Synthesis of highly ordered LiMnO2 nanowire arrays (by AAO template) and their structural properties

LiMnO₂ nanowire arrays were prepared using a porous anodic aluminum oxide (AAO) template from a sol–gel solution containing Li(OAc) and Mn(OAc)₂. Electron-microscope results showed that a uniform length and diameter of LiMnO₂ nanowires were obtained, and the length and diameter of the LiMnO₂ nanowires are dependent on the pore diameter and the thickness of the applied AAO template. X-ray diffraction and electron diffraction pattern investigations demonstrate that LiMnO₂ nanowires are a layered structure of LiMnO₂ crystal. X-ray photoelectron spectroscopy analysis indicates that a material closely resembling stoichiometric layered LiMnO₂ has been obtained.
