Acetaldehyde oxidation was studied on well-ordered Pt(111), stepped Pt(554), and disordered Pt(111). Random superficial defects of the {110}-type were electro-generated on well-ordered Pt(111) surface by successive potential cycling at 0.05 V s−1 b

In the present study, random superficial defects of the {110}-type were electrogenerated on an initially well-ordered Pt(111) single crystal electrode, by cycling the potential in the range from 0.05 to 1.30 V by 32 times in perchloric acid solution

In the present work, the Pt(111) surface was disordered by controlling the density of {110}- and {100}-type defects. The cyclic voltammogram (CV) of a disordered surface in acid media consists of three contributions within the hydrogen adsorption/des
