Large amplitude excitations traveling along the interface in bistable catalytic methanol oxidation on Rh(110)

Author affiliations

Abstract

Traveling interface modulations have been observed in catalytic methanol oxidation on an unpromoted Rh(110) and a partially vanadium oxide covered (θV = 0.1 MLE) Rh(110) surface. The front instabilities have been followed with photoemission electron microscopy (PEEM) in the 10−4 mbar range at T ≈ 800 K where the reaction is bistable. Near the equistability point large amplitude excursions (up to 300 μm) from the average interface position occur which travel in a pulse-like manner along the interface.
