Amorphous alloys for electrodes in the electrolysis which are surface-activated and consist of 10-30 atomic percent P and/or Si, 20 atomic percent or more Pd and 20-50 atomic percent Ru, Rh, Ir and/or Pt. The alloys sometimes contain further 15 atomic percent or less Ti, Zr, Nb and/or Ta. By surface activating certain amorphous alloy electrodes (generally known from GB 2051158B) their electrocatalytic activity is enhanced. The electrodes may be surface activated by diffusing zinc into the surface and then leaching the zinc from the surface. The electrodes may be used from the electrolysis of dilute sodium chloride solutions to produce sodium chlorate, for the electrolysis of bromides or of organic compounds or as electrodes in batteries or fuel cells. |
