Abstract

In the current chapter we discuss the importance of plasmonics for photoelectrochemical water splitting. A survey through plasmonics, the underlying theoretical background, and an overview of selected articles are provided highlighting the different plasmonic-enhanced systems. All relevant diagnostic parameters are explained, and simple band diagrams are chosen to provide a visual overview to explain the main mechanisms taking place. Furthermore, we provide a scope of how the field could progress and what it is still lacking.
