Investigation of the aging effect of electrolyte on the morphology and photocatalytic properties of TiO2NTs synthesized using the anodization route

In this study, TiO2 nanotube (TiO2NT) arrays were successfully synthesized via two-step anodization in organic electrolyte solutions composed of ethylene glycol, 0.5 wt% NH4F, and 3.0 wt% H2O. The effect of aged electrolytes on the morphological and photocatalytic properties of the obtained TiO2NTs was investigated. Field-emission scanning electron microscopy, X-ray diffractometry, UV–Vis absorption spectrometry, and photoluminescence...
