Abstract

The effect of local periodic forcing on uniformly oscillating CO oxidation on a Pt(110) surface is investigated utilizing our recently developed addressable catalyst approach. The heating, provided by a focused laser beam, serves as the locally applied external force. The observations are ascribed to the interaction between local actuation and global coupling through the gas phase leading to the suppression of the locally developed patterns.
