The Preparation and Visible Light Photocatalytic Activity of TiO2/Co2+ Nanofibers

Article Preview

Abstract:

TiO2/Co2+ composite nanofibers were prepared by using the electrospun fibers of PVP/ Ti (OiPr)4/Co (NO3)2 composite as precursor, and through calcination treatment. The chemical components, structures and morphology were characterized by TGA, 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 TiO2/Co2+ composite nanofibers calcined at 600 °C which was the anatase 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.
