Abstract

Self-ordered TiO2/Nb2O5 “superlattice” nanotube arrays are successfully fabricated by electrochemical anodization from a commercially available Ti–Nb metal multilayer. The oxide nanotube walls then consist of alternating ∼4 nm TiO2 and ∼7 nm Nb2O5 rings. Such “superlattice” nanotube layers exhibit a much higher structural cycling stability for reversible Li-intercalation processes than pure TiO2 nanotubes.
