Enhanced Electrochemical Capacitance of NiO Loaded on TiO[sub 2] Nanotubes

In this paper, nanotube composites were synthesized by loading various amounts of on nanotubes. The electrochemical capacitance performance of this composite was investigated by cyclic voltammgoram, ac impedance, and galvanostatic charge-discharge tests with a three-electrode system in solution. The results of these tests prove that the three-dimensional nanotube network of offers a solid support structure for the active materials , allows the active material to be readily accessible for electrochemical reactions, and improves the efficiency of the active materials. For this reason, the nanotubes used as a support for enhance the utilization of greatly. A maximum specific capacitance of was obtained for the loaded on the nanotubes.
