Abstract
Photoelectron emission and scanning photoelectron microscopies have been used to study the mass transport of potassium on the surface of a Rh(110) catalyst with Pt microstructures, induced by propagating chemical waves during the H2 + O2 reaction or by coadsorption of NO. Imaging the dynamic changes in the adsorbed layer, an energetically driven redistribution of K and formation of condensed coadsorbed patterns on the Rh(110) surface has been evidenced. The local composition of the different patterns on this spatially heterogeneous interface has been determined by microspot photoelectron spectroscopy, and the mechanism of the observed self-organization processes has been verified.
