Abstract

TiO₂/SnO₂ double-shelled hollow spheres are successfully synthesized by two-step liquid-phase deposition method using carbon sphere templates. The formation process of TiO₂/SnO₂ hollow spheres is discussed. The samples are characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, high-resolution transmission electron microscopy and UV-vis absorption spectroscopy. The behavior of photogenerated charges in the TiO₂/SnO₂ heterojunction structures has been investigated through surface photovoltage spectroscopy. The TiO₂/SnO₂ hollow spheres which are realized show significantly enhanced photocatalytic activities, with respect to the cases of SnO₂ and TiO₂ hollow spheres. Furthermore, TiO₂/SnO₂ hollow spheres show good recyclable photocatalytic activities.
