▎ 摘  要

NOVELTY - Producing metal nanoparticles having carbon shell comprises (a) pre-treating the support or carrier; (b) forming a polymer layer on the pretreated support or support; (c) adsorbing a metal precursor to the polymer layer; and (d) heat-treating the adsorbed metal precursor. USE - The metal nanoparticles are useful as metal catalyst i.e. alloy catalyst (all claimed) for fuel cells, water electrolysis, batteries, and solar cells. ADVANTAGE - The the nanoparticles can be: uniformly supported on the carrier; and produced in simple manner. The carbon shell prevents aggregation of nanoparticles and elution of metals that occur during fuel cell operation, so that ensuring high stability and durability. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the method for producing metal nanoparticles having carbon shell (Drawing includes non-English language text).
