ABSTRACT
Due to the diversity of properties, passive films play an important role in recent and future research. In the last decades, numerous studies have been conducted involving auto-organized nanostructures of different metal oxides, which have received considerable attention due to the potential technological uses of these materials. Among others, nanostructured semiconductor oxide films obtained using optimized electrochemical conditions, and derivate composite materials, have shown interesting physicochemical properties and improved performance of luminescent modules, piezoelectric transducers, solar cells, chemical sensors and electrocatalysts.
In this chapter, the optimization of synthesis strategies, morphological and chemical characterization, as well as the (photo) electrochemical activity for antimony, copper and titanium nanostructured oxides, are described.
