Actually, I want to use ferrocene as a refence electrode to measure the EIS of perovskite catalyst. and should I follow the same steps as that electrochemical cell contains Ag/AgCl as a reference electrode (like using the same volt and frequencies).

The absolute value of the electrode potential of a ferrocene electrode cannot be measured. Therefore, it must be measured relative to the hydrogen electrode or other standard electrodes. Otherwise, you will not be able to compare the value of the electrode potential with others in the scale of known potentials.
Thank you for your time,
But, do you think if l find a paper mentioned that the oxidation potential of ferrocene vs NHE in certain solvent such as Acetonitrile, l can use it?
I think you'll find that Ag/AgCl isn't very compatible with non-aqueous electrolytes and ferrocene cannot dissolve in aqueous solutions.

You can measure the potential in acetonitrile according to the method that you will find in the article and compare the potentials in this medium. The well-known scale of electrode potentials refers to water systems.
