The present application relates to a method for preparing an amorphous platinum alloy. The method for preparing an amorphous platinum alloy comprises the following steps: melting a transition metal and platinum into a cast ingot in an inert gas atmosphere; removing an oxide layer from the surface of the cast ingot; and carrying out melt spinning on the cast ingot to obtain an amorphous platinum alloy.

The multi-metal composition of the amorphous platinum alloy can improve the catalytic performance by means of an alloying effect, and compared with a conventional crystalline alloy catalyst, the interior of the amorphous alloy is lack of a structural defect causing easy electrochemical corrosion, so that an oxidation-resistant potential of 0.8 V or more can be achieved; in addition, the performance attenuation rate can also be minimized after polarity reversal occurs, and failure would not easily occur at a high potential. Therefore, the amorphous platinum alloy can serve as a fuel cell catalyst with lower cost and better durability.
