In the present work a study on TiO2 ordered structures was pursued using an electrolyte with low water content (glycerol containing 4% H2O). The results led to determination of two distinct states matrix structure: one nanotubes for lower values applied voltage and another nanopores higher voltage. These are interpreted three key investigation methods: potentiostatic method growth, atomic force microscopy scanning electron surface characterization.
