Anomalous fluctuations in current transient at glassy carbon|room temperature ionic liquid interface

Here we report the theory and experimental study of anomalous diffusion phenomena coupled with facile charge transfer reaction at fractally rough glassy carbon|room temperature ionic liquid (GC|RTIL) interface. A finite self-affine scaling property has been exhibited by a realistic fractal electrode surface. A comparison of classical Cottrell equation with the present theoretical model to account for the experimentally recorded current transients across GC|RTIL interface is also presented. This model gives information about various morphological features of electrode surface. An excellent correspondence of calculated and reported diffusion coefficient is also obtained.
