Investigation of the electroreduction of silver sulfite complexes by means of electrochemical FFT impedance spectroscopy
چکیده انگلیسی
The electroreduction kinetics of silver sulfite complexes was investigated by electrochemical fast Fourier transform (FFT) impedance spectroscopy (0.061-1500 Hz). The time dependences of the real and imaginary components of impedance were determined in a solution containing 0.05 M Ag (I) and 1 M Na2SO3. The mean duration of silver ad-atom diffusion on the surface to the nearest crystallization centre was calculated: during the first 210 s of contact with the electrolyte, these values increase from 0.66 up to 1.77 s; thereafter, this variation stabilizes and the mean duration of silver ad-atom diffusion reaches an almost constant value (1.56 s).
