Low-temperature preparation and properties of rhodamine B-sensitized anatase TiO_2

The rhodamine B dye-sensitized anatase TiO2 powders were prepared at low temperature(60 to 80℃) in this work.The properties of the photocatalysis were characterized by XRD,FT-IR,PL and UV-vis absorption spectra.The results indicate that there is a strong mutual action between rhodamine B and TiO2,and there is a stronger absorption in visible light range for the sample.The photocatalytic degradation results reveal that there is a high activity for photocatalytic degradation under the fluorecent light.
