Abstract
The invention provides methods for producing hydrogen and oxygen, comprising the steps of: (i) oxidising a mediator at a working electrode to yield an oxidised mediator, and reducing protons at a counter electrode to yield hydrogen; and (ii) reducing an oxidised mediator at a working electrode to yield a mediator, and oxidising water at a counter electrode to yield oxygen, wherein the oxygen generation step is performed non-simultaneously to the hydrogen generation step, and the oxidised mediator of step (i) is used as the oxidised mediator of step (ii), or the mediator of step (ii) is used as the mediator of step (i), and the mediator has a reversible redox wave lying between the onset of the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER).
