Discharge Relaxation of TiO2-WO3 Composite Nanotube Arrays

Article Preview

Abstract:

Smooth and aligned TiO2-WO3 composite nanotube arrays (TiW-NTA) were successfully fabricated on a Ti-W alloy via an anodization process. The crystal phase and surface morphology of the nanostructured film were characterized by X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). The photoelectrochemical properties of the as-prepared samples were studied by measurement of the photocurrent response and open-circuit potential. The TiO2-WO3 nanotube arrays were found to be capable of a more than 2.5h discharge relaxation due to its energy storage behavior.
