Abstract

The propagation of periodic reaction-diffusion waves (wave trains) on a composite catalytic surface, whose subdomains are characterized by different reaction kinetics, is observed experimentally during CO oxidation and analyzed computationally with a realistic reaction-diffusion model. Complete transmission as well as partial blocking of plane waves, creation of spirals as well as chemical turbulence due to presence of a domain boundary with curved waves are found for different parameters.
