Here we report the theory and experimental study of anomalous diffusion phenomena coupled with facile charge transfer reaction at fractally rough glassy carbon vertical bar room temperature ionic liquid (GC vertical bar 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 vertical bar 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.
