Why do semicircle and Linear region appear in Nyquist plots in Electrochemical Impedence Spectroscopy?

11 November 2014 1 7K Report

What is the meaning of electron/charge transfer limited process which we assign to semicircle and mass transfer limited process which we assign to linear part?

What actually happens there consider polyaniline as example?

Rasu Muruganantham

The EIS semicircle and Linear region is due to a combination of kinetic and diffusion processes. This is my simply & short ans. If you refer the following article may be very useful for your qusn.

Is it necessary that a composite of metal oxide and rGO should always exhibit better energy storage properties compared to only metal oxide and rGO?

Kindly shed some light on it. In my case, the rGO alone is providing better supercapacitor properties than composite.
