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. © 2007 American Chemical Society.
