| Research Abstract |
We have determined the real surface structures of the high index planes of Pt and the single crystal electrodes of Pd in electrochemical environments. Pt surfaces with 2 atomic rows of terrace (Pt(110)=2(111)-(111) and Pt(311)=2(100)-(111)) are reconstructed to (1×2) structure, whereas those with 3 atomic rows of terrace have (1×1) structure (Pt(310)=3(100)-(110), Pt(511)=3(100)-(111), Pt(331)=3(111)-(111)). The in-plane structures and the interlayer spacings do not depend on the applied potentials on the high index planes. These results differ from those on the low index planes of which interlayer spacings are expanded in the adsorbed hydrogen region.
