A novel
photoelectrode of three-dimensional (3D) lupinus-like TiO<sub>2</sub> nanorod@Sn<sub>3</sub>O<sub>4</sub> nanosheet hierarchical heterostructured
arrays (TiO<sub>2</sub>@Sn<sub>3</sub>O<sub>4</sub> HHAs) on a transparent
F-doped SnO<sub>2</sub> glass substrate was designed and fabricated
by a two-step solvothermal growth process. Photoelectrochemical (PEC)
measurements showed that the 3D lupinus-like TiO<sub>2</sub>@Sn<sub>3</sub>O<sub>4</sub> HHAs photoelectrode displayed enhanced photocurrent
density (3-fold increase with respect to that of pure TiO<sub>2</sub>), improved conversion efficiency, more negative onset potential
(from −0.13 to −0.33 V vs normal hydrogen electrode),
and higher light on/off cycle stability. The improved PEC properties
may be ascribable to the enhancement of light harvesting and large
contact area with the electrolyte by increased surface area as well
as improvement of charge transfer and collection through the synergistic
effects between band structures and morphology.
