Abstract
Electrochemical dispersion of Pt70Cu30 alloy implemented by applying repeated 100 V/--10 V voltage pulses is proposed as a one-step method to produce a composite electrocatalyst of the oxygen reduction reaction (ORR). A comparative study of the catalytic activity towards ORR of the obtained composites based on few-layer graphene structures decorated with PtCu nanoalloy and pure Pt nanoparticles was carried out. The prospects of using the electrochemical sputtering of PtCu alloy for the one-step production of effective electrocatalysts were substantiated.
