Abstract: In the present work we demonstrate the fabrication of self-assembled and highly aligned Nb2O5 nanotubes by means of electrochemical anodization of metallic Nb at room temperature. We have investigated the effect of anodization parameters (the type and the concentration of the electrolyte, the anodization voltage and the current) on the formation of Nb2O5 nanotube arrays. The structural properties of the nanotubes as a function of annealing treatment conditions (temperature and duration) have been studied. The current-voltage characterization of the samples in the dark and under UV light illumination has been carried out. The photocurrent of the Nb2O5 nanotubes has been improved by improving their crystalline performance.
