WebThe Briggs-Rauscher (BR) oscillatory chemical systems are composed of iodate, hydrogen peroxide, an organic substrate and a one-electron metal ion catalyst in acid solutions [1]. Thus far, only the Ce 4+/3+ and Mn 3+/2+ redox couples were known to catalyze the BR reaction. Recently we found BR-type
