Lattice Widening in Niobium-Doped TiO₂ Nanotubes: Efficient Ion Intercalation and Swift Electrochromic Contrast

Widely accommodating: Novel TiO2/Nb nanotube layers (see picture, right) are grown on a titanium–niobium alloy. Niobium doping of TiO2 enlarges the cell parameters of the anatase lattice (left; Nb green, Ti gray, O red), facilitating the intercalation of H+ and Li+ ions, and even larger Na+ ions (bl...

Zusammenfassung:Widely accommodating: Novel TiO2/Nb nanotube layers (see picture, right) are grown on a titanium–niobium alloy. Niobium doping of TiO2 enlarges the cell parameters of the anatase lattice (left; Nb green, Ti gray, O red), facilitating the intercalation of H+ and Li+ ions, and even larger Na+ ions (blue) into the lattice.
