Abstract

A fabricating method of uniformly dispersing noble metal on surface of iron particle is disclosed, comprising the steps of: providing a plurality of iron metal particles; rinsing and cleaning the iron metal particles and then processing a solid/liquid separation; drying the iron metal particles; disposing the iron metal particles into a heating reaction furnace and then introducing reaction gas into the furnace; heat reducing the iron metal particles then taking out the iron metal particles; adding the iron metal particles into a liquid containing noble metal ions then processing electrolysis-free gold-coating reaction; processing a solid/liquid separation on the reacted iron metal particles then drying, wherein the heating temperature of the heating reaction furnace is between 300 to 500 ℃ and the duration is between 3 to 5 hours; after the activity of the surface of the iron metal particles is unified, then the reaction of noble metal replacement is processed, so that the uniformity and activity of the noble metal on the surface of the iron metal particles can be increased.
