摘要: A new procedure for preparing free-standing nanowire arrays is described. This based on a template method which entails electrochemical metal deposition into nanometer-wide parallel pores of porous anodic oxide films aluminum. By varying the preparation conditions and by applying posttreatment methods, gold are prepared, whose morphological dimensional properties oxygen content in surface can be varied investigated SEM XPS-characterization. The voltammetric behaviour such shows significant enhancement ratio between total electrolytically exposed area diffusionally accessible comparison with macroscopic flat electrodes.
