Abstract: Cathodic electrochemical deposition method was introduced for the preparationof ZnO or
NiO structures on ITO glass. Via using 3D colloidal crystal templates, two-dimensionally ordered
microporous ZnO nanosheet were fabricated. Several methods were employed to test its
electrochemical properties including scanning electron microscopy and cyclic
-dimensionally (2D) ordered microporous Ni nanosheet was prepared by Nickel
plating bath via using microporous ZnO nanosheet or polymer colloidal crystal as
microstructures of such posites were characterized by SEM. Electrochemical properties
studies were carried out using cyclic votalmmetry with the aids of KOH solution. The
capacitance of 2D NiO nanomeshes arrays was about .
