The use of titanate nanowires as advantageous substrates for the development of hybrid photocatalysts are herein reported, considering TEM, XRD and Raman for an in-depth characterization of the chemical and structural properties of these objects. These titanate nanowires functionalized with Au nanorods and TiO2 nanoparticles offer  a new class of hybrid nanostructures with outstanding photocatalytic features. These extraordinary properties are explained as a consequence of the anisotropic morphology of the substrates and the preferential directed 1D assembly of the Au nanorods, thus leading to the controlled formation of plasmonic hot spots.
