Adv Mater. 2016 Mar 9;28(10):2077-84. doi: 10.1002/adma.201504785. Epub 2016 Jan 12.

Abstract

PtFeCo alloy nanostructures in a TriStar shape with tunable Fe and Co content are developed for the electrocatalytic hydrogen evolution reaction (HER). With electronic and surface structures well-tailored, the PtFeCo nanostructures exhibit dramatically enhanced performance in HER against commercial Pt/C and other Pt-based nanoparticles.

Keywords: alloy lattices; d-band centers; electrocatalysis; hydrogen evolution reactions; nanostructures.
