Electrochemical Redox Behavior of Ni Nanowire Electrode and Its Application to Catalysis of Electrooxidation of Ethanol

The Ni nanowire electrodes were fabricated by using porous alumina as a template. The electrodes possess high redox current density, high discharge capacity and good redox reversibility in 1 mol/L KOH solution, showing its potential application as an excellent battery electrode. Experimental results also revealed its good catalytic activities for electrooxidation of ethanol in an alkaline medium.
