Design of Au core-Palladium alloy shell nanoparticle for oxygen reduction reaction in Fuel cells |
| 초록 |
Platinum based nanomaterials are usually used as the electrocatalysts for both the cathode(oxygen reduction) and anode(hydrogen oxidation) reactions. However, the high cost of Pt in cathode catalyst and the slow kinetics of oxygen reduction reaction (ORR) on Pt-based catalysts hinder the commercialization of fuel cells. Instead of using platinum, recent studies have focused on the discovery of non platinum electrocatalysts which have excellent electrocatalytic activity and chemical stability. In this study, we synthesized gold core/palladium-Cobalt alloy shell catalysts. The developed catalysts showed excellent catalytic activity than Au core/Pd shell catalysts. The structural information and electrocatalytic activities of the Au core/Pd-Ir alloy shell nanoparticles were analyzed by XRD, XPS, HR-TEM, ORR test and cyclic voltammetry(CV). |
