Three-dimensional (3D) Pt-based alloy nanostructures composed of one-dimensional (1D) nanowires/nanorods have recently attracted significant interest as electrocatalysts. In this work, we report an effective solvothermal method for the direct preparation of 3D Pt-Co nanowire assemblies (NWAs) with tunable composition. The composition- and structure-dependent electrocatalytic performance is thoroughly investigated. Because of the bimetallic synergetic effect and unique structural advantage, the as-prepared 3D Pt3Co NWA outperforms commercial Pt/carbon and Pt black catalysts and even 3D Pt NWA. The electrochemical results demonstrate that the 3D Pt3Co NWA is indeed a promising electrocatalyst with enhanced catalytic activity and improved durability for practical electrocatalytic applications. Three-dimensional (3D) Pt-Co alloy nanostructures with tunable composition are synthesized by an effective solvothermal method. The interconnected 3D Pt3Co nanowire assembly exhibits significantly enhanced electrocatalytic activity and durability compared with commercial Pt based catalysts and a 3D Pt nanowire assembly. This is mainly attributed to the synergetic effects from composition and structural advantages. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
