The present paper is focused on comparative behavior of various nanotubes growth on titanium using electrochemical procedure. The anodizing method under controlled conditions was performed in three kinds of electrolytes as following: a mixture of fluoride salts as inorganic solution (1M (NH4)2SO4 + 0.5 wt.% NH4F), and an organic solution as Glycerol + NH4F (0.5 wt.%), and a mixture of glycerol and water (1:1 vol.%) + 0.5 wt.% NH4F. The obtained surface nanostructures were investigated with a Scanning Electron Microscope, open circuit potential, Tafel plots and Electrochemical impedance spectroscopy. As a conclusion the titanium oxide nanotubes obtained in hybrid organic + inorganic components as glycerol-water (1:1 vol.%) + 0.5 wt.% NH4F leads to more performances. The presence of glycerol with water in the electrolyte can facilitate the formation of well-ordered TiO2 nanotubes. This is not observed in organic electrolyte, because the glycerol causing a greater ohmic potential drops, and the high viscosity of glycerol can suppress the formation of nanotube structure.
