Abstract

Highly ordered anodic single-walled TiO₂ nanotubes (SW-TiO₂ NTs) and double-walled TiO₂ nanotubes (DW-TiO₂ NTs) are prepared in the unique NH₄BF₄ based electrolyte. The formation of SW-TiO₂ NTs and DW-TiO₂ NTs can be simply tuned by the voltages. The DW-TiO₂ NTs show higher photoelectrochemical performance than the SW-TiO₂ NTs.
