Shape Evolution of New-Phased Lepidocrocite VOOH from Single-Shelled to Double-Shelled Hollow Nanospheres on the Basis of Programmed Reaction-Temperature Strategy

We report a new and convenient route to synthesizing double-shelled hollow spheres from solid templates only by programming the reaction-temperature procedures. The complex hierarchitecture of new-phased lepidocrocite VOOH provides prospective signs for using designed porous nanoarchitectures in future smart-house systems.
