In order to investigate the catalytic properties of supported platinum clusters, their interaction with water was monitored using photoelectron spectroscopy. The clusters were exposed to up to five Langmuir of water at cryogenic temperatures. Additio

To achieve an overall efficient solar water splitting device, not only the efficiencies of photo-converter and catalyst are decisive, but also their appropriate coupling must be considered. In this report we explore the origin of a voltage loss occur

In this chapter we discuss at first bulk and interface related requirements of efficient photoelectrochemical device structures for water splitting. Maximized conversion efficiencies need photovoltages produced in the photovoltaic component of the de

GaP, with its large band gap of 2.26 eV (indirect) and 2.78 eV (direct), is a very promising candidate for direct photoelectrochemical water splitting. Herein, p-GaP(100) is investigated as a photocathode for hydrogen generation. The samples are char
