1. a kind of preparation method of the ultra-dispersed noble metal electrocatalyst of high stability, low-load amount, comprises the following steps that:



  • 1)

    The preparation of catalyst precarsor:

    Using the noble metal platinum of low content, palladium, ruthenium, iridium as catalytic active component, inexpensivelyIron, tin, cobalt, nickel, copper as sacrificial metal component, alloying pellet is synthesized by hydro-thermal method, alcohol reduction method or hydrazine reduction method, andBy the anchoring used load of functionalized carbon carrier on the functionalized carbon carrier of Heteroatom doping, catalyst precarsor is obtained;



    2)

    The preparation of catalyst:

    After the catalyst precarsor of above-mentioned preparation is etched with acid solution immersion treatment, with ultra-pure water repeatedlyWashing filters, is dry to get efficient ultra-dispersed noble metal electrocatalyst.
