Photocatalytic Degradation of Butanol in Aqueous Solutions by TiO2 Nanofibers

摘要

Removal of butanol from aqueous solutions was studied using both custom made and commercial TiO2 photocatalysts. The custom made photocatalytic materials were nanofibers of titanium dioxide doped with nitrogen and subsequently decorated with nanoparticles of platinum or palladium. Pd-decorated photocatalysts were found to be highly efficient in the degradation of butanol under UV-A irradiation compared to Pt-decorated nanofibers or to commercial Degussa P25.
