On the basis of the above observations, Angerstein-Kozlowska and colleagues (1973) reasoned thus even at peak Oa3, less than 1 electron per Pt atom has passed, therefore, it is highly unlikely that the oxidation of the surface proceeds via a single two-electron process, i.e. ...

A pronounced structural sensitivity of the oxidation of Pt surfaces is also seen in Fig. 1. The reaction takes place at the most positive potential on Pt(lll). This is probably due to effective blocking of the surface by oxy-anions with the trigonal symmetry, compatible with the (111) orientation. A detailed analysis of this reaction on Au(lll) has been recently performed by Angerstein-Kozlowska et al. (14). No such blocking is possible for the Pt(100) and Pt(110) surfaces with four-fold and two-fold symmetries. Consequently, the oxidation commences at more negative potentials, probably predominantly determined by the surface energy as found with Au (16).
