NOVELTY - Manufacturing metal nano-catalyst, comprises dissolving the metal precursor in a polar solvent; preparing a mixture in which a solution in which the metal precursor is dissolved and an ionic liquid are mixed; and irradiating the mixture with microwaves. USE - The method is useful for manufacturing metal nano-catalyst. ADVANTAGE - The method manufactures metal nano-particles of uniform size by irradiating microwaves to a metal precursor uniformly dispersed in an ionic liquid to supply uniform energy.
