A template and surfactant free method is developed for the fabrication of vertically aligned Ag nanorod (NR) arrays. The diameter and length of Ag NRs could be tuned through adjusting the electrodeposition time. The growth mechanism of Ag NR arrays is explored through monitoring the morphology of Ag NRs with various electrodeposition time. Because of their large specific surface area and strong surface Plasmon coupling, these Ag NR arrays are able to enhance photocatalytic reaction as well as to serve as sensitive and reproducible substrates for Raman scattering. This method could be potentially applied to prepare other metal NR arrays in a large scale which would have broad applications.
