Abstract

The PtAu alloy nanowire networks (NWNs) were synthesized directly in an aqueous solution using Triton X-114 as the structure-inducing agent. The NMNs formed based on the oriented-attachment growth mechanism, and they exhibited dramatically enhanced electrocatalytic activity for formic acid electrooxidation compared with commercial Pt black. Besides the ensemble effect, the advantages of the unique structure, including superior electrical conductivity and faster electron-transfer for the electrochemical process, were regarded as the contributors to the superior catalytic activity of the as-prepared PtAu NWNs.
