Water splitting method and system

A water splitting system comprising at least one electrochemical cell comprising an anode electrode and a cathode electrode, connectable to each other, to be immersed in an electrolyte for use in an oxidation process;

• said cathode electrode being configured and operable to cause reduction of hydrogen ions by electrons;
• wherein said anode electrode comprises a substrate having an electrically conductive surface carrying a chiral system, wherein, upon application of a potential difference between said anode electrode and said cathode electrode, said anode electrode is configured and operable to create electrons and electron holes causing oxidation of water and transfer to electrons between the electrolyte and the substrate;
• wherein said chiral system causes alignment of the spin of transferred electrons released by oxygen during the oxidation of water to thereby create a spin specificity of the electrons transferred through said chiral system and decrease over potential for the oxidation process;
• wherein the water splitting system is configured to cause a potential difference to be applied between the anode electrode and the cathode electrode in which the over-potential for the oxidation process is reduced due to the alignment of the spin of the electrons transferred through said chiral system.
