Abstract

Heating of a ruthenium surface on which carbon monoxide and atomic oxygen are coadsorbed leads exclusively to desorption of carbon monoxide. In contrast, excitation with femtosecond infrared laser pulses enables also the formation of carbon dioxide. The desorption is caused by coupling of the adsorbate to the phonon bath of the ruthenium substrate, whereas the oxidation reaction is initiated by hot substrate electrons, as evidenced by the observed subpicosecond reaction dynamics and density functional calculations. The presence of this laser-induced reaction pathway allows elucidation of the microscopic mechanism and the dynamics of the carbon monoxide oxidation reaction.

The calculated electronic eigenstates i are occupied according to the Fermi function f at finite temperatures f i = f ( ε i T el ) = [1 + exp( ε i − ε F /k B T el ] −1 where ε F is the Fermi energy. The spatial electron density n ( r ) is then optimized to minimize the free energy F [ T el ; n ] = E [ T el ; n ] − T el S [ T el ; n ]. Here S denotes the entropy associated with the occupancy of the Kohn-Sham orbitals. With Fermi broadening S reads [

In principle τ el is dependent on electron temperature and therefore on time (13) but the fact that the response in the two-pulse correlation measurement is slow compared with the pulse duration and the proximity of the O electronic level to the Fermi level imply τ el ( t ) = τ el (0) = τ el .
