Figure 16: (a) Voltammetry curves for an annealed Pd_{3}Fe(111) in 0.1 M HClO_{4} solution with different positive potential windows. (b) Voltammetry curves for an annealed (red line) and a polished Pd_{3}Fe(111) (blue line), and Pd(111) (black line) in 0.1 M HClO_{4} solution. Scan rate: 20 mV s^{−1} [47].
