One-pot synthesis of PtIr tripods with a dendritic surface as an efficient catalyst for the oxygen reduction reaction

Author affiliations

Abstract

Pt-based nanocrystals with a dendritic structure are highly attractive materials for various electrocatalytic applications owing to their high surface area. Herein, a facile one-pot method is presented for the controlled synthesis of PtIr tripods with a dendritic surface (PtIr DTPs), which is achieved by the reduction of Pt and Ir metallic precursors in oleylamine and NH4F with H2. The unique PtIr DTPs exhibited superior catalytic activity and durability towards the oxygen reduction reaction (ORR). The newly developed one-pot approach is feasible for the synthesis of dendritic tripod Pt-based NCs with a designed composition for various catalytic applications.
