Abstract
Disclosed is a method of forming a cathode by electroplating a sacrificial metal and a catalytic metal from an electroplating solution onto an electroconductive substrate. Initial electrodeposition is carried out at a high temperature to preferentially electroplate the catalytic metal, the electroplating solution is then cooled, and thereafter the electrodeposition is carried out at a lower temperature to codeposit sacrificial metal and catalytic metal. Also disclosed is an electrode prepared thereby.
