The Preparation and Visible Light Photocatalytic Activity of ZnO-TiO₂ Nanofibers

Abstract:

ZnO-TiO₂ composite nanofibers were prepared by using the electrospun fibers of PVP/ZnSO₄/ Ti(OiPr)₄ composite as precursor, and through calcination treatment. The chemical components, structures and morphology were characterized by FT-IR, XRD, SEM, respectively. The photocatalytic activities of the catalysts were investigated by photocatalystic degradation of Rhodamine B under visible-light irradiation. It was found that the ZnO-TiO₂ composite nanofibers photocatalyst calcined at 600 °C which was mixed the anatase phase and rutile phase, showed higher photocatalytic activities than those calcined at other two temperatures. This result was expected as a new morphology of photocatalysts to degrade the organic pollutants in the sun.
