Abstract
The present document provides details of a nanostructured material defined by an anodized alumina having a nanostructure with transverse pores that pass through and connect longitudinal pores grown on an aluminum substrate. This document also describes the process for producing said nanostructured material and the possible use thereof as a template or mould for obtaining nanostructures formed by nanowires, which are generated in the cavities or pores of the aforementioned nanostructure of the nanomaterial of the invention. Likewise, this document details the use of the nanostructured anodized alumina material as a mould for producing nanostructures.

- pulse mild anodizing stages with fixed potential, and
- current-limited pulse hard anodizing stages,
- growing at least one nanostructured anodized material layer on the substrate as a consequence of the preceding step, said layer corresponding to the anodized nanostructured material, and
- carrying out a chemical attack to reveal the transverse pores.
