Arrays of Ni(OH) 2 and Fe‐doped Ni(OH) 2 tubes were successfully prepared by electrochemical deposition in porous alumina membranes under ambient conditions. Extensive analysis of the tubes was carried out by X‐ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and high‐resolution transmission electron microscopy (HRTEM) equipped with energy dispersive spectroscopy (EDS), and X‐ray photoelectron spectroscopy (XPS). The results show that the electrodeposition method yielded uniform Ni(OH) 2 and Fe‐doped Ni(OH) 2 tubes with inner diameters of 150–180 nm, wall thicknesses of 20–30 nm, and lengths of about 60 μm. This template‐based electrochemical deposition method can be extended to the synthesis of other similar materials such as micro‐ or nanotubes, ‐wires, and ‐rods. Furthermore, the Ni(OH) 2 and Fe‐doped Ni(OH) 2 tubes may have promising applications in alkaline rechargeable batteries and electrocatalytic electrolysis for the production of hydrogen.
