Abstract

An ITO electrode was coated with a nanoporous TiO₂ film, and the film was loaded with Au nanoparticles with different diameters (15, 40 and 100 nm). The electrode exhibited plasmon-induced photocurrents in the presence of Fe^2+/3+ couple under visible light (λ > 420 nm). The quantum efficiency increased with increasing particle size, whereas the maximum photocurrent density decreased.
