Abstract
A method for preparing a multi-component alloy catalyst on which a catalytic metal is supported includes preparing a carbon composite having a carbon support coated with a cationic polymer, supporting a catalytic metal containing at least two metal elements on the carbon composite to prepare an alloy catalyst precursor, and washing the alloy catalyst precursor to remove the cationic polymer.
