Abstract
The composition- and structure-controlled synthesis of bimetallic nanostructures is highly important for the design of highly active electrocatalysts. Herein, we report a one-step strategy for the efficient synthesis of bimetallic PtCo nanodendrites at high yield in an aqueous solution at room temperature. The newly designed bimetallic PtCo nanodendrites with a porous dendritic surface offer sufficient molecular accessible active sites and are highly active and durable catalysts for oxygen reduction reaction in comparison with bimetallic PtCo nanoflowers and commercially available Pt/C catalyst.
Bimetallic PtCo nanodendrites are synthesized by a high yield and one-step method in an aqueous solution at room temperature. The nanodendrites are a highly active and durable catalyst for oxygen reduction reaction. [Display omitted]
