Abstract: SnO2 nanorods were successfully synthesized in molten NaCl-KCl salt through calcination of SnO2 nanoparticles precursor prepared by solid state reaction at room temperature. The structure and morpho1ogy of SnO2 nanorods were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, selected-area electron diffraction, and X-ray photoelectron spectroscopy. The results showed that the SnO2 nanorods with 10–20 nm diameter and several micrometers length were rutile structure. The results of H2 temperature-programmed reduction demonstrated that the SnO2 nanorods had good redox performance. The redox mechanism was discussed in detail.

Key words: tin dioxide, nanorod, temperature-programmed reduction, redox property, catalytic activity, redox mechanism
