For the reductive functionalization of SWCNTs in liquid ammonia and THF as co-solvent, alkali metals are used as reducing agents. For a comparison of the different metals in respect to the degree of functionalization it would be important to know the reduction potentials of these different metals. Since the ammonia is capable to react with the standard electrodes my question is how to arrange a usefull setup for the determination of the reduction potentials in this media?
I think Cyclic voltammetry will help you. check out

Thanks for the answer. Of course I will try to measure CV. But my question was related to the setup of the electrodes since I want to know the exact potentials in the liquid ammonia/THF media which is not trivial for CV measurements.
In my Experience BY dealing with Pt, not with the same media off course as you mentioned, i used SCE (as referance) and glassy carbon (working electrode), i think u can try that....
