Abstract

The Belousov–Zhabotinsky (BZ) reaction is the best known example of far from equilibrium self-organizingchemical reaction. Among the many dynamical behaviors that this reaction can exhibit, spatiotemporalchaos attracted particular interest, both for the ferroin and cerium catalyzed systems. In recentyears transient chaos was found in the cerium catalyzed BZ reaction, when conducted in batch andunstirred reactors. It was established that the chaotic oscillations, originated by the coupling amongchemical kinetics and transport phenomena, appeared and disappeared following a Ruelle–Takens–Newhouse scenario. In this Letter, we show results about the ferroin catalyzed system conducted in batchand unstirred reactors. An aperiodic transient regime was detected and we show that this is a genuinemanifestation of spatio-temporal chaos.
