Abstract

We demonstrate that the use of poly(vinyl pyrrolidone) (PVP) and acetic acid during the synthesis of TiO₂ nanotubes may result in the synthesis of single-crystal-like anatase TiO₂ with a mainly exposed and chemically active (001) facet. An enhancement in the overall conversion efficiency of dye-sensitized solar cells was observed in a photoanode consisting of TiO₂ single-crystal-like anatase exposed (001) facets.
