|Title:||Polycrystalline SnO 2 nanotubes prepared via infiltration casting of nanocrystallites and their electrochemical application||Authors:||Wang, Y.
|Issue Date:||26-Jul-2005||Citation:||Wang, Y., Lee, J.Y., Zeng, H.C. (2005-07-26). Polycrystalline SnO 2 nanotubes prepared via infiltration casting of nanocrystallites and their electrochemical application. Chemistry of Materials 17 (15) : 3899-3903. ScholarBank@NUS Repository. https://doi.org/10.1021/cm050724f||Abstract:||In this work we demonstrated that uniform polycrystalline SnO 2 nanotubes, in either array or free-standing form, can be fabricated by an infiltration technique using SnO 2 nanoparticles as starting building units. With this method, the diameter, length, thickness, and texture of the nanotubes can be further controlled. The tubular SnO 2 shows a significant improvement of electrochemical performance over the unorganized nanoparticles. The specific capacity of the Sn-based nanotube electrode was 525 mAh/g after 80 cycles. In principle, the tubular structure of active component can also be extended to other metal oxides and Li-metal alloy systems. In view of their unique features, the prepared SnO 2 nanotubes may also find interesting applications in other fields such as gas sensing. © 2005 American Chemical Society.||Source Title:||Chemistry of Materials||URI:||http://scholarbank.nus.edu.sg/handle/10635/89835||ISSN:||08974756||DOI:||10.1021/cm050724f|
