Metal alloy for electrochemical oxidation reactions and method of production thereof

摘要

A method of producing a finely divided ruthenium-platinum alloy catalyst comprising: (i) forming a mixture of platinum &bgr;-diketone and ruthenium &bgr;-diketone on a carbon support, (ii) both, platinum &bgr;-diketone and ruthenium &bgr;-diketone having a decomposition temperature within 20° C. of each other, (iii) decomposing said platinum &bgr;-diketone and ruthenium &bgr;-diketone on a carbon support at a temperature of at least 260° C. in the absence of a reducing agent (iv) followed by a reduction effected with a hydrogen containing gas mixture and a method from oxidizing methanol.
