Engineering the Composition and Structure of Bimetallic Au–Cu Alloy Nanoparticles in Carbon Nanofibers: Self-Supported Electrode Materials for Electrocatalytic Water Splitting

The bimetallic Au–Cu alloy nanoparticles have been constructed in electrospun carbon nanofibers (Au–Cu/CNFs), employing as high efficient hydrogen evolution reaction (HER) electrode. The morphology, structure, and composition of bimetallic Au–Cu alloy can be controlled by adjusting the precursor nanofibers through a facile approach. With the increased Cu content, the Au–Cu alloy have a transition from the homogeneous AuCu3 alloy phase to the...
