Electrospinning Fabrication of SrTiO3 Nanofibers and Their Photocatalytic Activity

Abstract

SrTiO₃ nanofibers were fabricated by an electrospinning process. The phase, microstructure and photocatalytic activity of the obtained SrTiO₃ nanofibers were investigated. The XRD patterns and the SEM images suggest that SrTiO₃ nanofibers with perovskite phase and rough surface have been fabricated in the current work. The SrTiO₃ nanofibers show a high efficiency decomposition of RhB under ultraviolet light irradiation. The high photocatalytic activity of SrTiO₃ nanofibers results from the large specific surface area. The large specific surface area provides more surface active sits and makes an easier charge carrier transport. On the basis of the photocatalytic performance of SrTiO₃ nanofibers, the possible photocatalysis mechanism was proposed.
