Abstract :
The present research aimed to evaluate the effects of synthesis parameters on morphology and photocatalytic activity of TiO2 nanotube aligned arrays (TNAs) via a low-cost anodization process. The impact of electrolyte composition, anodization time, and applied voltage on morphological and architecture properties of TNAs, including length, inner diameter and wall thickness, were accurately investigated. We further studied the effect of heat treatment on crystalline and phase transformation of the samples at different annealing temperatures. Photocatalytic properties of the fabricated samples were studied for degradation of p-nitrophenol under UV light irradiation. The physicochemical characteristics of the photo-anodes were observed using several techniques including field emission scanning electron microscopy, energy dispersive X-ray spectroscopy and XRD. Moreover, the maximum photocatalytic performance for p-nitrophenol degradation was obtained as about 80%.
