Abstract

Tungsten decorated titania (WT) nanotube arrays was fabricated by electrochemical anodizing followed by chemical bath deposition in combination with a pyrolysis process. Resulting \WT\ nanotube arrays were studied as potential electrode materials for electrochemical double layer capacitor (supercapacitor) applications. The structural, morphological, and compositional characteristics of the resulting electrode materials were evaluated by using X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and energy-dispersive X-ray (EDX) spectroscopy. Results showed that titania nanotube arrays (T) with an internal diameter of the tubes around 90
