Analysis of Polymorphic Nanocrystals of TiO2 by X‐Ray Rietveld Refinement and High‐Resolution Transmission Electron Microscopy: Acetaldehyde Decomposition

Journal of Nanotechnology, Volume 2008, Issue 1, 2008., 2008
In this work, TiO2 nanocrystals were synthesized by the sol‐gel method. These materials were annealed at 200 and 500∘C; and characterized by the XRD‐Rietveld refinement; and by BET and TEM. As for the low‐temperature‐treated sample (200∘C), nanocrystals with small crystallite sizes (7 nm) and high abundance of anatase, coexisting with the brookite ...
