Surface Functionalization of Electrospun TiO_2 Nanofibers by Au Sputter Coating for Photocatalytic Applications

摘要

Au-doped titania (TiO_2:Au) nanofibers were prepared by a combination of the electrospinning method and sputtering technology. The results show that the morphologies of Au-deposited TiO_2 nanofibers can be well controlled by the sputtering time. The photocatalytic decomposition of acetaldehyde on the TiO_2:Au nanofibers was investigated at room temperature. Compared with pure TiO_2 nanofibers, the TiO_2:Au nanofibers exhibited higher photocatalytic activities.
