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

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.
