The problem of non-stationarity in experimentally recorded time-series is common many (electro)chemical systems. Underlying this the slow drift some uncontrollable parameter, and it occurs spite fact that all controllable parameters are kept constant. Particularly for electrochemical systems, us have recently suggested [J. Phys. Chem. C, 144, (2010), 22262-22268] an empirical method to stabilize experimental time-series. was exemplified electro-oxidation methanol different patterns were satisfactorily stabilized. In paper we further elaborate mechanistic aspects test formaldehyde, a system has resemblance with methanol, but produces richer dynamics. terms reaction mechanism, able describe coupling separate surface processes two sub-systems: fast one (or core-oscillator) one, responsible drift.
