Abstract:In the present work, we report the obtaining of nanostructured porous Nb 2 O 5 by anodizing process, with Pt, Ta, Cu, or Ti impregnation, and by magnetron sputtering process. The techniques of scanning electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy were used to evaluate the morphology, and the composition and crystalline structure of nanoporous Nb 2 O 5 . The photocatalytic activity was evaluated by electrochemical photocurrent tests under UV light illumination. Nanostructured por… Show more
