One‐Dimensional Hierarchical Structures Composed of Novel Metal Oxide Nanosheets on a Carbon Nanotube Backbone and Their Lithium‐Storage Properties

Abstract Some facile solution methods are developed to directly grow anatase TiO 2 nanosheets with exposed (001) facets and SnO 2 nanosheets onto a carbon nanotube backbone for the first time. TiO 2 nanosheets can also be grown on SnO 2 @CNT coaxial nanocables. An electrochemical investigation shows that these unique one‐dimensional hierarchical nanostructures exhibit significantly enhanced lithium‐storage properties under different testing conditions by comparison to the pure metal oxide counterparts, and evidently suggests that improved electrochemical properties of TiO 2 and SnO 2 can be achieved through proper design of the nanostructure and chemical composition.
