Abstract
Niobium oxide exists in several crystal phases and valence states, yielding a variety of properties. Phase transitions between polymorphs significantly alter the properties of functional niobium oxide nanostructures, which are applied in many different renewable energy applications. This study uses environmental transmission electron microscopy to investigate the oxidation of NbO nanowires to T-Nb2O5. Small oxygen partial pressures (
