Fig. 5

a–d SEM image of the porous platinum obtained at −1 V from aqueous 0.5% PtCl4 at 0% (a), 0.01% (b), 0.03% (c), 0.05% (d) Pb(CH3COO)2; e–h EDX of the porous layer at 0% (e), 0.01% (f), 0.03% (g), 0.05% (h) Pb(CH3COO)2. Lead is removed from the porous platinum layer by dissolution with HClO4 or by sublimation at 600 °C.
