    “…In this work, we have used a galvanostatic method to co‐deposit PtNi films onto polycrystalline gold. The surface concentrations of Ni (Γ(Ni)) and Pt (Γ(Pt)) were calculated from electrochemical measurements; the Γ(Pt)/Γ(Ni) ratio and electrocatalytic activity of these materials towards hydrogen evolution reaction (HER) in 1 M KOH show a strong dependence on the current density pulse applied during the electrodeposition. …”

    “…The experimental results revealed that the catalytic efficiency as well as the charge transfer resistance (at the redox potential of the Fe(ii)/Fe(iii) couple) increased in the order of Pt < Pt–Pd < Pt–Pd(sds). A Pt–Pd(sds) electrode exhibited an open circuit potential (OCP) of 0.65 V in acidic conditions; however, when 50.0 mM NaAsO(2) was present, the OCP value shifted to 0.42 V. …”
