A Novel Process to Produce Nano Porous Aluminum Oxide Using Alkaline Sodium Phosphate Electrolyte

Abstract: In this study, we report the fabrication of nano porous aluminum oxide film for the first time, in alkaline sodium phosphate electrolyte at ambient temperature using a single step anodization approach. A novel method has been developed to prepare the electrolyte, by simply titrating the phosphoric acid with a base for preparation of new types of Anodized Aluminum Oxide (AAO) at pH 13. The anodization process was controlled by a dc voltage of 20 V applied across the electrochemical cell. Using this method, we have been able to obtain nano porous aluminum oxide with pore diameters between 50-100 nm. Apart from the influence of the current density, traces of sodium and phosphorus present in the porous alumina also makes a significant contribution to the formation of nano pores.
