Controlled synthesis of skein shaped TiO2–B nanotube cluster particles with outstanding rate capability

Abstract

Herein, we first report a facile synthetic route for preparing micron-sized particles comprising TiO₂–B nanotubes, namely, skein shaped TiO₂–B nanotube cluster particles with an ultra high surface area of 257 m² g⁻¹. The galvanostatic charge–discharge test showed that the hierarchical micron-sized particles composed of TiO₂–B nanotubes with approximately 10 nm in diameter exhibited outstanding rate capability as well as high specific capacity.
