One-dimensional SrSn(OH)(6) nanowires were successfully synthesized through a rapid simple method-sonochemical synthesis at room temperature without using any templates or surfactants. The growth mechanism has been proposed, and the reaction conditions were carefully investigated. The experimental results revealed that both the ultrasound irradiation and the presence of Na2CO3 in the synthetic process had an impact oil the fast formation of the SrSn(OH)(6) nanowires. Moreover, a subsequent precipitation-hydrothermal treatment of SrSn(OH)(6) nanowires-was conducted in ethanol at 180 degrees C for 8 h in order to improve their crystallinity and thermal stalibity. SrSnO3 nanorods were converted by calcination of the hydrothermally treated SrSn(OH)(6) nanowires at 700 degrees C for 3 h in air. In particular, it was the first attempt to test the electrochemical properties of the SrSnO3 products as anode in a Li ion battery. The resulting SrSnO3 nanorods exhibited a better cyclability over 50 cycles with a reversible lithium storage capacity of 200 mA h g(-1) than that of SrSnO3 nanoparticles.
