Abstract


Plasmonic photocatalysts driven by the localized surface plasmon resonance excitation of gold nanoparticle (AuNP) can be an efficient solar-to-chemical converter due to the wide spectral response. This lecture highlights recent studies on the design of the plasmonic photocatalysts for the artificial photosynthesis including water splitting and hydrogen peroxide synthesis from water and oxygen. Firstly, I point to the importance of the establishment of the solar hydrogen and oxygen cycles involving hydrogen and hydrogen peroxide as the key compounds, respectively, for realizing the "sustainable society". Secondly, the basic action mechanisms of the plasmonic photocatalysts consisting of Au NP and semiconductor are explained. Finally, recent advances in the plasmonic overall water splitting and H2O2 synthesis are described.

Keywords
