One-step electrospinning route of SrTiO3-modified Rutile TiO2nanofibers and its photocatalytic properties

摘要

The SrTiO~(3) modified rutile TiO~(2) composite nanofibers were synthesized by a simple electrospinning technique. The result of XRD, SEM and TEM indicate that the SrTiO~(3)/TiO~(2) heterojuction has been prepared successfully. Compared with the TiO~(2) and SrTiO~(3), the photocatalytic activity of the SrTiO~(3)/TiO~(2) (rutile) for the degradation of methyl orange exhibits an obvious enhancement under UV illumination. which is almost 2 times than that of bare TiO~(2) (rutile) nanofiber. Further, the high crystallinity and photon-generated carrier separation of the SrTiO~(3)/TiO~(2) heterojuction are considered as the main reason for this enhancement.
