Abstract

The effects of CH2Cl2 on the room temperature redox behaviors of ferrocene in ionic liquid,BmimPF6,were studied by cyclic voltammetry and AC Impedance.The results suggested that the presence of CH2Cl2,accelerated the dissociation of ionic liquid,leading to lower viscosity and larger ionic conductovity,hence,the diffusions of ferrocence in BmimPF6 were enhanced and the peak currents of redox reactions were increased.The changes in the double-layer structure at the electrode interface resulted in larger capacitance,which reduced the electrode recution resistances,accordirgly,the reaction kinetics of ferrocene were enhanced.
