Rational One-Step Synthesis of Porous PtPdRu Nanodendrites for Ethanol Oxidation Reaction with a Superior Tolerance for CO-poisoning

Abstract

Precise fabrication of porous ternary Pt-based nanodendrites is very important for electrochemical energy conversion, owing to their high surface area and high molecular accessibility. Herein, PtPdRu porous nanodendrites (PNDs) were prepared via a facile one-step ultrasonic irradiation approach at room temperature. The ultrasonic irradiation drove the formation of PtPdRu PNDs with spatially interconnected porous structure, while magnetic stirring produced PtPdRu nanoflowers (NFs) with less porous structure. The formation mechanism was ascribed to the acoustic cavitation effect and fast-reduction kinetics under sonication. As-made PtPdRu PNDs displayed a superior catalytic performance towards ethanol oxidation reaction with a high tolerance for CO-poisoning compared with PtPdRu NFs, PtPd NFs, and commercial Pt/C catalyst.
