The rate of anion and hydrogen adsorption on Pt(111) and Rh(111)
Impedance spectra were measured for Pt(111) and Rh(111) electrodes in various electrolytes. They can all be interpreted by assuming one or two parallel adsorption resistances in addition to the double layer capacity. Adsorption of Cl − and HSO 4 − at Pt(111) is very fast and at the limit of detectab...
