Synthesis of highly ordered LiNiO2 nanowire arrays in AAO templates and their structural properties

LiNiO 2 nanowire arrays were prepared with porous anodic aluminum oxide (AAO) templates from sol–gel solution containing Li(OAc) and Ni(OAc) 2 . Electron microscope results showed that uniform length and diameter of LiNiO 2 nanowires were obtained, and the length and diameter of the LiNiO 2 nanowires are dependent on the pore diameter and the thickness of the applied AAO template. X-ray diffraction (XRD) and electron diffraction investigations demonstrate that the LiNiO 2 nanowires have the layered structure of LiNiO 2 . X-ray photoelectron spectroscopy (XPS) analysis indicates that a nearly stoichiometric layered LiNiO 2 material has been obtained.
