Abstract
Nickel electrode with nanostructured mesoporous properties has been fabricated by electrodeposition of a nickel(II) solution dissolved within the lyotropic liquid crystalline phases of Brij 78 non-ionic surfactant in the hexagonal form (III). Cyclic voltammetric investigation has shown that these materials have high surface areas and a pore structure that allows extremely fast diffusion of species to active sites within the structure. The electrochemical results were further verified by X-ray diffraction and transmission electron microscopy techniques.
