Abstract

In this chapter the experimental results on adsorption of sulfate ion on Pt(100) surface is described.

Starting at 0.2 V (Pd/H2), SO42− adsorbs on Pt(100) and reaches a maximum at 0.5 V. SNIFTIRS (Subtractively normalized interfacial Fourier transform infrared spectroscopy) indicates only weak adsorption of HSO4 below 0.4 V (Pd/H2), a rearrangement (possibly deprotonation) of HSO4, or a weak adsorption of SO42−. Two strong IR bands at 1100 cm−1 and 1200 cm−1 are assigned to the two symmetric O-S-O groups (involving the coordinated and uncoordinated O-atoms) [1, 2].
