| Summary: | The structural, optical, and photocatalytic properties of TiO2 and Ag–TiO2 thin films grown by a hydrothermal method were studied by using an x-ray diffractometer, scanning electron microscope, energy-dispersive x ray, and UV–vis spectroscopy. The results indicated that all films were of single-phase and the Ag presence enhanced catalytic and water-splitting performances in the visible light region. In particular, the methylene blue solution was disintegrated up to 99% after 12 and 8 h for TiO2 and Ag–TiO2 films, respectively. Meanwhile, the splitting efficiency increased from 0.3% for TiO2 to 1% for Ag–TiO2. These performances demonstrate the great potential of Ag–TiO2 films in photocatalytic and water-splitting applications.
