Abstract: The present disclosure relates to a method for manufacturing core-shell particles using carbon monoxide, and more particularly, to a method for manufacturing core-shell particles, the method of which a simple and fast one-pot reaction enables particle manufacturing to reduce process costs, facilitate scale-up, change various types of core and shell metals, and form a multi-layered shell by including the steps of adsorbing carbon monoxide on a transition metal for a core, and reacting carbon monoxide adsorbed on the surface of the transition metal for the core, a metal precursor for a shell, and a solvent to form particles with a core-shell structure having a reduced metal shell layer formed on a transition metal core.
