Fine-tuning of Vanadium Oxide Nanotubes

The formation of vanadium oxide nanotubes (VOx-NTs) is sensitive to agitation during hydrothermal synthesis. The ordering of the VOx layers is lower and the interlayer distance increases. The pH range for VOx-NT synthesis could be extended to pH values below 5. At low pH, the VOx layers are better o...

Zusammenfassung:The formation of vanadium oxide nanotubes (VOx-NTs) is sensitive to agitation during hydrothermal synthesis. The ordering of the VOx layers is lower and the interlayer distance increases. The pH range for VOx-NT synthesis could be extended to pH values below 5. At low pH, the VOx layers are better ordered and there is a trend towards shorter tubes. Below a critical pH around 4.5, other morphologies next to VOx-NTs appear. Only amine templates were found to be suitable while platelets and “star-like” VOx nanomaterials were obtained using alcohols and thiols.
