Patent ID: 8491697

Claim:
A method for producing an electrocatalyst, comprising the steps of: preparing a reverse micelle solution by mixing two or more catalyst precursors selected from among metal salts and/or metal complexes, a solvent having hydrophilic groups and a non-aqueous solvent, in a state that the two or more catalyst precursors are mixed uniformly and enclosed together in single reverse micelles in the single reverse micelle solution; and forming alloy particles from the two or more catalyst precursors selected from among metal salts and/or metal complexes in the reverse micelles by adding a reducing agent solution comprising LiB(C 2 H 5 ) 3 H to said reverse micelle solution and heating to promote a reduction reaction; after heating to promote the reduction reaction, treating the reverse micelles surrounding the alloy particles with a solvent comprising a lower alcohol to partially remove the reverse micelles; uniformly supporting said alloy particles from which the reverse micelles are partially removed on a carrier; and removing components of the reverse micelles from the alloy particles by heating the alloy particles supported uniformly on the carrier under an inert gas.
