Voltammetric characterization of Pt single crystal electrodes with basal orientations in trifluoromethanesulphonic acid

The behaviour of platinum single crystal electrodes in 0.1 M trifluoromethanesulphonic acid (TFMSA) is reported. The electrode–solution interface depicts the characteristics observed in absence of specific adsorption. At Pt(1 1 0) a small increase of the potential of zero total charge is envisaged. Water splitting region is slightly different than that at perchloric acid solutions thus precluding differences in water adsorption that are reported to be important in electrocatalysis.
