Effects of external global noise on the catalytic CO oxidation on Pt(110)
P. S. Bodega, S. Alonso, H. H. Rotermund
Oxidation reaction of CO on a single platinum crystal is a reaction-diffusion system that may exhibit bistable, excitable, and oscillatory behavior. We studied the effect of a stoc…
Enhancement of surface activity in CO oxidation on Pt(110) through spatiotemporal laser actuation
L. Qiao, X. Li, I. G. Kevrekidis +2
We explore the effect of spatiotemporally varying substrate temperature profiles on the dynamics and resulting reaction rate enhancement for the catalytic oxidation of CO on Pt(110…
Guiding chemical pulses through geometry: Y-junctions
L. Qiao, I. G. Kevrekidis, C. Punckt +1
We study computationally and experimentally the propagation of chemical pulses in complex geometries.The reaction of interest, CO oxidation, takes place on single crystal Pt(110) s…
Geometry-induced pulse instability in microdesigned catalysts: the effect of boundary curvature
L. Qiao, I. G. Kevrekidis, C. Punckt +1
We explore the effect of boundary curvature on the instability of reactive pulses in the catalytic oxidation of CO on microdesigned Pt catalysts. Using ring-shaped domains of vario…
Pattern Formation on the Edge of Chaos: CO Oxidation on Pt(110) under Global Delayed Feedback
Matthias Bertram, Michael Pollmann, Harm H. Rotermund +2
Experiments with catalytic CO oxidation on Pt(110) show that chemical turbulence in this system can be suppressed by application of appropriate global delayed feedbacks. Different…
