TiO2 Photocatalyst is widely used in water reduction because it has proper conduction & valance band positions, and excellent photodecomposition resistance. However, TiO2 can only absorb UV range of light, so many researchers have proposed variety methods to absorb long-range of sunlight. One of the powerful ways is combination of Au-TiO2 due to visible-light absorption and large electron reservoir. Here, we suggest hetero Au-TiO2 structures which have (i) visible to near-infrared absorption ranges and (ii) strong localization of plasmon near-fields. In this work, we test hydrogen generation depends on size and shape of gold nanoparticles. |
