures may enable the use of plasmonic materials to directly convert light to electrical energy.
