Highly dispersive Pt atoms on the surface of RuNi nanoparticles with remarkably enhanced catalytic performance for ethanol oxidation

A simple method for the preparation of highly dispersive Pt atoms on the surface of RuNi nanoparticles is developed by the deposition of Pt on single-walled carbon nanotube supported RuNi nanoparticles. The anodic peak current density of the nanocomposite is 8.0 times higher than that of Pt/C for ethanol oxidation, and it has a significantly lower onset potential than Pt/C for ethanol oxidation.
