Abstract

The nanoscroll-to-nanotube thermal transformation was studied for H ₄Nb ₆O ₁₇·4.4H ₂O scrolls, prepared by exfoliation of K ₄Nb ₆O ₁₇. Thermal dehydration of the scrolls produces Nb ₂O ₅ nanotubes at 400-450°C. The nontopochemical transformation results in polycrystalline nanotubes; however, significant texturing with respect to the tube axis is observed. Substituting Ta for Nb in the precursor compound led to a lower yield of scrolls, most likely because there is less built-in lattice strain to drive scrolling of the unilamellar colloidal sheets.
