Non-equilibrium surface phase transitions during the catalytic oxidation of CO on Pt(100)

Isothermal low-pressure oscillations of the rate of catalytic CO oxidation on a Pt(100) surface could be established under appropriate conditions and were monitored through the accompanying periodic variation of the work function. Parallel observations by the Video-LEED technique demonstrated that t...

Description
Summary:Isothermal low-pressure oscillations of the rate of catalytic CO oxidation on a Pt(100) surface could be established under appropriate conditions and were monitored through the accompanying periodic variation of the work function. Parallel observations by the Video-LEED technique demonstrated that these oscillations are associated with periodic transformations of the (long-range) surface structure from the reconstructed hex to the 1×1 phase and back, which is caused by varying surface concentrations of the reactin particles.
