ABSTRACT
TiO2 electrodes loaded with Au-Ag alloy nanoparticles, Ag content of which is about 0.25-0.90, exhibit stable anodic photocurrents due to plasmon-induced charge separation (PICS) in the presence of an electron donor. The PICS wavelength is blueshifted and the PICS efficiency is enhanced by increasing the Ag content in the nanoparticles.
