Ultralow platinum-loading bimetallic nanoflowers: Fabrication and high-performance electrocatalytic activity towards the oxidation of formic acid

Ultralow Pt-loading bimetallic nanoflowers have been fabricated by Cu under-potential deposition and galvanic exchange process. Results show that these Pt monolayer coated Au nanoflowers have superior performance towards oxidation of formic acid through a dehydrogenation pathway. (C) 2012 Elsevier B.V. All rights reserved.
