Controllable Synthesis and Characterization of AuPd Nanowire Networks with High Electrocatalytic Performance.

A simple and efficient method is proposed for the synthesis of bimetallic AuPd nanowire networks (NWs) with tunable compositions by using KBr as a structure-directing agent and NaBH₄ as a reducing agent. TEM, XRD and XPS results show that the AuPd NWs have a unique one-dimensional network structure. Electrochemical tests indicate that the AuPd NWs catalysts have excellent electrocatalytic activity and durability for methanol oxidation due to the special one-dimensional nanostructure and many structural defects at the junction.
