a Cyclic voltammogram of PdMLPt(111) electrode (red) and Pt(111) (black) in 0.1 M HClO4. b Voltammograms for the oxidation of formic acid on PdMLPt(111) electrode (red) and Pt(111) (black) in 0.1 M HClO4 + 50 mM HCOOH. The evolution of 12 cycles on a rotating PdMLPt(111) (red) and Pt(111) (black) electrode at 1600 rpm with continuous cycling to two lower vertex potentials: one to the potential of the oxidation peak where no oxidative stripping of adsorbed CO takes place (see panel c), and one to a higher potential at which adsorbed CO is oxidatively stripped off. Scan rate: 50 mV s−1. c CO stripping voltammogram for PdMLPt(111) electrode (red curve) and Pt(111) (black curve) in 0.1 M HClO4. Scan rate: 10 mV s−1.
