We refrain here from giving an extensive overview of studies on the surface structure of vanadium oxide nanolayers, as this has already been done for up to year 2003 in our recent review [97]. Instead, we would like to focus on prototypical examples, selected from the V-oxide-Rh(l 1 1) phase diagram, which demonstrate the power of STM measurements, when combined with state-of-the-art DFT calculations, to resolve complex oxide nanostructures. Other examples will highlight the usefulness of combining STM and STS data on a local scale, as well as data from STM measurements, and sample area-averaging spectroscopic techniques, such as XPS and NEXAFS, to derive as complete a picture as possible of the investigated system. [Pg.160]

In conclusion, these data do not allow concluding whether or not Titania nanotubes form better catalysts due to their intrinsic nanostructure, and not simply because they have a high geometrical surface area and provide a good dispersion of supported catalysts. These properties may be found in other Titania based catalysts not having a ID nanostructure. On the other hand, it is also clear from above comments that most of the studies up to now were justified essentially from the curiosity to use a novel support more than from the rational design of advanced catalysts, which use the metal oxide nanostructure as a key component to develop... [Pg.380]

Although several studies have been dedicated to analyzing the relationship between nanostructure of supported metal particles and catalytic behaviour, fewer studies have been dedicated to growing controlled oxide nanostructures and their relationship to catalytic reactivity. [Pg.82]

In addition, materials prepared by anodization permit the growth of the oxide nanostructured film over a conductive substrate (Ti foil), an important aspect for preparation of robust electrodes. As discussed later, electrical contact with the conductive substrate could be further improved using carbon nano tubes. [Pg.93]

As pointed out in part 1, ° ID oxide nanostructures do not represent only particles with high elongation ratio, but possess different spedfie eharaeteristics related to the nanostructure. For example, O2 adsorption is different from that observed for Ti02 single erystals and this has consequenees on the catalytic behaviour. In order to exploit the properties of ID oxide nanostructure, however, it is essential to orient nanotubes on substrates and to create ordered arrays. [Pg.99]

In figure 4 we show the Raman spectra of the various metal oxide nanostructures studied by us. Raman bands are found at 332,441 and 1076 cm"1 for the ZnO nanoparticles and nanorods [20], Bulk ZnO shows Raman bands at 330 and 439 cm-1 [20, 21]. The nanoparticles and nanorods of ln203 show Raman bands at 305, 364, 495 and 630 cm-1. [Pg.597]
