I am investigating the redox behavior of Diene compounds by cyclic voltammetry in anaerobic environment. My electrodes include carbon glassy electrode as working electrode, platinum as counter and silver/silver chloride as reference. My solvent is THF and supporting electrolyte Tetra(n-butyl)ammonium Hexafluorophosphate. The problem I have is that I cannot see the redox peaks for these electron transfers. Can anyone give me some advice on how to optimize the situation?
This is a very common phenomenon in electrochemistry if you don't see any peak. The rate of electron transfer is too slow, or at higher/lower than potentials of your solvent.
Try the experiment with different electrolyte concentrations at a lower scanning rate. Lower scan rates can sometimes make it easier to observe redox peaks.
