TiO2 nanocages : fast synthesis, interior functionalization and improved lithium storage properties

Abstract

High-quality anatase TiO2 nanocages with anisotropic shapes, homogeneous shells and tunable sizes can be fabricated by templating against Cu2O polyhedra under hydrothermal conditions. The interiors of these TiO2 nanocages can be functionalized easily with Au nanoparticles. The promising use of these TiO2 nanocages as an anode material for lithium-ion batteries is also demonstrated.
