Topotactic redox reactions of copper(II) and iron(III) salts within VOx Nanotubes Novel Cu- and Fe-containing nanotubes of composition VO1.53-2.1(C12H28N)0.21Cu0.08(H2O)0.56Cl0.01 and VO2.08-2.68 (C12H28N)0.13Fe0.19(H2O)0.33Cl0.01 have been obtained by exchange of the protonated template in dodecylamine-VOx nanotubes with Cu(II) and Fe(III) salts. The exchanged materials have quite different characteristics in respect to the parent nanotubes, namely a wider inner diameter and thinner walls, owing to reduced interlayer spacings in their multiwalled structure.
