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