Abstract

Chemical wave patterns that develop in the O2+ H2reaction on a bimetallic Rh(110)/Ni surface have been studied with photoelectron emission microscopy (PEEM) in the 10−6to 10−4mbar range. The bifurcation diagram for Ni coverages up to 3 monolayers (ML) was mapped out forT= 770 K. Stationary concentration patterns of macroscopic stripes as well as target patterns and irregular chemical waves were observed.
