Abstract

In this chapter the experimental results on adsorption of sulfate ion on Pt(111), Pt(100) and Pt(110) surfaces are described.

Infrared and CV measurements indicate strong adsorption on Pt above 0.15 V (RHE) and a decrease of the oxygen reduction reaction (ORR) by the adsorbed SO42−/HSO4 anions; the sequence is Pt(111)<Pt(100)<Pt(110). The suggested bond geometry is threefold on Pt(111) but twofold on Pt(100) and Pt(110) [1, 2].
