摘要:

Fe-doped TiO2, microspheres with hollow interiors were prepared using polystyrene latex particles as the template and peroxo-titanium complex as the precursor. The resulting samples are characterized by XRD, SEM, TEM, XPS and UV-Vis. The results reveal that the Fe-doped TiO2 hollow microspheres show pure anatase phase and have a good hollow structure. When adding a concentration of Fe into the system, the electronic structures changed and obviously enhance the absorption in the visible light region. TiO2 hollow microspheres with 0.75% Fe dosage exhibited the superior photocatalytic activity for the decomposition of methylene blue under visible-light irradiation. The possible photocatalytic mechanism is proposed.
