Preparation of Au/TiO2 exhibiting strong surface plasmon resonance effective for photoinduced hydrogen formation from organic and inorganic compounds under irradiation of visible light

Au/TiO2 samples exhibiting stronger photoabsorption at around 550 nm due to surface plasmon resonance were prepared by using a multi-step photodeposition method and the samples exhibited higher levels of activity for H-2 production from various compounds such as 2-propanol, ethanol and ammonia in aqueous suspensions under visible light irradiation.
