Abstract

We introduce a facile crystalline phase control of electrospun TiO₂ nanofibers as well as their enhanced photochemical responses via the combination of electrospinning and pulse laser irradiation in liquid (PLIL). We have successfully performed the transformation of the anatase phase into the rutile phase for electrospun TiO₂ nanofibers driven by a PLIL process. Additionally, the mixed phase of TiO₂ nanofibers showed an enhanced photocatalytic activity for decomposing methylene blue, compared with pure anatase and rutile TiO₂ nanofibers.
