Electrooxidation of Ethanol on Nickel-Copper Multilayer Metal Hydroxide Electrode

摘要

The electrocatalytic oxidation of some alcohols is of great interest due to a wide range of application. The reaction is used not only in electrosynthesis of organic compounds but in direct alcohol fuel cells (DAFCs) too. Fuel cells require highly reactive fuels with high-energy density and low toxicity [1-4]. One of the key points to develop a cost-effective electrolysis is to decrease the cost of electrocatalysts for the oxidation. The commercial use of highly effective catalysts containing Pt and Pd is limited due to having high cost and global scarcity [5]. Alkaline electrolytes allow the use of inexpensive transitional metals and metal oxides. Such electrolytes have higher efficiency of both anodic and cathodic processes. There is almost no sensitivity to the surface structure and negligible poisoning effects in alkaline solutions [4].
