Surface science studies reveal atomic-scale details of heterogeneous catalysis. Techniques like scanning tunneling microscopy visualize reactions such as CO oxidation and hydrogen oxidation on single crystal surfaces.

Area of Science:

  • Surface science and heterogeneous catalysis.
  • Physical chemistry and materials science.

Background:

  • Investigating well-defined single crystal surfaces provides insights into elementary processes in heterogeneous catalysis.
  • The surface science approach is applicable to real-world catalysis, exemplified by ammonia synthesis.

Purpose of the Study:

  • To demonstrate the success of the surface science approach in understanding catalytic reactions.
  • To observe catalytic reaction progress at an atomic scale using advanced surface techniques.
  • To explore the limits of thermal equilibrium in surface rate processes.

Main Methods:

  • Utilizing scanning tunneling microscopy (STM) and other surface physical techniques.
  • Employing ultrafast (femtosecond) laser techniques to probe surface dynamics.

  • Studying reactions on well-defined single crystal surfaces (e.g., Pt(111), Ru).

    • Main Results:

    • CO oxidation on Pt(111) occurs along boundaries between adsorbed O and CO patches.
    • Ruthenium (Ru) transforms to RuO2 under atmospheric pressure, forming coordinatively unsaturated sites (cus) active for catalysis.
    • Hydrogen oxidation on Pt(111) exhibits autocatalysis, leading to surface concentration patterns characteristic of nonlinear dynamics.

    Conclusions:

    • Surface science techniques offer atomic-scale resolution for understanding complex catalytic mechanisms.
    • Reaction pathways and active sites can be identified on single crystal surfaces.
    • Ultrafast laser methods reveal non-equilibrium dynamics in surface reactions.
