Abstract

We evaluated the oxygen reduction reaction (ORR) properties of ultra-thin Pt shell layers prepared on nitrogen ion beam (N₂⁺ beam), and neutralized nitrogen ion beam (N₂₀ beam) irradiated Pt₂₅Ni₇₅(111) substrates. Although the non-N₂ irradiated 0.9-nm-thick Pt layers on Pt₂₅Ni₇₅(111) (Pt_0.9nm/Pt₂₅Ni₇₅(111)) showed a kinetic-controlled current density (j_k) of 7.7 mA/cm², the j_k values for the Pt_0.9nm/N₂⁺-Pt₂₅Ni₇₅(111) and Pt_0.9nm/N₂₀-Pt₂₅Ni₇₅(111) pristine surfaces are 6.6 and 6.3 mA/cm², respectively. In contrast, the N₂₀ beam irradiated sample displayed better durability by retaining ca. 90% of the initial j_k value, while the j_k values for the N₂⁺ irradiated and non-irradiated samples decreased to ca. 70% and 60%, respectively, of the initial value. The result suggests that N₂₀ beam irradiation on the Pt₂₅Ni₇₅(111) substrate is effective for the electrochemical stabilization of the ultra-thin Pt-shell layers.
