In this Accepted 3 March 2012 study, the electrochemical reduction of several PCEs has been investigated in DMF + 0.1 M (C3 H7 )4 NBF4 Available online 10 March 2012 at Ag, Au, Pd, Pt, Cu, Fe, Ni, Pb, Zn and glassy carbon (GC), the last used as a reference system with neg- ligible catalytic properties. The reduction potentials of all investigated PCEs are remarkably influenced Keywords:
