Abstract
In-doped Bi2Se3 hierarchical nanostructures have been synthesized by an in situ cation exchange route from their template of In 3Se4 nanostructures. Through detailed structural, chemical, and morphological characterizations, it has been found that, after the cation exchange, the In-doped Bi2Se3 hierarchical nanostructures preserve the morphology of original In3Se4 thin nanosheet-assembled nanostructures, and the layer structure transforms from 7 atomic layers of 'Se-In-Se-In-Se-In-Se' into 5 atomic layers of 'Se-Bi-Se-Bi-Se'. The electrochemical measurements reveal that the synthesized In-doped Bi2Se3 hierarchical nanostructures show much better discharge capacity, improved cycle stability, and rate performance as an anode material for Li-ion batteries compared to its undoped counterparts.
