Over the last years, the synthesis of self-organized nanostructures materials has attracted a great scientific and technological interest due to its far-reaching and innumerable applications including renewable energy, sensors, biomedical devices and energy storage. Among these nanostructured materials, self-organized TiO2 nanotubes (TiO2 NTs) and Porous Silicon (PS) layers obtained by electrochimical anodization process of Titanium (Ti) foil and Silicon (Si) wafers respectively, exhibits a high porosity and larger specific area offering an enhancement in their properties. In the present study, we investegate the synthesis process and morphological properties of both structure TiO2 NTs and PS layers through anodic current in fluoride appropriate electrolyte. Thereafter, a brief reminder of the technological applications of these two materials.
