Fe3+-modified SnO2 nanoparticles were directly prepared by hydrothermal method, and were characterized by X-ray diffraction (XRD), transmission electron microscope (TEM), Fourier transform infrared (FT-IR) spectroscopy, and UV-Vis diffuse reflectance spectra (DRS). It was found that rutile phase was directly synthesized without calcination. The Fe3+-modified SnO2 nanoparticles were well dispersed with narrow size distribution. The crystalline size of SnO2 decreased from 6.0 to 3.8 nm when the Fe3+ content increased from 0 to 20%. The specific surface area of pure SnO2 was 206.1 m2•g−1, and it increased to 259.8 m2•g−1 when Fe content was 15%. A considerable red shift in the absorbing band edge was observed as increase of Fe3+ content. XRD and DRS proved that Fe3+ and SnO2 formed solid solution nanoparticles.
