Engineered Ptshell-Pdcore bi-metallic catalyst for active and durable alcohol oxidation in direct-fuel fuel cells |
| 초록 |
Pt-Pd nanoparticles are structure-engineered by successive electroless deposition and galvanic displacement technique, to manifest a shell-core configuration. When applied as an electrocatalyst, they are confirmed to be highly active toward both methanol and ethanol oxidation reaction for a prolonged time. The stable activity of Pt-Pd catalyst is ascribed to the surface-tuned electronic property of Pt over-layer, which leads to a weak adsorption strength to CO and a high affinity to OH. The observed chemical stability of as-prepared catalyst is further proved and supplemented by a computational investigation via density functional theory calculation. The experimental and theoretical outcomes indicate that the catalyst is suitable and applicable for the direct methanol and ethanol oxidation in DAFC. |
