Electrochemical Depolymerization of Chitosans Using the IrO₂ Electrode with Interlayers as Anode

Abstract:

A IrO₂ anode on titanium substrate with iridium–titanium oxide interlayer (Ti/ TiO₂-IrO_x/IrO₂) was prepared through repeating brushing-drying-calcinating procedure. The TiO₂-IrO_x interlayer was prepared using a mixture of TiN nanoparticles and H₂IrCl₆ solution as the coating solution. The Ti/TiO₂-IrO_x/IrO₂ had high catalytic activity, good catalytic stability and long service life. It was suitable for the application of electrochemical depolymerization of chitosans. The experimental results showed that chitosan could be effectively degraded using the Ti/ TiO₂-IrO_x/IrO₂ as the anode. The influence of the current density on the degradation of chitosans was complicated. The power supply type obviously influenced on the degradation.
