Weexplore the effect of boundary curvature on the instability ofreactive pulses in the catalytic oxidation of CO on microdesignedPt catalysts. Using ring-shaped domains of various radii, we findthat the pulses disappear (decollate from the inert boundary) ata turning point bifurcation, and we trace this boundary inboth physical and geometrical parameter space. These computations corroborate experimentalobservations of pulse decollation.
