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

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.

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.

Visible Light Photocatalytic

In this paper, two newly explored TiO2 photocatalyst sensitized with commercial stable pigment (BYH3G and PR254) were prepared and characterized by FT–IR, UV–Vis, XRD and N2 adsorption-desorption isotherms. The adsorption capacities and the photocatalytic activities of as-prepared photocatalysts were evaluated by photocatalytic degradation of Methyl Orange and Rhodamine B under visible light irradiation. The as-prepared photocatalysts displayed high visible light photocatalytic activity than pure TiO2 under the same conditions. The photocatalytic activity can be reproduced commendably demonstrates that the as-prepared photocatalysts are stable and renewable, which are potentially important properties in the application of industrial wastewater treatment.
