Original Abstract
Water treatment and pollutant degradation is a hot research topic these days and photocatalytic reactions provide promising results for this application domain. The most common catalyst for these applications is titanium dioxide with a bandgap varying around 3,2 eV which corresponds to the UV-A radiation spectral range. As alternative material to TiO2,tungsten trioxide can be used. With bandgap around 2,8 eV visible light can be used for excitation. However, the high rate of recombination of photoexcited electrons from conduction band back to valence band constitutes a major drawback of traditional photocatalysis.
