title: Fabrication of highly crystalline SnNb2O6 shell with a visible-light response on a NaNbO3 nanowire core.
abstract: A visible-light-absorbing SnNb2O6 shell with high crystallinity was successfully fabricated on a NaNbO3 nanowire through a molten salt treatment of the NaNbO3 nanowire of the starting material with SnCl2, whereas the fabrication was not successful on the TT phase of a niobia nanowire. The difference will come from the formation processes of SnNb2O6 crystals (ion-exchange reaction vs thermally induced crystallization reaction). The core/shell nanowire obtained from NaNbO3 showed photocatalytic activity comparable to that of H2 evolution in the presence of an electron donor under visible-light irradiation (λ > 420 nm), compared with the corresponding bulky counterpart.
