NANOPARTICLES CONTAINING IRIDIUM HAVING A CORE/SHELL STRUCTURE AND CATALYSTS CONTAINING IRIDIUM FOR FUEL CELLS |
摘要 |
PURPOSE: An iridium contained nano-particles having a core and shell structure and a iridium dipped catalyst for fuel cells are provided to improve performance of the catalyst and fuel cells by including Pt and Ir in a nano-particle at optimal range of atomic ratio. CONSTITUTION: An iridium contained nano-particles includes a core and shell. The core includes Ir metal, and the shell includes Pt metal. The atomic ratio of the Pt and Ir within the nano particle is 0.1:1-10:1. The metal is supported by carbon. The catalyst for fuel cells is nano-particle. A manufacturing method of the nana-particles comprises the following steps: forming IrOx nano-particles on the carbon; forming Ir particle on the carbon by reducing the IrOx nano-particle; dispersing the Ir particle on the carbon into a solvent; adding a Pt precursor to the dispersed solution; and reducing into Pt. |
