Metallic glass / amorphous metal electrodes produced by rapid solidification (i) having a structure that is either amorphous or nanocrystalline, (ii) containing the principal alloying element as Ni, (iii) containing alloying additions of Co and at least one member of group IVB, VB, VIB, VIIB and/or VIIIB, preferably Cr and V, in the range of 0 to 20 at. %, and when combined with Ni, represent 0.75 to 0.85 of the atomic fraction of the alloy, and (iv) containing metalloid elements comprised preferably of one or more of the elements C, B, Si and P either singly or in combination to represent 0.15 to 0.25 atomic faction of the alloy. The electrodes have excellent thermal stability, improved stability in an aqueous electrolyte and can provide improved current efficiency - anodic overpotential performance. They are used in the electrolysis of aqueous electrolyte solutions such as mixtures of caustic and water in the production of oxygen and hydrogen. |
