ZnO Nanosheets with Ordered Pore Periodicity via Colloidal Crystal Template Assisted Electrochemical Deposition

Abstract

Two-dimensional ZnO nanosheets with ordered pore periodicity are synthesized via a colloidal crystal template assisted electrochemical deposition method. The nanosheets follow a preferable crystallization orientation along the {111} crystal plane family of the colloidal crystals. Ordered pore periodicity in free-standing ZnO nanosheets, which are deposited on the three-dimensional ZnO inverse opals, is also demonstrated.
