Abstract

By employing mirror electron microscopy (MEM) to image the Pt(110) surface during the catalytic oxidation of CO we observe that a fine cellular structure (typical dimension 1–5 μm) develops under conditions at which rate oscillations occur. Based on an analysis using the complex Ginzburg-Landau equation, it is demonstrated that such a structure forms generally in an oscillatory medium in the presence of global coupling.
