Amorphous alloy electrodes for electrochemical oxidation of methanol and its derivatives were obtained by the surface activation treatment consisting of electrodeposition of zinc on as-quenched amorphous alloy substrates, heating at 200-300℃ for 30 min, and subsequently leaching of zinc in an alkaline solution. The surface activation treatment provided a new method for the preparation of a large surface area on the amorphous alloys. The best result for oxidation of methanol, sodium formate and formalin was achieved by using the surface-activated amorphous palladium-base alloys. The activity is varied with heat treatment temperature in the surface activation treatment, and metallic and metalloid additives. The beneficial alloying elements were phosphorus, nickel, platinum, rhodium and ruthenium.
