Surface-enhanced Raman spectra (SERS) from a roughened platinum electrode in formic acid-containing dimethylformamide solutions have been examined combined with cyclic voltammetry techniques. The occurrence of surface poisoning by CO adsorption was confirmed by observation of both Pt-CO and internal
At least two different solution species were adsorbed on a Pt(l I 1) electrode in acid solutions; one is neutral H 20, and the other the hydronium ion H3 O+. The former neutral molecule chemisorbed through an oxygen lone pair to a hydrogen covered platinum surface. At potentials more positive than 0
