Abstract: The electrochemical characterization of chemical carbonyl route generated Pt:Ni nano-alloys, in acid and alkaline media, is reported. Earlier XRD and Debye Function Analysis (DFA) studies (Yang et al., 2004 [ 1 ]) provided the structure of these nanoalloys. Herein, the HER/HOR electrocatalytic activity as well as ORR kinetics, in alkaline medium, was determined and correlated with the interatomic Pt Pt distance. The HER/HOR and ORR exchange current densities describes a Volcano-like plot. For both systems, the maximum activity for both processes peaked with Pt 3 Ni. • Pt:Ni nanoalloy materials were synthesized by the carbonyl chemical route. • The HER/HOR and ORR processes were investigated in alkaline electrolyte. • The nanoalloy with the optimal electrochemical activity was Pt 3 Ni. • The oxophilic effect is favored for the HER/HOR in alkaline electrolyte. • The catalytic center's strain effect is found in the nanoalloy itself.
