# Is the thermodynamic stability against reduction/oxidation of an electrolyte dependent on the electrode material?

Consider an electrochemical cell with an inert Pt working electrode (WE) and some electrolyte that irreversibly decomposes upon oxidation. A minimum potential $$E_{min}$$ (vs. some reference) needs to be applied to the WE to allow oxidation to occur (but most likely a higher value is required to actually measure a current). I would call this potential the thermodynamic stability potential limit (SPL).

Does this minimum potential change when exchanging the WE material with another inert material, e.g. glassy carbon? I think it should not, as all that matters is the electrochemical potential/fermi level in the inert electrode.

Could some type of specific adsorption of electrolyte components change (lower) the thermodynamic SPL? To me this sounds like catalysis, which just influences kinetics, not thermodynamics.

What about adding some other substance? Could its reaction products cause degradation of the electrolyte components in some way?
