Vapor-Solid Reaction Growth of Rutile TiO₂ Nanorods and Nanowires for Li-Ion-Battery Electrodes.

ABSTRACT: A new synthetic method to grow O-deficient rutile TiO_2(s) nanorods (NRs) and nanowires (NWs) by a vapor-solid reaction growth method is developed. TiCl_4(g) was employed to react with commercially supplied CaTiO_3(s) (size 2-4 μm) at 973 K under atmospheric pressure to generate TiO_2(s) NRs (diameters 80-120 nm, lengths 1-4 μm). The reaction employing TiCl_4(g) and CaO_(s) at 973 K also generated CaTiO_3(s) (size 4-13 μm) as the intermediate which reacted further with TiCl_4(g) to produce NWs (diameters 80-120 nm, lengths 4-15 μm). This is the first report of 1D rutile TiO_2(s) nanostructure with such a high aspect ratio. Both of the NRs and the NWs, with compositions TiO_1.81 and TiO₁
