In the present work, 3D/2D porous anodic alumina (PAA) templates have been fabricated from doped aluminum films (Al-0.5wt.% Cu and Al-1.0wt.% Si) by the one-step anodization method. Furthermore, Ni nanowires array and nanowires network were synthesized by pulse electrochemical deposition using the prepared 3D/2D PAA templates. The structures and morphologies of as-prepared alumina films and Ni nanowires are characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The grown Ni nanowire on Al-0.5Cu/Al-1Si template is revealed more strength and larger surface area than grown Ni on Al-1Si template. The diameter of the nanowires is about 50-70 nm with length 3 µm. The existence of Al-0.5Cu layer on the top of Al-1Si film is increase the branching degree of pores in Al-1Si layer. The resulting 3D Ni nanowire lattice provides enhanced mechanical stability and an increased surface area, which is interesting for energy storage and many other applications which utilize large surface area.
