OPTIMIZING THE PERFORMANCE OF ION-TRANSFER AND ENERGY STORE VIA HEXAGONALLY ORDERED ALUMINA NANOPORE TEMPLATE BASED ELECTRODE
The electrochemical performances of the nickel based hexagonally ordered nanopore electrode (NE) was investigated by various pore diameters in this research. To fabricate the NE, self-organized alumina nanopore structure was used as a template. Nickel was deposited on alumina nanopore template by using E-beam evaporator. The experiments for Electrochemical Impedance Spectroscopy (EIS) and Cyclic Voltametry (CV) measurements were conducted by electropotential stat using the NE to investigate the performance of energy store and ion transfer. This study has revealed the critical parameter that can affect to electrochemical property of the NE: effective surface area (ESA). Results indicated that the hexagonally ordered NE is able to control the electrochemical reaction performance further it is desirable to design of enhanced ion transfer electrode or membrane for energy devices.
