| Description
| - Nanostruktury z oxidu titaničitého byly připraveny v autoklávu z TiCl4 a 10 M NaOH při 250oC a následným opracováním ve vodném a kyselém prostředí. Rentgenová difrakce a Ramanova spektroskopie dokazují přítomnost anatasu jako hlavní komponenty, avšak většina materiálů obsahují další složky, které se neprojevují na rtg difrakci. Cyklická voltametrie inserce lithia prokázala přítomnost dvou párů reversibilních pseudokapacitních maxim (S-maxim), která doprovázejí obvyklá maxima difuzí řízené inserce lithia. S-maxima se objevují u materiálů, které mají morfologii nanodestiček nebo nanotub. U těchto materiálů se uplatňují efekty kvantové velikosti částic. Nanodestičky jsou redukovatelné butyl lithiem až na LiTiO2. Za obodnbých podmínek poskytuje nanokrystalický anatas pouze orthorombický Li0.5TiO2. (cs)
- Nanostructured titania materials were prepared from TiCl4 via autoclaving in 10 M NaOH at 250oC and subsequent treatment in aqueous and/or acidic media. XRD and Raman spectroscopy evidenced the presence of anatase as the main phase, but most materials contained also some XRD-silent component. Cyclic voltammograms of lithium insertion demonstrate two pairs of reversible pseudocapacitive peaks (S-peaks) in addition to the ordinary peaks of diffusion-controlled Li insertion into the anatase lattice. The occurrence of S-peaks is associated with the nanosheet- and/or nanotubular morphology of the materials. This structure developed at hydrothermal conditions via exfoliation of the layered Na+/H+ titanate precursors. The S-peaks were suggested to be the signatures of quantum-size confinement in titania nanosheets. The nanosheet-containing materials are reducible by n-butyllithium to cubic LiTiO2 (at conditions, when the ordinary nanocrystalline anatase gives only the orthorhombic Li0.5TiO2).
