ELECTROCHEMICAL AND MORPHOLOGICAL CHARACTERIZATION OF ANODIZED TIO2 USED FOR BATTERY ANODES

In the last decade, low-dimensional nanostructural materials have attracted increasing scientific and technological attention due to their physical properties and their potential applications. Dimensionality has a crucial role in determining the properties and performance of nanomaterials. Therefore, the control of size and shape of nanomaterials it is of great importance. Titania nanotubes have improved properties compared to any other form of titania for applications in water and air purification photocatalysis, sensing, water photoelectrolysis for hydrogen generation, photovoltaics, photoelectrochemical solar cells, electronics and optics. In the present study, the electrochemical characteristic and morphology of anodized oxide film on cp-Ti in etilen glycol + 2%v/v H2O + 0.5wt%NH4F are investigated using potentiodynamic polarization, ac-impedance, complemented with SEM and EDX analysis examinations to predicate the suitable conditions for preparing the anodized oxide films on Ti to be good for batteries anodes. Different anodization voltages were applied to investigate the most suitable voltage required for anodization
