Preparation And Electrochemical Property Of Aao Nano-Channels Filled With Nio, Chi Gu, Jun-Mei Yan, Yong Yang
Journal of Electrochemistry
The AAO template with nano-channels was synthesized and filled with transient metal-oxide NiO by sol-gel method, and their electrochemical properties were primarily studied. The results showed that the porous nano-channels were well defined with the diameter about 50nm. The nano-structured NiO was filled into the template's nano-channels successfully., Cyclic voltammetry studies show that the NiO in AAO template has good cycle stability.It was suggested that the AAO-metal-oxides composites could be used as novel anode materials for Lithium ion battery.

An improved technique for fabrication of carbon nanotube array electrodes has been proposed in this work. Firstly, carbon nanotubes (CNs) array electrodes were prepared by combsination of Chemical Vapor Decomposition (CVD) method and sputtering techniques in anodized aluminum oxide (AAO) membrane. The CNs/AAO was immersed into HF solution to remove the barrier layer. Controlling the immersing time, the CNs array electrodes with different length contacted with electrolyte can be prepared. The morphology of CNs array electrodes was observed by SEM. The electrochemical properties of CNs array electrodes were investigated by cyclic voltammetry and electrochemical impedance spectroscopy. Cyclic voltammetric curves of …
