Cu-Modified LaSiO/TiO composite materials: preparation, characterization and photothermal properties.

Cu-Modified LaSiO/TiO composite materials were prepared by the molten salt method and a solid-phase reduction strategy. Due to the surface plasmon resonance (SPR) of copper, the optical response from the UV to the visible region and near-infrared is increased. In the meantime, it enhances the absorption of visible light by the titanium dioxide and acts as a plasma catalyst.
