Descripción
Sumario:TiO(2)/WO(x) nanotubes have unique photo-energy retention properties that have gathered scientific interest. Herein, we report the synthesis, morphological characterization, and the electrochemical characterization of TiO(2)/WO(x) nanotubes compared with pure TiO(2) nanotubes, prepared by anodization technique. Significant structural differences were not observed in TiO(2)/WO(x) nanotubes as observed by using scanning electron microscopy and transmission electron microscopy. The charge transfer resistance of TiO(2)/WO(x) before and after photo irradiation determined by using electrochemical impedance spectroscopy proves the inherent energy retention property which was not observed in pure TiO(2) nanotubes.
