One of the major challenges in creating devices with core-shell nanotubular heterostructures has been the coating of conformal nanolayers inside the open volume of a nanoporous template. Here we show two facile assembly strategies developed, utilizing either electrochemical or solvothermal methodology, for the successful synthesis of novel SnO2@TiO2 coaxial nanotube arrays (SnO2@TNTs). Remarkably enhanced Li+ ion storage performance of the prepared nanohybrids with favorable and well-defined tubular structures is demonstrated to be derived from the synergistic effect with improved electronic conductivity and dual lithium storage mechanism, which highlights their potential as a new alternative material for electrochemical energy storage.
