Abstract
PURPOSE: To obtain cathode of low hydrogen overvoltage for electrolysis by the procedure in which a nonelectrolytically Co-plated Fe or Ni base plate as a cathode is subjected to electrolysis in a specific liquid to cause hydrogen to emit on the cathode surface and then heated in an oxygen atmosphere.
CONSTITUTION: Co is nonelectrolytically plated on a Fe- or Ni- based base material to obtain a cathode, and then the cathode is subjected to an electrolysis in an electrolysis in an electrolyte containing a thiocyanate or a compound with thiocarbony group to cause hydrogen to emit on the surface of the cathode. Then, the cathode is heated at a temperature of approx. 400W800°C for 0.1 to several ten hours in the atmosphere of oxygen. Thus, cathode for electrolysis which has low hydrogen overvoltage and stable potential and can withstand long-term use can be obtained.
