Abstract

The first observations of Li-modified isothermal kinetic oscillations during CO oxidation on a Pt field emitter tip are reported. The oscillations are realized on the surface of a [111]-oriented Pt tip in the presence of a Li submonolayer coverage of about 2.5 × 10¹⁴cm⁻² and are compared to the corresponding Li-free oscillations occurring on the same tip. In both cases the oscillatory process is visualized using the field electron emission (FEM) mode of the lithium field desorption microscope (Li-FDM). The origin of the FEM imaging contrast of coadsorbed Li-CO and Li-O layers on Pt is clarified. The influence of the coadsorbed Li submonolayer on the oscillating behavior of CO oxidation on Pt is discussed.
