摘要: Abstract The oscillatory behaviour of CO oxidation was studied at 250 °C and atmospheric pressure using an electrochemical catalyst composed a thin (60 nm) sputtered-Pt film interfaced with yttria-stabilized zirconia membrane. Oscillations rate showed perfect correlation those the potential values. Electrochemical promotion catalysis used to initiate stop behaviour. Small current application induced permanent effect on behaviours. An extremely small negative (− 17 μA) led 4-fold increase catalytic activity created oscillations that were stable even after interruption. This in is observed for first time EPOC. has been interpreted by higher tendency nanometric-Pt particles form PtO x sputtered films.
