摘要：

We report plasmonic nanoparticle enhanced photocatalysis on titanium dioxide (TiO2) in the deep-UV range. Aluminum (Al) nanoparticles fabricated on TiO2 film increases the reaction rate of photocatalysis by factors as high as 14 under UV irradiation in the range of 260-340 nm. The reaction efficiency has been determined by measuring the decolorization rate of methylene blue applied on the TiO2 substrate. The enhancement of photocatalysis shows particle size and excitation wavelength dependence, which can be explained by the surface plasmon resonance of Al nanoparticles. (C) 2014 AIP Publishing LLC.
