| Sumario: | Amorphous alloys (Co<sub>94.6</sub>P<sub>5.4</sub> and Co<sub>71.6</sub>Ni Is<sub>18.3</sub>aP<sub>10.1</sub>) were prepared by the eleetroless teehnique. Oxide coated amorphous alloys were produced by applying a cyclic potential routine to the amorphous alloys immersed in alkaline solution at 30°C. Oxide coatings were character&d by electrochemical techniques and ir spectroscopy. The electrocatalytic activity of oxide coated amorphous alloy electrodes was tested for the oxygen evolution reaction in alkaline solution at 30°C. The high electrocatalytic activity of these electrodes is explained through the development of a porous hydrous oxide film with a spinel-type structure. |
