چکیده انگلیسی
A phenomenon of current oscillators was characterized crosswise active–passive potential region during the electrodissolution of copper electrode in trifluoroacetic acid (TFA). The current density-potential curves show two transition points. A potential region of current oscillations was found as a part of limiting current region. The Cu|TFA electrochemical oscillator was found to displaying rich dynamical response on varying the temperature and the applied potential. The Cu|TFA system display current oscillation behaviour from the mono-periodic to the mixed-mode (relaxation type). Changes of the electrode surface structure and morphology were investigated by X-ray diffraction spectroscopy, atomic forced microscopy and optical microscopy.
