Photocatalytic Water Splitting over Ag/TiO₂ Nano-Wire Films

Abstract:

Plasmonic Ag decorated TiO₂ nano-wire film was firstly prepared by the combination of a hydrothermal method and a microwave-assisted chemical reduction process. The results show that Ag deposited TiO₂ film exhibits obvious visible light absorption due to surface plasmon resonance absorption of Ag nanoparticles. Besides, fluorescence quenching is observed in the composite film under the excitation of 250 nm. Photocatalytic tests show that Ag deposited TiO₂ exhibits enhanced photocatalytic activity for H₂ production by water splitting due to the synergistic effect between charge transfer and surface plasmon resonance absorption properties of Ag nanoparticles.
