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
The reconstruction process on a clean Pt ( 110) surface was monitored by infrared reflection absorption spectra of CO on the surface. The adsorbate-induced phase transition from the (1 x2 )-Pt (110) to the ( I x I )-Pt( 110) structure was completely suppressed under negative electrode potentials. Th
