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.

Method for manufacturing core-shell catalyst using carbon monoxide

An electrode catalyst is configured such that non-noble metal particles, noble metal particles or nitride-doped noble metal particles are supported on a carbon support, wherein the carbon support has a 2D planar crystal structure or a 3D polyhedral crystal structure and is doped with nitrogen, thereby exhibiting increased catalytic activity.

Method for manufacturing core-shell particles using carbon monoxide

The present invention relates to a transition metal nitride support, a method of manufacturing the same, a metal catalyst and a platinum-alloy catalyst including the transition metal nitride support, and manufacturing methods thereof. The manufactured transition metal support prevents corrosion of the support and aggregation of the platinum catalyst, thereby exhibiting high oxygen reduction catalytic activity. Also, strong metal-support interaction (SMSI) can be stabilized, thus improving the durability of the catalyst. The transition metal support includes large pores uniformly distributed therein, thereby increasing the amount of the catalyst supported and minimizing mass-transfer resistance in a membrane- electrode assembly, increasing the performance of a polymer electrolyte membrane fuel cell. The metal catalyst includes platinum particles loaded on the transition metal nitride support, thus exhibiting superior durability and activity. The manufactured platinum-alloy catalyst decreases the use of expensive platinum, thus generating economic benefits and improving the inherent oxygen reduction performance.
