AB  - Hydrogen and bisulphate adsorption at platinum single crystal surfaces from the [ITO] zone is
strongly dependent on the crystallographic orientation of the electrode surface, which is similar to that
found earlier for the [llO] zone. For the purposes of comparison, some experiments were performed with
non-adsorbing perchlorate acid solutions. The multiple states of hydrogen adsorption can be correlated
with symmetry of surface sites and the nature of the adsorbed oxi-anions. All stepped surfaces
investigated from this zone have one sharp peak at -0.175 V which is due to a coupled desorption of
bisulphate and hydrogen adsorption from the sites with the (110) symmetry. The surfaces of the
n(llO)-(lll) type behave as the surfaces denoted (n -1X110)-3(111) since the three atom long terrace is
“seen” by bisulphate and hydrogen.
Bisulphate anions are more strongly adsorbed at the steps than at the (111) oriented terraces, The
latter process occurs at more positive potentials than the adsorption at steps and it is affected by anions
at the step sites. The structure in the electrolyte solutions has been discussed.
