| Description |
Sea water electrolysis is one of the promising ways to produce hydrogen since it is available in plentiful
supply on the earth. However, in sea water electrolysis toxic chlorine evolution is the preferred reaction
over oxygen evolution at the anode. In this work, research has been focused on the development of electrode
materials with a high selectivity for oxygen evolution over chlorine evolution. Selective oxidation in
sea water electrolysis has been demonstrated by using a cation-selective polymer. We have used a permselective
membrane (Nafion), which electrostatically repels chloride ions (Cl) to the electrode surface
and thereby enhances oxygen evolution at the anode. The efficiency and behaviour of the electrode have
been characterized by means of anode current efficiency and polarization studies. The surface morphology
of the electrode has been characterized by using a scanning electron microscope (SEM). The results
suggest that nearly 100% oxygen evolution efficiency could be achieved when using an IrO2/Ti electrode
surface-modified by a perm-selective polymer.
