Abstract
Metal deposited carbon cloth electrodes and metal-oxide spinel containing carbon cloth electrodes have shown in past studies to be promising components in energy storage devices [1] [2]. However, the focus is usually on the fabrication procedure that includes an oxidation step and a subsequent two-electrode characterization test in an energy storage test device. The latter may conflate with or be dependent on the stability of other components, such as the electrolyte, the counter electrode, and any other surface reactions. In this study, nickel-molybdenum and copper-tin deposited carbon cloths are fabricated and arranged in a three-electrode setup to determine conductor, semi-conductor, and electrochemical characteristics, specifically their Mott-Schottky and impedance properties, with a follow-up surface characterization by means of scanning electron microscopy. These results are to be compared to characterization results from oxide containing spinels deposited on carbon cloth electrodes fabricated in previous studies [1] [2] [3]. The results of this study intend to provide comparable information that may demonstrate the viability of electroless deposition of metals on conductive carbon as a catalytic support material without the use of an oxidation step to form oxides.
