In this work is reported the synthesis of nanotubes and nanoribbons from
mixed oxides (Ti(1-x) Zr (x) O(2)center dot nH(2)O), employing
hydrothermal treatment in a highly alkaline medium. The morphology and
crystal structure of the products obtained via hydrothermal treatment
depend on the value of x. For example, for x equal to 0 and 0.50 were
observed the presence of nanotubes (diameter around 9 nm) and
nanoribbons (diameter around 200 nm), respectively. However, for x
values above 0.50, there was no morphological change. Regarding the
crystalline structure of these samples, for x equal to 0 was observed
the sodium titanate phase; already for x values up to 0.50, we observed
the presence of two crystalline phases: sodium titanate and tetragonal
ZrO(2). For x values above 0.50, only tetragonal ZrO(2) was observed.
Furthermore, only the product obtained from x equal to 0.15 was observed
the presence of three-dimensional flower-like arrangements. The results
obtained by the characterization techniques showed the segregation of
zirconium after hydrothermal treatment of precursors with x less or
equal to 0.50. Thus, we describe the important role that Ti/Zr molar
ratio of the precursor plays on the morphology and crystalline phase of
the products formed by hydrothermal treatment.
