Highly stable and active PtNiFe dandelion-like alloys for methanol electrooxidation

Novel PtNiFe dandelion-like alloys are fabricated by a facile etching strategy. The ternary alloys and single-walled carbon nanotube (SWNT) immobilized PtNiFe alloys exhibit high activity and poison tolerance with remarkable stability for methanol oxidation reaction (MOR). The excellent electro-catalytic performance is ascribed to the unique dandelion-like nanostructure.
