Abstract

Stepped surfaces with (111) terraces may be divided in two classes: those with (100) steps and those with (111) steps. The hard-sphere model for these surfaces taken as a guide for the analysis of their hydrogen electrosorption voltammograms was proved to work correctly for the counting of step and terrace sites. Moreover it yields information about the atomic configuration of the step sites, i.e. the position of the ledge atomic row relative to the underlying terrace rows.
