In-situ FTIR spectroelectrochemical investigation of cobalt(II)-cyanoferrate polymeric film coated on a glassy carbon electrode.
Cobalt(II)-cyanoferrate polymeric film has been electrochemically deposited on a glassy carbon electrode and investigated by cyclic voltammetry and in-situ reflection FTIR spectroscopy. A reorientation of the terminal CN groups upon redox reactions was proposed. The stretching vibration mode of the terminal CN groups associated with Fe(III) was observed at 2122 cm(-1), however, the stretching vibration mode for terminal groups associated with Fe(II) did not appear. This process could result in a switch between lattice-closed and lattice-opened surface structure.
