1. A method for manufacturing core-shell particles using carbon monoxide, the method comprising steps of:
sequentially performing a primary nitrogen purge, a carbon monoxide purge, and a secondary nitrogen purge in a transition metal solution for a core; and
preparing a solution containing particles having a transition metal core and a single-layered metal shell formed thereon by adding a metal precursor for a shell to the solution in which the purges have been performed.
