Enhanced photocatalysis by coupling of anatase TiO(2) film to triangular Ag nanoparticle island

In order to overcome the low utilization ratio of solar light and high electron-hole pair recombination rate of TiO(2), the triangular Ag nanoparticle island is covered on the surface of the TiO(2) thin film. Enhancement of the photocatalytic activity of the Ag/TiO(2) nanocomposite system is observe...

description In order to overcome the low utilization ratio of solar light and high electron-hole pair recombination rate of TiO(2), the triangular Ag nanoparticle island is covered on the surface of the TiO(2) thin film. Enhancement of the photocatalytic activity of the Ag/TiO(2) nanocomposite system is observed. The increase of electron-hole pair generation is caused by the enhanced near-field amplitudes of localized surface plasmon of the Ag nanoparticles. The efficiently suppressed recombination of electron-hole pair caused by the metal-semiconductor contact can also enhance the photocatalytic activity of the TiO(2) film.
