Fe-doped TiO2 (Fe-TiO2) and N, Fe co-doped TiO2 (N-Fe-TiO2)
nanomaterials were synthesized by solid-state reaction, respectively. The textural properties of
the samples were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM),
ultraviolet visible light spectroscope (UV-Vis), X-ray photoelectron spectroscope (XPS). The
components of the samples were determined by atomic absorption spectrum (AAS) and automatic
elemental analyzer. Moreover, the photodegradation properties of quinoline irradiated under
visible light on the materials were investigated. The results show that N atoms as N3- states are
incorporated into the lattice of TiO2, and Fe3+ ions occupy the sites of Ti4+ by isomorphous
replacement in the spheric shape N-Fe-TiO2 nanomaterials. The UV-Vis absorption onset of the N-
Fe-TiO2 samples extends well into the visible region at 600 nm. Furthermore, an increase of the
initial ratio of N2H4 center dot H2O to FeCl3 center dot 6H(2)O enhances the phase transformation
of N-Fe-TiO2 catalysts. At 25 degrees C, pH=6.5, the rule of pseudo-first-order reaction and
excellent photocatalytic activity on the N-Fe-TiO2 catalysts are found in the process of
photodegradation of quinoline. However, quinoline can not be degradated by pure TiO2 under
visible light irradiation. The reaction rate constant of N-Fe-TiO2 (n(N2H4H2O): n(FeCl(3)6H(2)O)
=1:9) catalyst is higher than that of pure TiO2 powder.
