Area of Science:

  • Surface science
  • Heterogeneous catalysis
  • Materials chemistry

Background:

  • Understanding water formation on metal surfaces is crucial for catalysis.
  • The Rh(110) surface is a model system for studying surface reactions.
  • Previous studies proposed models for water layers on metal surfaces.

Purpose of the Study:

  • To characterize the structural evolution during water formation on Rh(110).
  • To investigate the reaction mechanism of water formation on a pre-oxygenated Rh(110) surface.
  • To propose models for intermediate structures formed during the reaction.

Main Methods:

  • Scanning tunneling microscopy (STM) for atomic-scale surface imaging.
  • Density functional theory (DFT) calculations for theoretical analysis.

  • Exposure of a (2 x 1)p2mg-O structure on Rh(110) to molecular hydrogen.

    • Main Results:

    • The reaction initiates as a wave front, reducing oxygen coverage.
    • Intermediate structures, including c(2 x 4) and c(2 x 2) phases, form sequentially.
    • The c(2 x 2) phase, possibly a mixed H+O structure or a half-dissociated water layer, facilitates complete hydrogenation and leaves a clean Rh surface.

    Conclusions:

    • The water formation reaction on Rh(110) proceeds through well-defined structural intermediates.
    • Two plausible models for the c(2 x 2) structure involving hydrogen bonding were proposed.
    • The reaction pathway ultimately leads to the removal of oxygen and a clean rhodium surface.
