METHOD FOR PREPARATION OF A SUPPORTED NOBLE METAL-METAL ALLOY COMPOSITE, AND THE OBTAINED SUPPORTED NOBLE METAL-METAL ALLOY COMPOSITE

摘要

The present invention concerns a double passivation galvanic displacement (GD) synthesis method for production of high performance, supported noble metal-M alloy composite material, where M is an electrochemically less noble metal, compared to the noble metal, the supported noble metal-M alloy composite material obtained by the synthesis, and the use of such composite material as electrocatalyst material.
