Photoelectrochemical analysis of size-dependent electronic structures of gold clusters supported on TiO2
Abstract
Size-dependent electronic structures around the Fermi level of glutathione-protected gold clusters (0.9–1.4 nm in core diameter) were analyzed on the basis of photoinduced charge separation at the interface between the gold cluster and TiO2. Electron levels such as HOMO and LUMO were estimated from the dependencies of the photocurrents on the irradiation wavelength and the standard electrode potentials of
