Facile one-step room-temperature synthesis of Pt3Ni nanoparticle networks with improved electro-catalytic properties.

Pt(3)Ni alloy nanoparticle networks (Pt(3)Ni NN) were prepared through a simple one-step room-temperature synthetic method. The as-prepared Pt(3)Ni NN exhibited markedly improved activity for both oxygen reduction reaction and electrocatalytic oxidation of small organic molecules over the Pt nanoparticle networks (Pt NN) and commercially available Pt/C.
